Release Notes GoldSim 14.0

Enhancements and Corrections in 14.0 R4 (#471)

GoldSim 14.0 Revision 4 was released on October 4, 2024.

• FIX Information Delay element produces incorrect results when delay is equal to or exceeds 200 timesteps. [5986]
• FIX Log-Triangular distribution with identical values for inputs gives incorrect result. [5995]
• FIX GoldSim terminates when denying file overwrite during result export. The problem occurs when user chooses not to export when asked. [5993]
• FIX Automatically exporting time history realization results to a text file at end of simulation, which causes GoldSim to end unexpectedly. [5988]
• FIX Changing Tab Order of Result Window in Dashboard Temporarily Breaks Display, causing displays to suddenly show as empty until user navigates away and comes back to refresh the view. [5982]
• FIX Constant Vmol incorrectly shows 'm^3/mol' instead of 'm^3'. It represents the volume of a mol of gas at STP in GoldSim. The tooltip should display 'm^3' only, as changing it to 'm^3/mol' would disrupt existing models. [5984]
• FIX Cell flow balance warnings are incorrect if there are multiple flows and at least one is negative. For Cell elements, we compare the sum of inflows to outflows for the reference fluid. If positive and the Cell volume is static, a warning is written to the Run Log. Negative outflows are treated as inflows. An error occurs with multiple flows if at least one is negative, leading to incorrect warnings. [5985]

• Corrected an issue in the Reliability Component tool-tip where the Mean Time to Repair is shown for the Mean Time to Failure and N/A is always shown for the Mean Time to Repair. [5397]
• Corrected an issue in the Run Controller where the current simulation time may be cut off. [5399]
• Increased the maximum dynamically-controlled duration for a SubModel to 100 billion years. [5402]
• Corrected an issue in the Time Series function (i.e. lookup) capability where an incorrect result may be returned if the Time Series is in a static model. [5414]
• Increased the maximum possible number of displayed SubModel-based histories in a Time History result from 1000 to 10,000. [5415]
• Modified the tool-tip contents for a SubModel to display the function sequence index when "Show causality sequence element tool tips" is enabled in the Causality Sequence dialog. [5428]
• Corrected an issue where a negative discrete change applied to a Pipe or Aquifer element generates an access violation error. Now a proper fatal error message is displayed. [5429]
• Modified time stepping logic to respect (rather than ignore) requests to limit the next time step length even if 'invisibly small' (less than 12 significant figures different from the current etime). [5441]

Enhancements and Corrections in 11.1.5

GoldSim 11.1.5 is a maintenance release (update 5) of GoldSim 11.1. GoldSim 11.1.5 was released on March 3, 2016. 

• Improved the Monte Carlo Latin Hypercube Sampling algorithm (LHS) to minimize correlation within non-scalar Stochastic elements. Note that non-scalar Stochastic elements generate different results for any but the first array item (when comparing with results generated in GoldSim 11.1.4; assuming 'Repeat Sampling Sequence' is enabled). For more information search for 'Improved LHS implementation for non-scalar Stochastics' on the GoldSim Help Desk site. [5362]
• Corrected an issue that prevented GoldSim Player from saving the model file using the 'Save' or 'Save as' menu. [5374]
• Fixed an issue that might cause GoldSim to crash when deleting an element from the Array Label Set editor via the 'Show References' window. [5369]

• Fixed an issue that might cause GoldSim to crash when expanding an invalid RL Component node in the logic-tree of a Reliability Component. [5371]
• Fixed an issue that might cause GoldSim to terminate on Windows 7 when turning off a Reliability Component's 'Model as system' state. [5372]
• Corrected an issue with storing of huge/tiny high resolution history results. GoldSim would trigger an overflow/underflow floating-point exception when converting a result value requiring double precision to single precision. The corrected implementation stores result values exceeding the largest single-precision float value as 3.402823466e+38F and result values smaller than 1.175494351e-38F as zero (0.0). This is analogous to how regular (non high resolution) time history result values are stored. [5373]
• Corrected an issue causing GoldSim to not recognize a valid license on some non-English operating systems. [5375]

Enhancements and Corrections in 11.1.4

GoldSim 11.1.4 is a maintenance release (update 4) of GoldSim 11.1. GoldSim 11.1.4 was released on February 12, 2016. Enhancements and corrections in this version are listed below:

• This release of GoldSim introduces a powerful and flexible licensing system. Detailed information is provided in the GoldSim Licensing End-User Manual, which can be found in the GoldSim installation folder (GoldSim_Licensing.pdf).
  Note: The new licensing system is simultaneously introduced for GoldSim products 10.5, 11.0 and 11.1. Updates supporting the new licensing system are available on our website. [5346, 5349, 5355]
• Fixed an issue when exporting multi-variate table data files, which were erroneously placed in the application’s current folder rather than the user-selected folder. [5360]
• Fixed an issue that caused GoldSim to terminate after changing a Time Series element's Data Source from Recording to Locally-defined data. This problem was only observed under the following circumstances: Time Series had no data records and Time Series was referenced using Time Series function. [5361]
• Added ability to filter '\protect' tags from Rich Text Formatted (RTF) data pasted into element notes. The tag causes text to be locked and the note to be applied to any element subsequently selected. [5364]
• Fixed an issue causing inaccurate statistical results when a set of sampled values consists of a continuous distribution with discrete spikes (spikes being caused by repeated sample values). The issue was observed in the Sampled Results distribution type of the Stochastic element and generated statistical results based on Final Value or Time History result values. Assuming a sorted list of sample values, a numerical error is introduced at the first continuous sample value directly following a discrete sample value (spike). The contribution of the sample value is underreported. The error is a function of the difference between the continuous and discrete sample value and can be calculated as follows: (curVal - ((prevVal + curVal) / 2)) * curWeight / 2. curVal=value of first continuous sample, prevVal=value of discrete sample just before curVal, curWeight=sample's weight. [5365]
• Corrected an issue when importing a GSM file as a new SubModel, which may corrupt the model or may prevent the model file from being saved. The issue applies to distribution-type inputs or outputs with an underlying non-scalar data type (e.g. Distribution output of a non-scalar Stochastic element) that references an array label set available in both the imported model and the import destination model. [5368]

Enhancements and Corrections in 11.1.3

GoldSim 11.1.3 is a maintenance release (update 3) of GoldSim 11.1. It was released on September 21, 2015. Enhancements and corrections in this version are listed below:

• Added the capability to create advective and diffusive connections into Source cells [5315]
• Fixed an issue that caused a crash when closing the properties dialog of a hyperlink that no longer had a valid reference [5314]
• Fixed an issue in the Event Delay element where incoming events were not correctly handled while the 'wait for' precedence condition was not satisfied. [5311]
• Time Series function 'lookup' behavior was corrected to reflect any time shifting settings specified on the Time Series element [5310]
• Fixed an issue where input controls of some element dialogs would not mark invalid input expressions as invalid (red background) [5309]
• Fixed an issue where an edited dashboard grid control item label would revert to its original value if you edited value properties without first clicking OK to confirm the label change [5308]
• Fixed an issue where pasting a time history element with reporting periods enabled into a model without reporting periods may generate an error message [5307]
• Fixed an issue where elements in subsystems may update their initial values twice. As a result of this fix, some models may produce different results if there are one or more subsystems with (1) triggered events that trigger when an element output changes or (2) stochastic elements in the static list. In the latter case, stochastics previously sampled twice at time zero will now only be sampled once. Thus, even if a model uses the same random seed, observed sampled values of some stochastics may be different in 11.1.3 and previous versions. [5306]
• Fixed a cosmetic issue where text in read-only grid cells in some CT element dialogs could be deleted or changed by copy/paste [5305]
• Fixed an issue where a long delay could occur when activating a dashboard if it contained several controls [5303]
• Fixed an issue in the History Generator where the 'target' was incorrectly applied when running distributed process if the 'target' varied with time and the 'History Type' was set to 'Random Walk' [5301]
• Modified the Reservoir element to always require lower and upper bound input equations (i.e. the fields can no longer be left blank) even with vector or matrix Reservoirs. [5293]
• Fixed an issue where GoldSim could crash in some circumstances when a Time History result element was opened and realization screening was being used [5292]
• Fixed an issue where hide or disable statuses of dashboard controls were not updated while in pause mode [5290]
• Modified the Time History element 'Disable Element' attribute and Container element 'Enable Time History…' attribute to be editable in the Player [5288]
• Modified the SubModel element properties dialog (including adding an OK button) to allow changes made to the properties in a Player file to persist after closing the properties dialog [5287]
• Modified the Script element to make it possible to paste text into the display units field [5286]
• Fixed an issue in the Extrema Element where reset only worked if the value of the monitored output changed when the reset was triggered [5285]
• Fixed an issue in dashboard output components that could cause GoldSim to crash during memory cleanup [5282]
• Fixed an issue where the text color in a dashboard result display was not retained if a 'frame' border was used [5281]
• Fixed an issue where logical elements (AND, OR and NOT) triggered changed() and OnChanged monitoring functions even if their output values did not change [5279]
• Fixed an issue where changed() and OnChanged functions were triggered by a resampled stochastic even if the value of the stochastic did not change [5278]
• Fixed an issue where a model file could fail to load if an element was serialized that referenced the internal distribution object of a Stochastic that was not yet serialized [5277]
• Fixed an issue where vector initial values were incorrectly applied for information and material delays [5276]
• Improved code used to check equations when models are loaded [5275]
• Fixed an issue in the PDF_CTE function where the function evaluated to an undefined value for a truncated log-normal distribution [5271]
• Fixed an issue where a model might not load if the active modules for the top model and a SubModel were different [5270]
• Eliminated a peculiarity where the background color of an input field would flash pink when a previously invalid input equation was corrected [5269]
• Fixed an issue where an input equation in a sealed container could be edited (without breaking the seal) by inserting a unit, contstant or function by context menu [5268]
• Fixed an issue where inserting a unit, function or constant by context menu in an input field did not trigger a reparse of the expression [5267]
• Fixed an issue were GoldSim could crash after running a model, returning to Edit mode and then unchecking the multiple series option in a Time Series element [5266]
• Fixed an issue where GoldSim could crash if a Reliability Function element had a normal failure mode with 0 standard deviation and a PM replacement failure mode [5265]

Enhancements and Corrections in 11.1.2

GoldSim 11.1.2 is a maintenance release (update 2) of GoldSim 11.1. It was released on November 18, 2014. Enhancements and corrections in this version are listed below:

• Improved performance of Time History results exporting to Excel in cases where calculations are performed in Excel [5263]
• Fixed an issue in Excel data exchange where activating a worksheet could fail (due to a request on the wrong workbook) when multiple spreadsheet elements and files are used [5262]
• Added support to dynamically adjust correlation matrix and preserve  data when editing array label sets (i.e. adding, removing and reordering items) [5261]
• Modified the way in which GoldSim is rescaled for different display resolutions so that windows, text and objects scale proportionally [5260]
• Fixed an issue where GoldSim would delete a custom unit (when saving and closing) if used only in the Excel tab of an importing Time Series element [5259]

• Modified handling of correlation matrix properties such that the correlation algorithm settings are no longer lost when changing the array label set used for the element [5254]
• Fixed an issue where resizing an array label set used by a stochastic or history generator with a correlation matrix could result in a crash [5253]
• Dashboard input grid allowed change to non-scenario data when one or more scenarios had been run. This has been fixed. [5252]
• Fixed an issue where a stochastic that is a sensitivity analysis input could have the wrong value in some circumstances if its distribution input is a function of another output [5251]
• Fixed an issue in the GoldSim Player where it could crash when running a model file without scenarios after a scenario model was previously terminated in the same instance of the Player [5250]
• Fixed an issue where changes to the value of a Data element or the initial value of a Script element were not registered by versioning [5249]
• Fixed an issue where a floating point exception could arise due to an uninitialized buffer used when processing moving averages calculated by an Integrator element [5248]

• Added the capability to display statistical results of a Monte Carlo run using dashboard output controls [#4947]
• Enhanced model options (accessible in the 'Results' tab of the model Options dialog) to allow users (1) to specify a minimum number of significant figures to display in result elements, input fields and tool-tips and (2) to specify a threshold order of magnitude above which results and values should be displayed using scientific notation [#4950]
• Added significant capabilities for (1) accessing and viewing SubModel history and final value results in Time History and Result Distribution elements and also (2) linking SubModel histories to Time Series elements outside of SubModels [#5005]

• Corrected an issue where exporting and importing slave list files did not work consistently [#5178]
• Modified optimization and sensitivity analysis to use deterministic values of stochastics not listed as input variables, rather than using a sampled value when the model is single-realization Monte Carlo [#5177]
• Enhanced GoldSim’s model integrity test by adding the ability to identify and remove elements for which a reference is held by one or more other elements, but that does not actually appear in the model [#5176]

• Corrected an issue where sensitivity analysis for a static stochastic located inside a subsystem container does not work properly [#5172]
• Corrected an issue where a move operation that includes a text box could result in a crash under specific circumstances [#5171]
• Corrected an issue where 'At Etime' and 'At Date' triggers were not handled correctly in an internal clock container (because they referenced the global rather than local clock) [#5169]

• Added an error message to handle the case where an invalid type of discrete change is sent to a Cell element [#5152]
• Modified time labels in the table view of a Time History result element for daily reporting periods to show the standard Windows date format rather than the year followed by "D" and the day of the year. [#5151]
• Corrected an issue where a Reservoir would log an inappropriate warning message when there was no upper bound and the reservoir dropped slightly below its lower bound. [#5150]
• Corrected an issue in many-run simulations (e.g. optimization runs, sensitivity analysis and 'run all' scenario simulations) that could lead to the following error message: "Fatal error in StoreHistory: exceeded number of allocated result-storage files…" [#5149]

• Corrected an issue where an element with a user-defined symbol would not properly reset (in some cases) after selecting the 'Default symbol' option [#4778]
• Corrected a minor UI issue in the RL elements where the Container dialog tabs ('Graphics' and 'Information') were not added after selecting the option to model the component as a system with child elements [#4895]
• Improved pasting options (including context menu paste and Shift-Insert) in input grid cells in Selector, Splitter, Allocator and Random Choice elements [#4969]
• Corrected issue where data could be pasted into some sealed elements and the data would remain without breaking the seal [#4989]
• Default names for Result Elements were changed to the following: "History 1", "Distribution 1", "Multivariate 1" and "Array View 1" [#5072]
• Corrected an issue where opening a Time History element connected to a SubModel and with one outer model realization could lead to a crash. [#5075]
• Corrected an issue where 0/0, in some instances, is not evaluated to 0 and instead leads to a fatal error [#5081]
• Modified spreadsheet element pre-import (i.e. during Edit mode) behavior so that it occurs even if results are saved to the Excel file [#5082]
• Made minor UI changes to reduce flicker in Result element displays, tool-bars and buttons when resizing [#5086]

Corrections in 11.0.5

GoldSim 11.0.5 was released on January 21, 2014. Corrections since GoldSim 11.0.4 are listed below:

• Corrected an issue with the CT Pipe element that led to erroneous results when using suspended solids [#5110]

Corrections in 11.0.4

GoldSim 11.0.4 was released on January 17, 2014. Corrections since GoldSim 11.0.3 are listed below:

• Elements added in a cloned container are now added at the same position in the graphics pane in the sibling container [#4630]
• Corrected an issue where the values or properties of a cloned element whose sibling is in a locked container could be changed. [#4780]
• Corrected minor issues with axis settings in Multi-Variate and Time History result elements [#4797, #4919]
• Made improvements to the input table for a Sampled Results Stochastic [#4983]
• Corrected an issue where the TBL_Inv_Integral function is undefined if the dependent variable of the table is constant [#5083]
• Corrected and improved the handling of Reservoir calculations when the reservoir is at its bounds [#5084]
• Corrected an issue where the expected value of an IF expression with array type arguments cannot be evaluated. [#5085]
• Corrected an issue where the time component of a date-time value is dropped when the model is opened. [#5089]
• Modified run log dates to show milliseconds in addition to hours, minutes and seconds [#5090]
• Corrected an issue where GoldSim improperly cleans up after a Time Series element whose definition is exposed from a SubModel is deleted. This prevented the model from being saved. [#5095]
• A simulation run is now prevented in CT models if an atomic weight is less than or equal to 0 [#5097]
• Added the capability to view the run log for the previous run in Edit mode. The run log is not available in or after leaving Scenario mode and is not saved with the model file. [#5099]
• Corrected some issues in the Time Series element that allowed the element to be placed in an inconsistent state that could cause GoldSim to crash [#5100, #5105, #5108]
• Corrected an issue where copying and pasting a result element inside of a SubModel invalidated any result items [#5103]
• Corrected an issue in the Lookup Table element that could lead to an inconsistent internal state in the element and prevent models saved with such an element from being re-opened.  [#5106]
• Corrected an issue with the CT Pipe element that led to erroneous results when using suspended solids [#5109]

Corrections in 11.0.3009

GoldSim 11.0.3009 was released on December 17, 2013 to address the following issues:

• A Reservoir element can overshoot a bound due to round-off. If a Reservoir element overshoots a bound slightly, due to round-off, the overshoot is not corrected until its Update.  In models that have recursive loops other elements that reference the Reservoir may be Updated prior o it, and may see the value that lies outside of the Reservoir's bounds. [#5084]
• User-defined dates in input expressions drop the (optional) time component upon loading of the model file. Example: A date-time defined as “Dec-17-2013 6:00 PM” changes to “Dec-17-2013”. The issue has been corrected. [#5089]
• Error when calculating the conditional argument in array-type IF statements. [#5085]
• TBL_Inv_Integral function is undefined if table dependent variable is constant. [#5083]

Enhancements and Corrections in 11.0.3

GoldSim 11.0.3 was released on November 4, 2013.  Some of the most notable corrections since GoldSim 11.0.2 are listed below:

• Imports from spreadsheets were modified in two significant ways:
  • If an element imports from a spreadsheet, and the spreadsheet file is not found, GoldSim will continue to carry out the simulation using the last values that were imported.  A message is written to the run log if this happens.
  • If an element imports from a spreadsheet, and does not export to that spreadsheet, the information is imported prior to starting the simulation.  This allows models that use distributed processing to not have to transmit the spreadsheet files to the Slave processors.
• A bug was fixed where an if-test on an array-type argument can give erroneous results.  This can only occur if the second argument to the if-statement is a complex expression, not a simple link to an output.
• A bug was fixed where the OnChanged trigger type may not register the first change of the monitored output if its initial value is zero.
• A bug was fixed where if a Material Delay element has an 'Initial Outflow' rate defined the calculated outflow rate at time 0 may be incorrect.
• A bug was fixed where an RT-module model crashes when looping decay chains are defined.
• A bug was fixed where an RT-module model using a Pipe element occasionally crashes with an invalid floating-point exception.

 Enhancements and Corrections in 11.0.2

GoldSim 11.0.2 was released on September 5, 2013.  Some of the most notable corrections since GoldSim 11.0 are listed below:

• Support pasting of Time Series data with more than 65,535 records.
• Corrected various runtime issues that would cause GoldSim to hang or crash during simulations of SubModels.
• Corrected various issues with Time Series elements (updating, editing of time shifting options, data import from Excel, wrapping of 365 day records).
• Corrected calculation of Reservoir element with initial value starting below lower bound.
• Clarified simulation requirements for Optimization and Sensitivity Analysis runs.
• Addressed issues when editing array data styles, including loss of defined style when editing the Species element.
• Improved performance of Dashboard output control updates and refresh rates.
• Corrected editing problem in Milestone element.
• Corrected a problem in the Excel Import/Export Wizard that caused GoldSim to crash.
• Improved calculation of Material Delay.
• Improved resetting of history chart zooming and reset of custom zoom levels.
• Revised and improved logic for handling ‘At Stock’ triggers.
• Improved legend and labels in history charts.
• Corrected problems in containment and class view browsers that could cause GoldSim to crash when element sub items are shown.
• Corrected calculation and representation of ‘All Results’ display type in nested Monte Carlo Distribution results.
• Revised logic for storing grid control based scenario data.
• Improved CPU benchmarking for elements in SubModels.
• Corrected structural issues on SubModel input interface that would treat such value as not static.
• Minor user interface corrections.

New in GoldSim 11

GoldSim 11 was released on July 22, 2013.  It is a major new version and introduces numerous new features and capabilities to GoldSim, as well as many enhancements and corrections. For an overview of new features and changes, please refer to document GoldSim 11 Summary.pdf. A link is available in the GoldSim 11 program group in the Windows start menu.

Some of the most notable new features and capabilities are listed below:

• The compression algorithm for inserted (or pasted) images was improved allowing for smaller file size with similar quality.
• The Time tab of the Simulation Settings dialog has been completely redesigned to provide more intuitive and powerful tools for defining the timestepping options.
• Time History Results and the Simulation Settings have been modified to prevent unnecessarily creating large result files.  The most noticeable change in this regard is that for multiple realization (Monte Carlo) runs, time history results are only saved for outputs that are connected to Time History Result elements.
• Run Properties (e.g., ETime, DayOf Week, etc.) have been redesigned to provide more intuitive and powerful tools for referencing these important properties. 
• A powerful new capability that allows you to create, run and compare different scenarios for your model has been added.  Scenarios are differentiated by having different sets of input data.  In particular, different scenarios have different values for one or more Data elements (referred to as Scenario Data).  GoldSim’s scenario modeling capability allows you to directly compare results generated by different sets of input parameters.  In effect, when you use this capability, your model can store (and subsequently compare) multiple sets of outputs.
• The entire result display framework has been updated. This includes that ability to create Reporting Periods, allowing yopu to compute and report accumulated,  average, the change or the rate of change values over a specified period (e.g., monthly, annually).  You can also view “unscheduled timesteps” in time history displays.
• All results that are being plotted can be assigned custom labels (that can have spaces, unlike element and output names). 
• Several new Dashboard features, including:
  • A new Button command (“Refresh all Spreadsheet outputs”) that imports all outputs from linked Spreadsheet elements into your model.
  • A new Button command (“Export Simulation Results”) that executes a global export of available results from Time History Result elements that are specified to export to spreadsheets and/or text files.
  • A new control (the Text Result control) that allows you to display one of a series of user-specified text strings based on the value of an output (e.g., if the value is less than 10, display “Low”, if the value is between 10 and 30 display “Medium”, and if the value is greater than 30 display “High”).
  • A new Scenario control allows Player users to create, run and compare scenarios.
  • The ability to navigate directly to a Dashboard within a SubModel.
• Unlike other elements in GoldSim, the names of Result elements and Dashboards can now contain spaces.
• An option for an Integrator to compute up to three different moving averages.  A moving average is a uniformly-weighted average of the Rate of Change over a specified averaging time. It is calculated as the change in the value of the Integrator over the averaging time divided by the averaging time.
• Four new functions that can be used to manipulate Lookup Tables (including the ability to carry out a reverse lookup)
• Three new types of trigger types (that can be used in all triggering dialogs).
• The ability to reference a value from a Time Series element at some point in the future or past (as opposed to at the current time in the simulation). 
• Two new array functions that can be used to create dynamic lookup tables (in which the values for the independent and/or dependent variables are changing with time). 
• Several improvements to the Stochastic element, including:
  • Two new distribution: BetaPERT and Log-Cumulative.
  • The ability to use the Spreadsheet element to import a probability distribution from a spreadsheet.
  • An additional output (the Distribution definition).  This output is a complex output representing all the distribution information.  GoldSim provides several specialized functions that can be used to reference the Distribution output type and return properties of the distribution. For example, the function PDF_Mean(X) returns the mean of Distribution X; the function PDF_Value(X, 0.95) returns the 95th percentile.
  • An advanced feature for dynamically revising distributions during a simulation using “simulated Bayesian updating”.
• Support for nested Monte Carlo simulation.
• New features to facilitate modeling of aging chains.
• The spreadsheet and text file export from time History Result elements has been changed in order to support new time history features (e.g., Reporting Periods, scenarios).
• Support for the.XLSM macro--enabled Excel format.
• The ability to reset the Extrema element.
• If both the numerator and the denominator of an expression are zero, GoldSim will no display a fatal error; instead, the resulting expression will be set to zero and the simulation will continue.  This can be very convenient, as it allows you to avoid adding complex logic to check for such cases.
• New features to make it easier to quickly reference exposed outputs of localized Containers within input fields of other elements. These features also make Containers act like objects with a custom output interface.
• Improvements to the Milestone element.
• Improvements to time shifting options for Time Series elements.
• Changes to how user-defined units are managed.
• The ability to log CPU time for External, Script and Spreadsheet elements.
• An option (within the RT Module) to utilize a large built-in database of radionuclide decay data (species, decay rates and daughter products).  In particular, the feature allows you to view over 1200 radionuclides (along with their corresponding stable elements) and to selectively include some of these radionuclides in your simulation. The data is based on the International Commission for Radiation Protection (ICRP)’s Publication 107.
• Improvements to the Aquifer element.
• Improvements to how Cells manage changing media quantities.

Release Notes GoldSim 10.5

Enhancements and Corrections in 10.5 SP7

GoldSim 10.5 SP7 is a maintenance release of GoldSim 10.5. GoldSim 10.5 SP7 was released on March 3, 2016. 

• Corrected an issue that prevented GoldSim Player from saving the model file using the 'Save' or 'Save as' menu. [5374]
• Corrected an issue causing GoldSim to not recognize a valid license on some non-English operating systems. [5375]

Enhancements and Corrections in 10.5 SP6

GoldSim 10.5 SP6 is a maintenance release of GoldSim 10.5. It was released on February 12, 2016. 

• This release of GoldSim introduces a powerful and flexible licensing system. Detailed information is provided in the GoldSim Licensing End-User Manual, which can be found in the GoldSim installation folder (GoldSim_Licensing.pdf).
  Note: The new licensing system is simultaneously introduced for GoldSim products 10.5, 11.0 and 11.1. Updates supporting the new licensing system are available on our website. [5347, 5355]

Enhancements and Corrections in 10.5 SP5

GoldSim 10.5 SP5 was released on September 27, 2013.  GoldSim 10.5 SP5 is a cumulative update (includes all improvements and corrections found in earlier 10.5 service packs).

• A new feature in GoldSim 10.5 SP4 was found to sometimes cause errors in models with diffusive flux links and very long timesteps.  In some cases GoldSim would skip doing solubility calculations for some Cell elements (a warning message would be written to the run log if this occurred).  This message is appropriate for very rapidly flowing advectively-dominated Cells, but should not occur for diffusive systems.

Enhancements and Corrections in 10.5 SP4

GoldSim 10.5 SP4 was released on June 28, 2013.  GoldSim 10.5 SP4 is a cumulative update (includes all improvements and corrections found in earlier 10.5 service packs).

The most important issues corrected in GoldSim 10.5 SP4 are listed below:

• The compression algorithm for inserted (or pasted) images was improved allowing for smaller file size with similar quality.
• 3d-charts of Array View results can be printed.
• Corrected an issue causing the quality of inserted images to decrease over time.
• Corrected a severe issue involving chart styles that may cause corruption of the model file.
• Corrected an issue that may have caused the importance-sampled realization weights to be incorrect during distributed-processing simulations.
• Corrected a problem in IF-statements causing GoldSim to crash if the IF-condition involved a complex equation and arrays.
• Corrected a problem in the Stochastic element that may cause GoldSim to crash when editing the ‘Correlated To’ option.
• Corrected the name of the built-in Swedish currency (Krona).
• Corrected several issues related to the use of MS-Excel spreadsheets for data import and export, or a function.
• Corrected incorrect calculation in Material Delay elements located inside looping Containers.
• Corrected a runtime error (access violation) in recording Time Series element of a static model.
• Corrected a problem in recording Time Series elements in looping Container, which may have recorded duplicate values.
• Corrected a sequencing problem with recording Time Series elements which may have caused the recording of the previous rather than the current value of the selected output.
• Corrected a problem in the Splitter element outputting negative amounts.
• Corrected an issue that prevented container-type elements to be inserted into cloned systems.
• Corrected a problem in the Slider control on Dashboards; the current value was not correctly shown for vertical sliders.
• Corrected a problem in the Yucca database format involving 2d-tables.
• Corrected a problem in Spreadsheet elements when selecting an output located inside a localized Container. The selected output was not automatically exposed.
• DP Module: Corrected a problem that may have left a model stuck in Run Mode after a failure to launch a distributed processing simulation.
• CT/RT Module: Corrected problems with built-in array label sets. Upon disabling the CT/RT module these sets are kept in a model if they are referenced by non-CT/RT elements. However, in previous versions the sets were not subsequently marked as user-defined. As a onsequence, the sets could not be edited, removed and the CT/RT module could not be re-activated.
• CT/RT Module: A memory corruption issue and subsequent crash of GoldSim was fixed in cloned Fluid elements.
• CT/RT Module: Corrected problems that would stall a simulation when very fast turnover cells applied solubility limits or when solving congruent dissolution for extremely low solubility levels.
• RL Module: The advanced failure mode option ’repair to specified age’ was corrected.
• Includes additional general performance and stability improvements.

Enhancements and Corrections in 10.5 SP3

GoldSim 10.5 SP3 was released on September 28, 2012. GoldSim 10.5 SP3 is a cumulative update (includes all improvements and corrections found in SP1 and SP2).

The most important issues corrected in GoldSim 10.5 SP3 are listed below:

• In previous versions, an error was found related to changing the members of an array-label set that is used to define the rows or columns of a matrix. In particular, the error occured when: 1) A reference had been made to a row, a column, or a single item within a matrix-type output, using an expression such as: “M[Friday, *]” (which would reference the ‘Friday’ (sixth) row in a matrix), and 2) subsequently the array-label set was edited so that the referenced row or column has a different ordinal value.  This would happen, for example, if an earlier entry in the set (e.g. ‘Thursday’) was deleted. When this happened, the originally-referenced row or column number (i.e., 6) was not automatically corrected to reflect its new value.  If the original row or column number was still valid then the model would still run, and would give incorrect results, as the wrong row or column would be accessed. This problem was corrected in SP3.
• Improves usability and access to status information about floating licenses.
• Adds ability for Script element to break (initiate debugging) on Break and Continue statements.
• Adds support for dates on axes of multi-variate charts.
• Corrects several problems with dashboard controls including issues with dynamically enabling/disabling or showing/hiding controls, tab order and setting/removing the focus.
• Corrects a problem with the Date-Time dashboard control.
• Improves data type checking capabilities when routing Time Series data through SubModel interfaces.
• Corrects several problems and improves stability and performance related to exporting Time History results to spreadsheet files.
• Improves result accuracy for very fast transport in Aquifer elements. Corrects memory consumption issues with Aquifer elements during distributed processing simulations.
• Corrects several problems related to sub items (inputs, outputs) when shown in main browsers (containment and class view).
• Improves precision of Time Series lookup value when outputting the average value of the next time step.
• Corrects Table element issues when importing data from spreadsheets and when changing unit dimensions.
• Corrects issues causing GoldSim to terminate when changing the size of an indexed array label set.
• Fixes a result memory issue when running optimizations.
• Corrects several problems with cloning CT elements and enhances detection of invalid cloning requests during paste and move operations.
• Includes additional general performance and stability improvements.

Enhancements and Corrections in 10.5 SP2

GoldSim 10.5 SP2 was released on September 22, 2011. GoldSim 10.5 SP2 corrects a number of issues with GoldSim 10.5 SP1.

The most important issues corrected in GoldSim 10.5 SP2 are listed below:

• Problems that could lead to a model’s file size becoming larger every time the model is loaded into memory were identified and corrected.
• Numerous minor issues with the user interface were corrected.
• The CT Module’s new Aquifer element now applies its ‘Initial inventory’ at the ‘front end’ of the pathway.  Previously it was distributed uniformly over the pathway length.  Also, its ‘cumulative input’ boundary condition was not being handled correctly, and this has been corrected.
• The CT Module’s Source element could occasionally not release 100% of its inventory, when the model had very long time steps.

Enhancements and Corrections in 10.5 SP1

GoldSim 10.5 SP1 was released on April 13, 2011.  GoldSim 10.5 SP1 introduces a few new features and corrects a number of issues with GoldSim 10.5.

• A new math function, vIndex(vector, value) has been added. It searches for a specified value within the provided vector, and returns the index value at which the value is found.  It treats the vector as a continuous function, interpolating where necessary between the defined points in the vector, and as a result the returned index value may have a fraction.  For example, if the vector’s values were <3, 4, 5, 6> then vIndex(vector, 5.1) would return an index value of 3.1.
• A new math function, vInterp(vector, index) has been added. It interpolates into the vector using the specified index value.  For example, if the vector’s values were <3, 4, 5, 6> then vInterp(vector, 3.1) would return a value of 5.1.
• These functions will frequently be used in conjunction, for example vInterp(vector2, vIndex(vector1, v)) will look up the location of v in vector 1 and return the corresponding value from vector2.
• Dashboard components can now be configured to be dynamically disabled or hidden based on any model output. This allows for more customizable dashboard user interface.
• The new Aquifer element had a number of problems corrected, including access violation errors when run in distributed processing mode, erroneous reporting of the mass in the pathway when decay chains are involved, and erroneous discharges when its length was shortened during the simulation.
• Contaminant transport models that incorporated “Air” Cell pathways could occasionally crash.
• Result tables would not sort correctly when displayed using certain European number formats.
• Old vector-type Stochastic elements only used Latin hypercube sampling for the first array item.
• User-defined dates within expressions are now automatically converted to the correct local date format when viewed on a computer with a different region setting.
• When date-type results are exported to Excel or text files they now user the correct local date format.
• The chart keyword %x_unit% now respects the unit definition of the distribution result.

New in GoldSim 10.5

GoldSim 10.5 was released on December 21, 2010.  GoldSim 10.5 introduces a number of new features and capabilities to GoldSim.

In addition to these Release Notes, a more detailed document that summarizes the major new features in GoldSim 10.5 is provided in the Start Menu (under All Programs | GoldSim 10.5 | Version 10.5 Summary).  It is strongly recommended that all existing GoldSim users read this document!

Enhancements and corrections in this version are listed below:

• A major new feature, the Script Element has been added. Iterative calculations, complex array manipulations, and other highly customized calculations, many of which could only have been previously done using an External (DLL) element, can now be built directly into GoldSim as a procedural Script without any external programming.
• GoldSim 10.5 includes another new element, the Aquifer Pathway for the CT/RT Module. An Aquifer pathway combines the features of a Cell and a Pipe element, and provides a way to simulate processes such as vertical transport through an unsaturated (vadose) zone, and horizontal transport in aquifers, rivers, channels and pipelines.
• Date/time simulations can now extend over a much broader range: 1 January 1700 to 31 December 9999. GoldSim 10.5 also includes other enhancements for plotting time history results involving dates.
• When editing an input field, GoldSim automatically suggests the names of existing outputs at the bottom of the input field.
• GoldSim 10.5 supports the extended worksheet ranges (1,048,576 rows by 16,384 columns) introduced in Excel 2007.
• If statements can handle mixtures of Arrays and scalars.
• The Time Series elements now include a new representation: Changes and constant values over the previous interval.  These options make it easier to import measured time series data, as that is the manner in which it is often actually recorded (i.e., a change or an average value ver the previous time interval).
• The GoldSim Units Manager has been redesigned.
• Lookup Tables now support an option to be linked to a text file.  The text file data is imported automatically whenever the data in the file is modified.
• GoldSim 10.5 provides powerful tools for both exploring and manually changing the causality sequence.
• Performance improvements when simulating large, complex models.
• Performance improvements in communication with MS-Excel.
• Simplified array constructors (deduce array label set automatically).
• Use of up to 32 slaves per client computer when using the DP-Plus Module.

Release Notes GoldSim 10.11

Enhancements and Corrections in 10.11 SP4

GoldSim 10.11 SP4 was released on August 26, 2010.  GoldSim 10.11 SP4 is a minor upgrade which corrects problems found in GoldSim 10.11 SP3:

• Fixed a bug where CT-module solutions for Cell elements can cause a GoldSim crash.
• Two other changes in GoldSim 10.11 SP4 were to correct minor problems:
  • A problem using assisted registration when using the floating license manager.
  • SubModels were unable to handle durations longer than 68 years.

Enhancements and Corrections in 10.11 SP3

GoldSim 10.11 SP3 was released on July 27, 2010.  GoldSim 10.11 SP3 is a minor upgrade which corrects problems found in GoldSim 10.11 SP2:

• Fixed a bug where CT-module solutions for Cell elements can cause a GoldSim crash.
• All other changes in GoldSim 10.11 SP3 were to correct minor problems, including the following:
  • A number of minor issues in the reliability (RL) module.
  • A recording Time Series element would not correctly capture its results when run using the distributed processing option.
  • Importing data from a corrupted Excel file could cause GoldSim to crash.

Enhancements and Corrections in 10.11 SP2

GoldSim 10.11 SP2 was released on June 18, 2010.  GoldSim 10.11 SP2 is a minor upgrade which corrects some problems found in GoldSim 10.11 SP1:

• Fixed a potentially important bug involving available properties. An input that references a run property or an available property may not correctly switch to a closer property of the same name when such a property becomes available. For example: Assume Expression A is inside a container C and references run property Day. That is, a link exists from the Model container to A. Then container C is changed so it is an Internal Clock sub system. This introduces several new available properties at C that should "override" the same names at higher hierarchical levels (i.e. Model). The problem was that Expression A would stay connected to the Day property of Model, instead of automatically connecting to the Day property of C when the property was introduced there.
• All other changes in GoldSim 10.11 SP2 were to correct minor problems, including the following:
• Saving time histories in models that contain optimizing sub-models.
  • Fixing a problem for Previous Value elements within looping containers in static models.
  • Fixing a problem when exporting time history results to a spreadsheet after running a distributed processing simulation.
  • Fixing minor problems with reliability elements and with simulating resources.
• Improved the solution efficiency for contaminant transport models.  Run-times are significantly reduced in GoldSim 10.11 SP2.

Enhancements and Corrections in 10.11 SP1

GoldSim 10.11 SP1 was released on April 2, 2010.  GoldSim 10.11 SP1 is a minor upgrade which corrects some problems found in GoldSim 10.11:

• When exporting time history results to Excel spreadsheets, the user can incorporate keywords %curtime%, %runtime%, %curdate%, and %rundate% into the file name of the Excel file.  These keywords refer to the time and date of the actual simulation model run.  Previously, only %curtime% and %curdate% were supported, and they referred to the actual time and date that the Excel file was being created.
• All other changes in GoldSim 10.11 SP1 were to correct minor problems, including the following:
  • Errors if exporting time history data to a sheet that did not exist, or if multiple Time History elements targeted the same sheet.
  • Issues with SubModels using the CT/RT modules.
  • Issues with annual periodicity when shifting Time Series to match the simulation’s time settings.

Enhancements and Corrections in 10.11

GoldSim 10.11 was released on February 25, 2010.  GoldSim 10.11 is a minor upgrade consisting of several minor new features, as well as bug fixes and some computational improvements.

The most important changes in GoldSim 10.11 are as follows:

• Within 2D and 3D scatter plots, it is now possible to divide the realizations into different classes, with each class displayed in a different color (and/or symbol). A class is simply defined by a condition (e.g., A > B).
• Two new vector functions were added in GoldSim 10.11.  These functions can be used to sort the values in ascending or descending order in a vector.
• Numerous minor improvements and cosmetic changes were made to the Resources feature that was introduced in GoldSim 10.1.
• The Spreadsheet element was improved to make initialization more efficient (will be particularly noticeable with models with hundreds of Spreadsheet elements).
• Fixed a bug that prevented GoldSim Pro users from accessing Reliability elements (GoldSim Pro users should be able to insert up to 10 Reliability elements without having the full Reliability Module activated).
• A bug related to accessing Lookup tables near their upper or lower bounds that could cause GoldSim to crash was fixed.
• The ~Remainder locally available property in Allocator elements was not being correctly calculated.  This has been fixed.
• A memory leak that could cause GoldSim to crash when working with a complex file for long time periods was fixed.

New in GoldSim 10.1

GoldSim 10.1 was released on January 11, 2010.  GoldSim 10.1 introduces a number of new features and capabilities to GoldSim.

In addition to these Release Notes, a more detailed document that summarizes the major new features in GoldSim 10.1 is provided in the Start Menu (under All Programs | GoldSim 10.1 | Version 10.1 Summary).  It is strongly recommended that all existing GoldSim users read this document!

The most important changes in GoldSim 10.11 are as follows:

• Resources can now be modeled in GoldSim.  The user can define one or more Resource Types, and specify locations in the model where Stores of the different Resource Types exist.  Various elements can have specified requirements for Resources, and will automatically wait for Resources to be available before carrying out their activities.  Resources are typically used to represent things such as funds, spare parts, fuel, equipment, or personnel.
• Time Series elements have been significantly enhanced:
  • They can contain multiple time series data sets, and the user can control which data set is used for a given model simulation or realization.
  • They can import data sets from existing GoldSim model files that are in result mode.
  • They have options to allow shifting the time base of their stored histories to match the requirements of the current simulation. 
• Array outputs can be directly accessed with arguments that can be functions of time, for example “”Array[X + 2 * Time |yr|].
• User-defined Table functions can be applied to an entire array at one time.
• Logical operators, min(), max() and mod() can process arguments that are a combination of arrays and scalars, e.g. “max(Array, 3)”
• User-defined dates in input fields are automatically converted to the date format set for their Windows computer.  This allows a model built in one country to be run in another country with no conversion issues.
• Discrete Change Delay elements can specify that their delay time as a function of the signal that is being delayed.
• Discrete Change Delay elements can require resources in order to process signals, can specify individual delay times for individual signals, and can queue up incoming signals that are not ready to process.
• Command-line options allow a user to directly change model input data and to run sets of simulations from a batch file.
• Reliability Module elements can automatically import failure mode definitions from a spreadsheet, can export reliability to a spreadsheet at the end of a simulation, and can require resources in order to operate or be repaired.
• Reliability Module elements can simulate reliability-centered maintenance (RCM) by selectively triggering repairs of aging components during a PM.
• Reliability Module element can now have custom outputs.  This makes it much easier to use the elements to directly output key results such as throughput.
• Contaminant Transport Module Source elements can simulate waste inventory exposure due to congruent dissolution of a waste matrix that itself is dissolved and transported within the model.
• Enhanced Latin hypercube sampling options allow the user to control sampling sequences for SubModels, and to choose mid-point or random-point sampling for LHS strata.
• Within array constructors, row and col variables are interpreted differently from previous versions.  In previous versions, row and col always referred to the ordinal row or column number.  They now refer to the actual row or column label (for labeled sets, they necessarily still refer to The ordinal row or column number).
• Within Allocators, you can specify how demands with equal priorities are treated. The can be shared equally (as in previous versions), or shared proportionally to the demands.
• Reservoirs now have a new state variable outputs (called Is_Full) that reports True if the Reservoir is at its upper bound.
• Several new navigation features were added to Dashboards.
• Switching between Dashboards in the Player is now faster.
• In previous versions of GoldSim, if you modified the graphical properties of the influences connecting elements (e.g., changed the shape or color) and then copied and pasted (or moved) the Container in which those influences were located, the graphical properties were lost. In GoldSim 10.1, these properties are preserved in the new (pasted) Container.

Release Notes GoldSim 10

Enhancements and Corrections in 10.02

GoldSim 10.02 was released on September 15, 2009.  GoldSim 10.02 fixes a number of bugs in GoldSim 10 SP2 (and earlier GoldSim versions). More importantly, it makes some modifications to GoldSim’s Latin Hypercube Sampling algorithm, as well as the manner in which nested Monte Carlo (probabilistic SubModels) are treated.  These changes are not described in the Help documentation (this will be updated in the next major release).  Rather, they are described in a PDF document that is installed with the software.  The document can be accessed via the Start Menu (under All Programs | GoldSim 10 | GoldSim 10.01 Summary). 

Additionally, GoldSim 10.02 corrected a bug in 10.01 that affected the CT/RT module.  If Cell elements used time-varying amounts of media, and no other properties of the Cells changed with time, the changes in the media amounts would be only partially captured by GoldSim.

Enhancements and Corrections in 10.0 SP2a

GoldSim 10 Service Pack 2 was released on April 29, 2009.  GoldSim 10 SP2 fixes several potentially significant bugs in GoldSim 10 SP1 (and earlier GoldSim versions), and also addresses some minor issues.

• A Timed Event Generator that uses the “Remaining time until event” option can emit a spurious second event in the time step following the planned event.
• The GoldSim Player cannot open files that were previously saved by the Player.
• The Convolution element does not require correct units for the transfer function definition.
• Under some circumstances a Material Delay element can produce ‘noisy’ outflow rates.  The total amount released is still correct.
• Under rare circumstances a Cell element with an extremely small amount of water present can cause a floating point overflow.

GoldSim 10 Service Pack 2a was released on July 23, 2009.  GoldSim 10 SP2a fixes no bugs in GoldSim; in fact, the GoldSim binary files, including the executable files, were not changed at all.  Instead, GoldSim 10 SP2a adds some runtime system and licensing files that need to be present on certain computers in order for the GoldSim application to launch and run.  If GoldSim 10 SP2 is launching and running on a given computer system, there is no need to install GoldSim 10 SP2a.

Enhancements and Corrections in 10.0 SP1

GoldSim 10 Service Pack 1 was released on March 11, 2009.  GoldSim 10 SP1 fixes three potentially significant bugs in GoldSim 10, and also addresses some minor issues that can arise when editing a model file.

• If a Sum element’s value goes to zero, affected elements may not reflect this change.
• If a CT-Module pathway element experiences a change in an advective outflow rate, under certain circumstances it will not incorporate this change.
• When adding elements, under certain conditions (e.g., if the graphics pane was scrolled down or zoomed out), the element could be inserted in the wrong location (i.e., different from where the cursor was placed when right-clicking to insert the element).

New in GoldSim 10

GoldSim 10 was released on February 18, 2009.  GoldSim 10 includes a large number of major enhancements, as well as a significant number of general improvements and minor bug corrections to GoldSim 9.60 in order to improve performance and stability.

In addition to these Release Notes, a more detailed document that summarizes the major new features in GoldSim 10 is provided in the Start Menu (under All Programs | GoldSim 10 | Version 10 Summary).  It is strongly recommended that all existing GoldSim users read this document!

Major Features and Improvements to the GoldSim Framework:

• An optional user-defined password can be used to protect a model file.
• A large number of changes have been implemented to improve the performance of GoldSim, particularly when editing and manipulating large models.
• Tool-tips for elements now provide a substantial amount of information (previously, they only displayed the name, description and the value).  This allows you to better explore and understand a model without having to open dialogs.
• The expression editor in GoldSim has been significantly improved (enhanced error handling, improved tool-tips to facilitate debugging).
• GoldSim 10 supports both .xls and .xlsx Microsoft Excel files.
• A stair-step option (i.e., no interpolation is applied) is now available for Lookup Tables.
• The correlation algorithm for Stochastics has been significantly enhanced.  This includes the ability to define a correlation matrix for Stochastic vectors.
• You can now specify a percentile level for a Stochastic.  When you do so, GoldSim uses the value corresponding to the specified percentile.  Among other things, this can be used to force a particular correlation scheme.
• The Latin Hybercube sampling (LHS) algorithm has been modified to provide a stratified LHS, where subsets of the total set of realizations also represent LHS strata.
• The Importance sampling algorithm for Stochastics has been enhanced.
• Five new distributions are now available (Beta using success/failure, Extreme Probability, Extreme Value, Pearson Type III, Sampled Results).
• An Event Importance Sampling capability has been added to facilitate efficient simulation of low-probability, high-consequence events.
• The Selector dialog has been modified to make it easier to create and view the switches.
• Cloned elements are now graphically identified in the graphics pane.
• Several powerful new vector and matrix constructor capabilities have been added.
• Conditional Containers have been modified to better support project planning simulations.
• Time Series elements have been enhanced to facilitate modeling multiple scenarios.
• GoldSim can now run on 64-bit Windows operating systems. 64-bit native DLLs are also supported for External and External Pathway elements.
• You can now copy and paste multiple elements (previous versions only supported copying and pasting of elements one at a time).
• The licensing system was streamlined to make it more stable, improve assisted registration, and make it easier to switch between floating and standalone licenses.
• The Note Pane has been modified to provide a cleaner interface and full RTF formatting capabilities.
• The Discrete Change Generator element has been modified to allow users to force a specific sequence of operations when causal loops are involved.

Contaminant Transport Module Enhancements and Changes

GoldSim 10 includes a number of significant enhancements to the Contaminant Transport Module:

• A new array label set (Elements) is available.  This allows you to enter Fluid and Solid properties (e.g., Solubilities, Partition Coefficients) on an elemental, rather than species basis.
• The Source element has an option to provide a uniform degradation rate of a waste matrix over a specified time period.
• Solubilities can now be entered in terms of either mass/volume or moles/volume.
• All Pathway elements now allow you to specify boundary conditions with either Initial Conditions or Contaminant Input Rates.
• The Cell Pathway allows you to specify a Defined (fixed) Concentration boundary condition.
• Negative flow rates are now allowed between Cell elements (a negative Outflow is treated as a positive Inflow).
• Powerful new capabilities have been added to facilitate simulation of diffusion through partially saturated porous media.
• The Plume function now accepts vector arguments.
• Numerous enhancements have been made to the CellNet Generator.
• An advanced solid property has been added to allow you to specify that suspended particulates may move at a different velocity than the advecting fluid.
• Modifications have been made to the Contaminant Transport Module solution algorithm to better support coupled flow and transport models.

Reliability Module Enhancements and Changes

GoldSim 10 includes a number of significant enhancements to the Reliability Module:

• Several new outputs have been provided for Reliability elements.  The most important of these is the Failed output, a vector that provides the status (failed/unfailed) of every failure mode.
• Modifications have been made to the Status output of Reliability elements.  Existing users should note that this could potentially change the behavior or some models, so it is critical that you read about these changes in the Summary document.
• Failure modes are now treated as Internal Requirements.  This has the advantage of allowing you to define failure modes that are non-fatal.
• The Results tab for Reliability elements has been redesigned.
• An Importance Sampling capability has been added to Reliability elements to facilitate efficient simulation of low-probability, high-consequence failures.
• Improvements have been made to better support simulating internally handled Actions.

Distributed Processing Module Enhancements

Two important improvements were made to the Distributed Processing Module:

• You can now specify that multiple realizations are sent (at the same time) to each Slave.  This is valuable in situations when the Slave communication process is the bottleneck (e.g., running a large number of quick realizations).
• If a distributed processing run is halted, the Master now provides an option to resume the simulation.

Dashboard Authoring Module Enhancements

One of the more significant sets of enhancements included in GoldSim 10 are changes to the Dashboard Authoring Module. The most important of these are listed below.

• You can now control the size of the Dashboard window in the Player, and if this is smaller than the Dashboard itself, the Dashboard supports scrolling.
• You can now copy and paste Dashboard elements and individual Dashboard controls.
• You can now toggle between an Active and Design View when viewing a Dashboard in Edit Mode within GoldSim.
• The Edit control has been updated such that any entered values are immediately recognized and validated (previous versions required you to press Enter or change focus). In addition, you can choose to force the value to be a multiple of a particular increment.
• Improved alignment tools have been provided to help you to design your Dashboards.
• You can now set the Tab Order for all controls in a Dashboard.
• The Checkbox control has been updated to allow, among other things, a label and a default value.
• The button control has been updated.  Additional button options include an option to edit a lookup table, and to select a new spreadsheet to link to for a Spreadsheet, Time Series, or Lookup Table element.
• The Slider control has been updated such that can choose to force the value to be a multiple of a particular increment.
• A new Date-Picker control has been added to allow you to enter dates directly on a Dashboard.
• List and Combo Box controls have been added to allow you to select one value from a list of values.
• A new Grid control has been added that allows you to create a grid of controls.  The grid cells can be made up of scalar, vector or matrix Data elements, and can be Edit Boxes, Check Boxes or Combo Boxes.
• A new Status output control has been added that allows you to display a specified image on the Dashboard based on the value of an output (e.g., show a green light if X >- 0 and a red light if X<0).
• You can now reset all controls to their default values either through a button command or via a context menu when designing the Dashboard.

Additional Minor Enhancements

A large number of minor modifications were also implemented.  The most notable of these are:

• The expanded Open and Save File dialogs are supported when using Windows Vista.
• Print Preview (which was previously disabled) is now supported again.
• Improved Hyperlink object functionality.
• Financial elements now support negative discrete changes.  For example, a negative Deposit is now accepted and treated as a Withdrawal).
• You can now browse into SubModels within the Function of or Affects browser.

Release Notes GoldSim 9.60

New in GoldSim 9.60 SP5

GoldSim 9.60 SP5 (Service Pack 5) was released on February 24, 2010.  However, anyone with a Subscription that did not expire before January 30, 2008 will be able to run this version.

Effective in the Spring of 2010, licenses for GoldSim versions prior to 9.60 SP5 will no longer be valid.  GoldSim 9.60 is several years old, and has been superseded by other versions.  However, a number of organizations have legacy GoldSim 9.60 models, and GoldSim 9.60 SP5 was released in order to extend the duration for which GoldSim 9.60 licenses will be valid.  GoldSim 9.60 SP5 also uses the newest licensing software version (as of February 2010), which is fully compatible with the current GoldSim release version as of February 2011 (GoldSim 10.11).

Other than for the licensing changes, and a number of bug fixes (also provided in 9.60 SP4 HotFix 1), GoldSim 9.60 SP5 is functionally identical to GoldSim 9.60 SP4. 

Installing GoldSim 9.60 SP5

Prior to installing GoldSim 9.60 SP5, you should uninstall any prior version of GoldSim 9.60 that is on your computer.

When you download from the GoldSim Web site, an installation file called GS9605.exe will be copied to a folder that you select on your computer.  You should have at least 200 MB of disk space available before downloading.

Once you have downloaded GS9605.exe, simply double-click on it to install GoldSim on your machine.  Once GoldSim is installed, you can delete the installation file.

Enhancements and Corrections in 9.60 SP4

GoldSim 9.60 SP4 (Service Pack 4) was released on January 30, 2008.  GoldSim 9.60 SP4 includes some minor feature enhancements and several bug corrections to GoldSim 9.60 SP3.  All reported bugs were corrected, with the exception of some minor user-interface issues.  Specific items that were modified include:

• The CT Module’s Network Pathway element was modified to support up to 999 watch groups for monitoring internal flux rates.
• The Function-of and Affects browsers that let users follow the chain of logic through a model have been modified to allow tracing logic into and through SubModel elements.
• Corrected a problem with the Time Series element that could cause it to compute incorrect ‘Average value over timestep’ when extremely short timesteps occurred.
• Corrected a problem when using recording Time Series elements inside looping Containers.
• Corrected a problem with the Event Generator element, for the option ‘time to next event occurrence’, where the event time would not be rescheduled unless the input time changed.
• Corrected a problem with the Dashboard’s ‘digital output display’, which could cause a crash if its value was updated at an extremely high rate.
• Corrected a problem in SP3 where an invalid input to an Allocator element would cause a crash while editing the model.
• Corrected a problem where a Submodel could erroneously accept a link that caused an invalid (recursive) model sequence.
• Corrected some problems associated with the Submodel element’s interface definitions.
• Corrected a problem where a Submodel user interface could be changed without the versioning system recording the change.
• Corrected a problem in computing sensitivity analysis coefficients for very large matrices (due to roundoff).  Also corrected a problem where sensitivity analysis results were not updated after changing the input selections.
• Corrected a problem where a bad hyperlink could be created that would crash GoldSim when clicked on.
• Corrected a problem where a displayed result chart would be invalid following maximizing or printing.
• Corrected a problem associated with discarding results following an aborted simulation.
• Modified the Start_Time run property to be ‘static’ so that it can be used for inputs to the initial values of model elements.
• Corrected a problem in reversing changes when a user cancelled out of editing a previously-invalid input expression.
• Corrected user-interface problems that could cause crashes while running distributed processing.

Enhancements and Corrections in 9.60 SP3

GoldSim 9.60 SP3 (Service Pack 3) was released on November 16, 2007.  GoldSim 9.60 SP3 includes some minor feature enhancements and several bug corrections to GoldSim 9.60 SP2.  All reported bugs were corrected, with the exception of some minor user-interface issues.  Specific items that were modified include:

• A new run property, Start_Time, was added.  This represents the date/time of the start of the simulation.  It can be used to help specify initial conditions for a model.
• Modified the Time Series element’s behavior when it is set to record.  If it is in an active container at the start of the realization, it records and simultaneously outputs the signal that it is recording.  However, if its container is inactive at the start of the realization, the element outputs the last history that it recorded.
• Corrected a bug in the Allocator element, which affected how identical-priority outputs were allocated their shares.
• Corrected a bug in the Event Generator element that affected results for date-time models that had time-varying event rates.
• Corrected a bug in the Material Delay element that affected vector items with different delay times for each item.
• Corrected a bug in the CT module, where incorrect mass amounts could be calculated for Source and Pipe elements when decay chains had feedback loops.
• Corrected errors in the RL module that could cause crashes when displaying element performance results.

Enhancements and Corrections in 9.60 SP2

GoldSim 9.60 SP2 (Service Pack 2) was released on July 15, 2007.  GoldSim 9.60 SP2 includes some minor feature enhancements and a number of bug corrections to GoldSim 9.60 SP1.  All reported bugs were corrected, with one exception (dragging text from one GoldSim input field and dropping it into another input field can cause a crash).  Specific items that were modified include:

• A number of changes were made to reduce the time required for routine tasks, such as parsing large model files, moving elements or containers in large files, displaying time history results.
• Corrected a bug in the Allocator element, that prevented output values from dropping to zero when the input amount was insufficient for them to receive a fraction.
• Corrected a bug that could result in erroneous results for array-type “if then else” calculations.  NB: this is a potentially serious that could have resulted in incorrect results for users doing vector or matrix calculations.  See http://www.goldsim.com/downloads/Documents/IfTestIssue.pdf for information on how to check your existing models to see if they were affected by this bug.
• Corrected a bug that affected the import of temperature data (in C or F) to time series or lookup-table elements.
• Corrected a bug that prevented importing vectors defined as rows in Excel files.
• Corrected a bug that prevented using the “ symbol to represent inches.

Enhancements and Corrections in 9.60 SP1

GoldSim 9.60 SP1 (Service Pack 1) was released on April 20, 2007.  GoldSim 9.60 SP1 includes some minor feature enhancements and a number of bug corrections to GoldSim 9.60.  Specific items that were modified include:

• Allow feedback loops in decay chains used by Pipe elements provided they are unused.
• Allow the Fund, CashFlow, and Investment elements to accept negative discrete change inputs.
• Player file users cannot change the simulation duration.
• Using the GetColumn() function on a vector item caused GoldSim to crash.
• Clicking the “Export now” button in a new Time History element could cause GoldSim to crash.
• The Splitter and Allocator elements permitted duplicate output names.
• GoldSim crashed if the array-labels for the columns of a matrix-type Time Series element were changed.
• Pipe and Network pathway elements could give inaccurate results when used for extremely long simulation times.
• The total mass reported for a Network Pathway could be incorrect.
• The CellNet Generator element always placed the generated elements in the model root container.
• Dashboard buttons that were defined as transparent appeared black when opened with the GoldSim Player.

Enhancements and Corrections in GoldSim 9.60

GoldSim 9.60 was released on March 9, 2007.  GoldSim 9.60 includes a number of major enhancements, as well as a significant number of general improvements and minor bug corrections to GoldSim 9.50 in order to improve performance and stability.

Note that GoldSim 9.60 no longer supports old-style Table elements. Users who wish to convert old-style Table elements into the new (reference-only) style should first open their models in GoldSim 9.50, which has an option for automatic conversion of old-style Table elements (just edit each Table element and press the “Convert…” button).  Converting old-style Table elements for use in GoldSim 9.60 is discussed in detail in a brief document that can be found in the Start Menu (under All Programs | GoldSim 9.60 | Release Info | Converting to 9.6).

The most significant changes included in GoldSim 9.60 are listed below:

• The Material Time Series and Information Time Series elements have been retired, and replaced by a single new Time Series element which is both simpler and more versatile than the old elements.  Existing models with Material or Information Time Series elements will be automatically converted.  Refer to the Help information or the User Manual for documentation of the new Time Series element.  Amongst other capabilities, the Time Series element is now capable of recording a time series that can be ‘played back’ later.  The automatic conversion of Time Series elements is discussed in more detail in a brief document that can be found in the Start Menu (under All Programs | GoldSim 9.60 | Release Info | Converting to 9.6).
• Options have been added to the Simulation Settings dialog to allow a user to use calendar-based (monthly, quarterly, or annual) as opposed to constant timesteps in their models.  To learn about this feature, open the Help system, select the Index tab, and enter "Timesteps", and then select "calendar-based".
• Results inside of SubModels can now be saved and viewed.  To learn about this feature, open the Help system, select the Index tab, and enter "Submodels", and then select "saving results inside".
• The user interface and functionality for External elements and External Pathways (in the CT Module) has been enhanced and improved.  Among other things, external functions can now input and output Time Series.
• As mentioned above, the old-style lookup Table elements have been retired.
• At the start of a new simulation GoldSim’s “Timestep_length” parameter used to be set equal to 0.  In GoldSim 9.60 it is set equal to the first defined timestep’s length.  This allows users to divide by Timestep_length with causing a divide-by-zero error.
• Array-label sets are now allowed to have a single item (previously at least two items were required).
• The unit “L” for liters can now be used with SI-type modifiers, e.g. mL, ML, GL etc.
• The Distributed Processing module has been enhanced for faster file transfer and greater stability.
• Numerous changes were made to correct minor bugs and to improve stability and performance when linking GoldSim to spreadsheets.
• Numerous changes were made to correct minor bugs and to improve stability and performance when using SubModels.
• The Watch Groups features within Network Pathways (in the CT Module) has been enhanced.
• An error in the element sequencer has been corrected that had the potential to put static elements inside subsystems in an incorrect update order. The problem has existed since GoldSim 9.00.

Release Notes GoldSim 9.50

Enhancements and Corrections in GoldSim 9.50

GoldSim 9.50 was released on October 8, 2006.  GoldSim 9.50 includes a large number of major enhancements (including 10 new elements), as well as a significant number of general improvements and minor bug corrections to GoldSim 9.21 in order to improve performance and stability.

In addition to these Release Notes, a more detailed document that summarizes the major new features in GoldSim 9.50 is provided in the Start Menu (under All Programs | GoldSim 9.50 | Release Info | Summary of New Features).  It is strongly recommended that all existing GoldSim users read this document!

Major New Features

The most significant changes included in GoldSim 9.50 are listed below:

• A new Splitter element has been added. These elements split an incoming signal according to some specified fractions or amounts.  Typically, the signal will be a flow of material (e.g., water), but it could also be a resource, or a discrete transaction.
• A new Allocator element has been added. Allocator elements allocate an incoming signal according to a specified set of demands and priorities.  Typically, the signal will be a flow of material (e.g., water), but it could also be a resource, or a discrete transaction.
• A new History Generator element has been added.  History Generators allow users to easily generate stochastic time histories, and should be  useful for simulating financial and economic variables (e.g., security prices, interest rates), as well as stochastic variables in other arenas (e.g., demands for resources such as water).
• A new Interrupt element has been added. The Interrupt element is triggered by an event, and responds by interrupting the simulation. The triggering event can be a discrete event signal or another type of event (e.g., a condition, such as X becoming greater than Y).
• A new element has been added (called a SubModel) that allows you to embed one model within another model.  This powerful feature facilitates a number of advanced modeling applications, including two-dimensional Monte Carlo analysis and probabilistic optimization.
• An entire new module has been added to GoldSim: the Financial Module.  The Financial Module provides five types of financial elements to support simulation of financial systems or financial aspects of engineering systems. It allows you to probabilistically simulate components such as accounts and funds, investments, options, projects or undertakings with specified cash flows, and insurance policies.
• In previous versions of GoldSim, local variables were accessed using the prefix "local".  For example, within a Looping Container, the loop counter was accessed as "local.LoopCount".  The "local" prefix has now been replaced by the tilde (~).  For example, within a Looping Container, the loop counter is now accessed as "~LoopCount".
• In some cases, it is useful to retrieve a particular item from a 1-D array (a vector) or a particularly row or column from a 2-D array (a matrix).  GoldSim 9.5 provides new functions to facilitate this.
• A new tab has been added to the Simulation Settings dialog to allow you to define global properties (constants) that can be referenced throughout the model.
• To better support the development of financial models, GoldSim 9.5 now provides an easier way to access and modify currency units.  In particular, GoldSim now provides a new menu option (under Model in then main menu) for editing and defining Currencies….
• All input edit controls in Dashboards (input edit fields, checkboxes and sliders) now contain an extra field for specifying whether or not the control can be changed by the user during a simulation.
• The Calculator section of a Stochastic (and Distribution result) now displays a new statistic, the Conditional Tail Expectation for the specified Cumulative Probability/Value pair.
• Material Time Series elements now display a fatal error if they encounter a negative values.  Previous versions allowed negative value.
• An error in the distributed processing logic has been corrected that has existed since GoldSim 9.10 (September 2005).  In simulations where not all of the realization histories were saved the calculated time-history statistics are partially incorrect: the standard deviation and quantile values are invalid.  The minimum, maximum, and mean values are correct.
• Numerous changes were made to improve stability and performance when linking GoldSim to spreadsheets.

Release Notes GoldSim 9.2

Enhancements and Corrections in GoldSim 9.21

GoldSim 9.21 was released on April 28, 2006.  GoldSim 9.21 includes several minor enhancements, particularly to time history result elements and plots, as well as a significant number of general improvements and minor bug corrections to GoldSim 9.20 in order to improve performance and stability.

The most significant changes and corrections included in GoldSim 9.21 are listed below:

• In previous versions, when plotting probability histories of multiple outputs with multiple realizations, GoldSim always plotted (or displayed in tables) the mean value for each output.  In 9.21, the user can now select what statistic to plot and display (e.g., median, mean, or a specified percentile).
• A new export format has been added to Time History Result elements. The new export option creates a simple ASCII text file in the form of a table.  It has a format similar to the Table View of the output.  Each row in the table is exported as a single row in the text file, and values are separated by tabs.
• A new option has been added to Time History Result elements to enable deactivation of the element.  When a Result element is deactivated, it no longer forces the outputs that it references to be automatically saved.
• In all previous versions of GoldSim, Reservoir elements could not accept Discrete Changes with a Replace instruction.  In 9.21, the Discrete Addition field in a Reservoir can now accept Discrete Changes with Replace instructions.
• A number of improvements and corrections were made to support defining and importing/exporting species in the Contaminant Transport Module.
• Changes have been made to improve the performance of models when deleting large containers.
• In GoldSim 9.20, the Stochastic element distribution dialog was not accessible in Result Mode.  This problem has been corrected.
• Source Containers did not previously support aliases for exposed outputs.  This problem has been corrected.

Enhancements and Corrections in GoldSim 9.20

GoldSim 9.20 was released on January 18, 2006.  GoldSim 9.20 provides a number of enhancements to the Contaminant Transport and Radionuclide Transport (CT and RT) modules, as well as some general improvements and corrections to GoldSim 9.10 SP2.  It also incorporates significant enhancements to the performance and stability of linkages to Excel spreadsheets.

One significant bug was corrected in GoldSim 9.20.  This bug, which has existed since GoldSim 9.00, affected the CT and RT modules’ Pipe and Network pathway elements.  An error would occur with these elements if either a material property or an outflow rate changed during a simulation.  The result of the error was that any contaminant masses introduced to the pathway during the timestep preceding the change, and which had not yet been discharged from the pathway, would be lost from the system.

GoldSim 9.20 provides the following new features for the CT and RT modules:

• The Source element has been significantly modified, and now serves as a container element.  All Cell elements associated with a Source element must now be placed within the Source.  Users with existing pre-9.20 models that use Source element should refer to the conversion notes below for information about how to convert their models.
• The Species element’s information can be exported to and imported from a spreadsheet.  This allows for the transfer of a species list, along with decay properties, between GoldSim models.  Also, new options allow for specification of decay rates as either rates or half lives, and for sorting of the species list by either name or atomic weight.
• The Cell-net generator element has been enhanced with better support for axisymmetric models, direct links to media types, and an option for anisotropic diffusion properties.
• The Network Pathway element, typically used to represent transport through fractured rock masses, has been enhanced to support “Watch Groups” which track the mass flux through selected ‘windows’ within the system.  This allows the user to monitor the progress of transport through a complex network.

In addition, a number of minor corrections and upgrades were made to GoldSim.

Source Element Conversion

The GoldSim CT Module’s Source element was modified in GoldSim 9.20 so as to make the logic of “Associated Cells” much clearer.  As discussed in the GoldSim Contaminant Transport Module User’s Guide, Associated Cells and their interconnecting flux links are automatically scaled in proportion to the number of failed Source containers.  Prior to GoldSim 9.20, any Cell in the same Container as a Source was automatically designated an Associated Cell (unless the user manually edited the Cell and deactivated the association).

As of GoldSim 9.20, the Source element acts as a container.  This means that other elements can be placed inside a Source element.  There are two purposes for this change:

• Associated Cell elements are now uniquely identified by being placed within their associated Source.
• Any other elements that represent logic associated with a specific Source can now be located within the Source, for greater model clarity.

When a pre- 9.20 model that used Source elements is first loaded, a dialog will appear that summarizes the number of Source elements and their Associated Cells.  Before the model can be run using GoldSim 9.20 (or higher), each associated Cell must be moved into its associated Source.  This can typically be done by dragging and dropping it onto the Source.  If the Cell is in a different container than the Source, right-click on it and select the Move option.  (Note: if the elements that are moved are inside a localized Container, and they have outputs that are exposed on the localized Container, these outputs will have to be re-exposed after the elements are moved).

Optionally, other elements can also be moved inside a Source element.  However, Source elements cannot contain other Source elements.

Release Notes GoldSim 9.1

Enhancements and Corrections in 9.10 SP2

Service Pack 2 (SP2): GoldSim 9.10 SP2 was released on November 11, 2005, to correct the following problems:

• Importing of Table element data from spreadsheets may fail if the model accesses multiple spreadsheets.
• An error in the calculation sequence can occur in rare cases where feedback loops are involved, and can result in incorrect solutions of Cell networks for time = 0.
• Several other user-interface and installation problems.

Enhancements and Corrections in 9.10 SP1

Service Pack 1 (SP1): GoldSim 9.10 SP1 was released on November 4, 2005, to correct the following problems:

• A problem with displaying probability time-history results, when not all time histories were saved.
• An error in the sequencing logic for Reservoir element “Overflow rate” and “Actual withdrawal rate” outputs.  This error allowed these outputs to be treated as ‘state variables’, which was not correct.
• Formatting problems with dashboard input fields when using % units.
• Several other user-interface and installation problems.

Enhancements and Corrections in GoldSim 9.10:

GoldSim 9.10 was released on September 25, 2005.  GoldSim 9.10 provides a new GoldSim module, the Reliability (RL) module, as well as some enhancements and correction to GoldSim 9.00 SP1.

The Reliability Module provides a number of powerful features for simulating the performance of complex engineered systems.  See the Reliability Module product page on the GoldSim web site for additional details.  All licensed GoldSim users have access to the RL module, however unless an RL-specific license is acquired no more than ten (10) of the new RL elements can be used in a model.

GoldSim 9.10 also provides the following new features:

• The Reservoir element has been enhanced to anticipate the times when its value would hit its upper or lower bound, and it automatically generates an event in the system time queue.  This means that longer time steps can be used without concern for the accuracy of Reservoir element results due to overshooting a limit.
• Automatic conversion of version-8 models has been enhanced, so that previous-value links for events and discrete changes are now automatically converted to use Previous Value elements.
• The Status element now reports an error if it receives both a True and a False trigger at the same time.

In addition, a number of minor corrections and upgrades were made.  Items of note include the following:

• Some issues with dashboard output values not being updated, or incorrectly being editable, were corrected.
• A number of problems with Spreadsheet elements were corrected.
• A problem where a normal distribution Stochastic with a zero standard deviation would cause a crash was fixed.
• A problem was corrected with result interpretation, for condition-type results, that occurred when the Monte Carlo model used importance sampling.
• Problems in running Sensitivity analyses were corrected, including a problem when controlling the probability levels of Stochastic elements.
• Problems when using the changed(..) or Occurs(..) operators in the input to a Data element or an And element were corrected.
• A problem with generating statistical history results for values larger than 1e20 was corrected.

Release Notes GoldSim 9.0

Enhancements and Corrections in GoldSim 9 SP1

 Service Pack 1 (SP1): GoldSim 9.00 SP1 was released on June 21, 2005.  Some of the problems fixed in GoldSim 9.00 SP1 are:

• Corrects problems with the Previous Value element’s initial value.
• Allows the use of Selector elements to define initial values for other elements.
• Fixes a minor chart axis labeling problem and an error in date-time based probability history charts.
• Corrects a problem with units for the Pareto distribution of the Stochastic element.
• Fixes a problem with the Reservoir element, which could produce incorrect results after it receives a discrete change during an unscheduled timestep (due to an event of some kind).
• Fixes a problem with the Timed Event Generator element, which caused GoldSim to freeze if the element is used in date-time simulations.
• Miscellaneous minor user-interface enhancements.

Enhancements and Corrections in GoldSim 9.00:

GoldSim 9.00 was released on May 24, 2005.  GoldSim 9 provides a number of significant new features, including the following:

• Enhanced graphics allow customization of the colors and shapes of influence arrows (including support for curved arrows), draw influences from center-to-center of elements (instead of from port to port), and use auto-layering of graphics.  These modifications provide a much improved look and feel to the user interface.
• Improved influence filtering, such that influences can now be filtered differently in each Container and filtering can be specified based on the type of data that the influence represents (e.g., continuous values or discrete signals).
• Improved timestepping algorithms to support both continuous and discrete simulations, including the ability to dynamically adjust the timestep during a simulation based on the current value of variables in the model.
• Enhanced Container functionality, including the ability to create:
• Looping Systems defined by do-while or repeat-until conditions; and
• Internal Clock Systems which allow specific Containers to have a different (smaller) timsteps than the rest of the model.
• Simplified approach to creating conditional systems with activation and deactivation rules.
• Enhanced and tighter integration with Microsoft Excel ^® spreadsheets, including:
• User-interface for selecting reference cells directly in Excel from GoldSim;
• Ability to use dynamically calculate cell offsets (row, column, sheet) based on a GoldSim expression;
• Ability to manually or dynamically import Time Series and Table element data from a spreadsheet; and
• Ability to manually or dynamically export simulation results to spreadsheets.
• Enhanced support for discrete-event models, including an improved triggering dialog.
• Automated sensitivity analysis capabilities, including:
• A new Multi-Variate Result display that provides statistical measures of sensitivity; and
• A separate run option that carries out calculations that provide additional graphical sensitivity analyses (e.g., tornado charts).
• Automated global Optimization capabilities.  The new optimization features allow you to specify an objective function (a specific result that you would like to minimize or maximize), a constraint (a condition that must be met), and one or more optimization variables (variables in your model that you conceptually have some control over). GoldSim then runs the model multiple times, systematically selecting combinations of values for each of the optimization variables.  By doing so, GoldSim can determine the values of the optimization variables that optimize (minimize or maximize) the objective function while meeting the specified constraint. 
• New powerful elements:
• An enhanced Lookup Table element, which combines the former three Lookup Table elements into one element and adds new functionality such as the ability to link directly to spreadsheets.
• The Random Choice element, which is similar to a Decision element, and is particularly  useful for representing event trees (processes consisting of specified random event sequences).
• The Previous-Value element, which replaces the ~ operator and provides access to the previous value of any model output.  This element is particularly useful for simualating recursive systems, and facilitates looping calculations within the new Looping Container.
• Improvements to the GoldSim licensing system designed to make it easier to manage your license.  For example, you can now run multiple GoldSim versions on a single machine using a single license. 
• A problem related to moving cloned Containers has been corrected.  In previous versions, if you moved a cloned Container, all of the cloning information was lost (the Container and its contents were no longer cloned).  This has been fixed.
• Several very powerful additions to the Contaminant transport module:
• A new CellNet Generator element to automate the creation of large networks of Cells.
• A new mass flux link has been added (precipitate removal mass flux links) that can be used to transport precipitated mass directly from one pathway to another.
• A new mass flux link has been added (treatment mass flux links) that can be used to provide a mechanism for treating or removing a fraction of the amount of mass entering a Cell.

In addition to these major changes, GoldSim 9 also includes a large number of smaller improvements and modifications, as well as a number of bug fixes.  As pointed out above, in addition to these Release Notes, a more detailed document that summarizes the modifications in GoldSim 9,  and discusses any issues related to converting model files from GoldSim 8 is provided in the Start Menu (under All Programs | GoldSim 9.0 | Release Info | Converting v8 Models).  It is strongly recommended that all existing GoldSim users read this document!

Release Notes GoldSim 8.0

Enhancements and Corrections in GoldSim 8.02 SP4

Service Pack 4 (SP4): GoldSim 8.02 SP4 was released on March 25, 2005.  Some of the problems fixed in GoldSim 8.02 SP4 are:

Click here for a complete list of changes.

Service Pack 2 (SP2): GoldSim 8.02 SP2 was released on September 13, 2004.  GoldSim 8.02 SP2 corrects a minor calculation-sequencing problem found in SP1, and modifies the standard run-log file format to reduce the number of unimportant messages that are recorded.

Service Pack 1 (SP1): GoldSim 8.02 SP1 was released on August 20, 2004.  GoldSim 8.02 SP1 corrects a significant CT-module bug plus some minor problems found in GoldSim 8.02, and adds two new features.  The significant changes are:

• For decay-chain solutions the CT-Module ‘direct-transfer-rate’ option could ‘shuffle’ its outputs.  This was corrected.
• The Event-Delay element can now have the delay times randomly sampled from a Stochastic element’s distribution.
• The Timed Event Generator can now have the event times randomly sampled from a Stochastic element’s distribution.

Enhancements and Corrections in GoldSim 8.02:

GoldSim 8.02 was released on June 25, 2004.  GoldSim 8.02 combines all previous service packs and adds a small number of additional corrections and additions.

• Corrected a problem with reparsing elements.
• Changed expression updating and pre-run model checks.
• Fixed shortcut keys for subscript and superscript fonts in text boxes (Ctrl-=, Ctrl-+)
• Improved reparse performance for distributed processing simulations.

Enhancements and Corrections in GoldSim 8.01

Service Pack 6 (SP6): Service Pack 6 for GoldSim 8.01 was released on May 28, 2004.  SP6 includes three fixes:

• Corrected a problem where an element’s name could be changed but not all elements referencing it would have the references corrected.  This problem existed in all earlier version of GoldSim, but seldom occurred and usually generated an error message that the user could easily correct.
• Modified the contaminant transport algorithm to allow carrying out of transport and decay calculations for masses as small as 1e-24 kg (high precision option).          
• Modified the contaminant transport algorithm to allow shorter time sub-steps, and to limit the generation of warning messages for zero-solubility chemical elements.           

Service Pack 5 (SP5): Service Pack 5 for GoldSim 8.01 was released on April 22, 2004.  SP5 includes a number of minor fixes, plus the following:

• Corrected an SP4 problem where a CT solution could hang and not complete.
• Corrected an SP3-4 CT problem where the amount of contaminants exposed during a timestep could be too large.
• Increased the efficiency of model re-parsing.
• Allow triangular probability distributions to have min = mode = max..
• Corrected a problem where Reservoir elements with multiple discrete changes could cause a GoldSim crash.         

Service Pack 4 (SP4): Service Pack 4 for GoldSim 8.01 was released on March 19, 2004.  SP4 includes a number of minor fixes, plus the following:

• The method used to create the Latin hypercube strata in GoldSim was modified so as to have completely separate, independent sets of strata.  (All previous version of GoldSim used the same suite of strata for different Stochastic elements, simply shifting the array of strata by one for each element).
• License error checking and reporting of license errors has been enhanced.
• Last run log is available for display in edit mode.
• Error checking in the cell-net solver of the CT/RT module has been improved.
• Chart keyword %#cr% has been added to allow automatic display of current realization number  

Service Pack 3 (SP3): Service Pack 3 for GoldSim 8.01 was released on February 23, 2004.  Note that it is NOT file-compatible with the previous two 8.01 Service Packs.  Users wishing to read GoldSim files saved using SP3 will need to install SP3 or a later version of GoldSim.  SP3 includes a number of minor fixes, plus the following

• The Integrator element has been given an option to use a ‘backwards-looking’ integration algorithm, which applies the current rate of change to the previous time step.  (By default, the current rate of change is applied to the next time step).  This option is intended to allow CT/RT-module users to integrate mass fluxes in a way that is consistent with the CT/RT modules.  Enable the feature using the Model/Options dialog, and then each Integrator element will provide a new tab to allow you to enable the feature for that element.
• A bug was fixed that would affect model results if a) importance-sampling was enabled for some Stochastic elements, and b) the Distributed Processing option was selected.
• The CT/RT module was enhanced for better solution of problems involving both huge and small masses, and to give more precise warning messages if negative masses were created (and ignored) during a solution.
• Some problem areas involving extremely large models and results, run using the Distributed Processing module, were resolved.
• A new Convolution element, which lets you project future consequences that can be mathematically described as convolution integrals .  For example, if you are selling new cars at a rate of 1000 per month, what are your future liabilities for warranty repairs?  Convolution can be used to solve problems like this.
• You can now define data arrays (vectors and matrices) within an input field using array constructor functions.
• Stochastic elements can now be defined as vectors.
• Date/Time models are no longer limited in their duration (previously, they could not extend beyond 2035).
• Improved functionality for globally changing symbols for elements.  For example, you could instruct GoldSim to change the symbols for all Integrator elements in the model to a specified image.
• Improved Hyperlink functionality.  The Hyperlink object is now more powerful and easier to use.
• Improved array functions.  The If statement now supports term-by-term calculation (i.e., the condition can be an array).  You can also raise an array to a power, and the calculation will be carried out term-by-term.
• Improved triggering functionality.  The Trigger dialog for specifying triggering events now support two additional types: OnFalse and IfTrue.  In addition, you can specify multiple events and instruct GoldSim not to pull the trigger until all events have occurred.
• Improved sequencing logic.  The sequencing logic in GoldSim has been totally redesigned.  This particularly improves the ability of GoldSim to represent recursive discrete event systems.
• A new textbox object has been added.  This allows you to add scrollable textboxes (with multiple fonts) to the graphics pane.
• The equality operator can now be entered as either == or = (previously, only == was accepted).
• When you open a model file that contains large amounts of simulation results, the results can now be loaded in the background while the model can be browsed and individual results viewed in the foreground.
• Lists of slave names or their IP addresses used for complex distributed network runs can be imported from or exported to files.
• GoldSim internally stores images (e.g. background pictures) in a highly compressed format that preserves the quality, color depth and resolution of the original. GoldSim also supports a number of new graphic file formats.
• A new slave manager service (only supported on Windows NT and above) has been added that can remotely launch slaves for distributed network simulations.
• The distributed networking module (DP) has been largely rewritten for faster and more reliable communication, data exchange and simulation execution.
• Model files can now be larger than 2GB (on NTFS file systems only) and support virtually unlimited amounts of history results.
• Generalized units ‘date’ and ‘datetime’ have been added to provide better support for time-based display units.
• Viewing probabilistic results of conditions and discrete distributions has been improved.
• Two new outputs (the number of realizations and the total duration) have been added to the MasterClock.
• Discrete Changes and Discrete Change Delays can now handle matrices (previously, they could only handle scalars and vectors).
• When exporting charts, more graphics formats are now available.
• Units for several foreign currencies (euro, yen, pound sterling) are now supported (i.e., you can add new units for these).
• A new % unit has been added so you can enter data as percentages.
• The Information and Material Delay elements now allow you to specify the Delay Time and Dispersion as arrays (if the input signal is an array), and then each item is delayed separately.
• The CT (Contaminant Transport) and RT (Radionuclide Tranport) modules also have some significant changes:
• The old ‘Chain-by-chain’ solution algorithm for cell-nets is no longer supported (it has been replaced by the faster “family-by-family” algorithm.
• A change has been made in how partition factors are defined for fluids that have defined solubilities:

Significant CT/RT Changes

• For any fluid for which solubilities have been defined, GoldSim will internally compute a partition coefficient for the species in that fluid (with respect to the reference fluid) that is equal to the ratio of the solubility of the species in the fluid to the solubility of the species in the reference fluid.
• If the reference fluid has an unlimited solubility for a species, any other fluids with specified solubilities must also have an unlimited solubility for that species (and  GoldSim will assume a partition coefficent  equal to unity).
• If you wish a fluid to have different solubility limits from the reference fluid, but to have a partition coefficient relative to the reference fluid of 1.0,  you can do so by creating a  clone of the reference fluid.
• A new ‘direct transfer’ option for mass flux has been added to the existing advective and diffusive capabilities.  This new option provides a very general first-order transfer process for cases that aren’t advective or diffusive.
• Contaminant species can have up to four daughter products.
• The stoichiometry of a species can now be a link (rather than a constant).
• Cells now compute the Dissolved Concentration in fluids (if a suspended solid is present) and the Precipitated Mass (i.e., the total amount of mass in the cell which has precipitated out of solution).
• Cell-nets can span multiple Containers.
• Associated Cells (for Sources) can now reside in Containers other than the Source Container.
• Fixed a problem with correlation factor of -1 between stochastic elements.
• Fixed a problem with suspended solids in Pipe elements.
• Fixed numerous minor editing and cosmetic problems.

Enhancements and Corrections in GoldSim 7.51.1

• Fixes a problem with hyperlink components, which did not always function correctly when embedded in dashboards.
• Fixes problems when cloning Material Time Series, Information Time Series, Sum, Extrema, Fluid and Source elements.
• Fixes a problem with constant date/time strings (e.g. “01/01/2003”) in input expressions. GoldSim mistakenly requested a unit string to be added to the date.
• Fixes a problem with memory buildup while running complex models.
• Fixes a problem with the result file import function, which is used to import single realization result files that were output during a distributed processing simulation.
• Fixes several problems with large system fonts.
• Fixes a CT/RT-module problem for better convergence of low-solubility, low-mobility species.

Enhancements and Corrections in GoldSim 7.51

Major Changes in 7.51:

• A new distribution type, the Student’s t-distribution, has been added to the Stochastic element.
• Almost all math and logical functions in GoldSim now support arrays. For example, for matrices A and B the expression A * B will create a new matrix with each term being the product of the corresponding terms in A and B.  Also, sin(A) would now produce a matrix containing the sine of each term in A.  The details of these changes are described in a separate document GS_75_NewMathFuncs.pdf.
• The way that GoldSim manages result memory has been redesigned, so that more results can be generated using less RAM memory. When GoldSim is running, the time history results are now stored in a temporary result file. The result data are automatically loaded and cached in memory only for as long as needed for result display.
• Time history results are now compressed when saved to the model file, allowing for larger result sets to be created.
• Application memory tuning (a.k.a. 4-gigabyte tuning or 4GT) is applied by default. This feature allows GoldSim to use 50 percent more virtual memory (up to 3 GB) on Windows 2000 Advanced Server or Windows 2000 Datacenter Server.
• External elements can optionally be flagged to run in separate processes. This frees the GoldSim process space during the simulation and allows larger external processes and more results to be stored. Each such external process can use up to 2 GB (3 GB with 4GT) of virtual memory.
• A basic printing capability for result tables has been added.  This can be used to print out time histories, result statistics, etc.
• New math functions have been added for calculating normal, Student-t and gamma distributions.
• Cumulative and discrete data tables from Stochastic elements can now be copied to the clipboard.
• GoldSim no longer supports Microsoft Windows 95.  While it will still run on Windows 95 systems, compatibility will not be guaranteed for future releases.

Significant CT/RT Changes:

• An optional enhanced cell-net solver algorithm has been added, which will produce much faster, more stable solutions with large numbers of Cell elements.  This option is the default for new models, and can be modified from the Model/Options/Contaminant Transport menu.  The new option is called the ‘family-by-family’ algorithm, and the original option is called the ‘chain-by-chain’ algorithm.
• A single user-definable precision setting, with a value of High, Medium, or Low has been added to the Options dialog.  This replaces the deHoog ‘nterms’ and also controls the accuracy of Cell-net solutions.
• An option to disable logging of CT/RT-specific warnings during a model simulation was added.
• For multiple isotopes, GoldSim will now generate a warning message if the specified solubility values are not proportional to the atomic weights of the isotopes.
• The Species element has a new output vector, called Mol_Weight, which provides the atomic (or molecular) weights of the species.  For models involving isotopes, users are encouraged to define solubilities using a simple formula:
  Define a data-vector (e.g. “SOLS”) containing the molar solubilities (mol/m³) for each species.  In the input-field for Water solubilities, simply enter the name of the solubility element multiplied by the atomic weights, e.g. “SOLS * Species.Mol_Weight”). This approach will give consistent values and avoid the warning messages that GoldSim will generate if inconsistent values are entered for different isotopes.

Significant Solved Problems/Bugs in 7.51

• Fixed a problem with the trunc() function when used with very small or very large numbers, e.g. > 2e9.
• Fixed a problem with Stochastic element’s gamma distribution, if a large mean value was used.
• A dashboard component that was linked to an input of a Data Definition element that also had clones, only updated the linked element but not its clones.
• Fixed a problem when pasting data into a grid, e.g. a vector or matrix edit dialog.
• Generating large result tables with more than 10,000 cells is now significantly faster.
• Fixed a problem with versioning, which mistakenly recorded global changes to result-saving flags.
• A problem with using the date-time option for simulations was fixed.  This bug could cause incorrect results for discrete change calculations.
• A problem with displaying confidence limits for some time-history results was fixed.
• A problem which could cause a fatal error in the material time-history element was fixed,.
• Pipe pathways were not correctly handling time-dependent changes to species decay rates.
• A roundoff problem that could cause a timed event to be emitted one timestep too late was fixed.
• Delay elements were given an improved algorithm for more accurate results.

Release Notes GoldSim 7.4

Enhancements and Corrections in GoldSim 7.40

This version is a minor release with only a few modifications from GoldSim 7.30. 

Note, however, that GoldSim 7.30 was a major new release with a large number of new features.  If you are upgrading from a version previous to 7.30, you should read the 7.30 Upgrade Document.  This document discusses some of the key changes in GoldSim 7.30, identifies those cases in which your results may be different from those generated by previous versions, and identifies those cases where old models may be invalid in the new version.

Major Changes in 7.40

This version contains the following notable new features:

• A capacity input was added to the Event Delay element.  The number of signals in the Delay cannot exceed the capacity.  Signals received while the Delay is at its capacity are stored in a queue until there is room in the Delay.  This facilitates the simulation of actual queues, such as that at a bank teller.
• You can now “lock onto” a DLL in an External element, a spreadsheet file in a Spreadsheet element, or any file referenced by a File element.  When you lock onto a file, a CRC signature is generated. The CRC signature is an alphanumeric code that can be used to uniquely identify whether the file contents have changed.  When you run a model that has locked onto a file, GoldSim compares the CRC signature of the file with the original signature that was stored.  If these are not identical (indicating that the file has been changed), GoldSim displays an error message and will not run the model.
• Vectors and matrices can now be downloaded into Data elements from Yucca Mountain databases and Simple databases.  Previously, they could only be downloaded from generic databases.
• A New Model Wizard was added to automatically set the major simulation settings when a new model is created.  (You can choose to disable the wizard through the Options dialog).

Minor Changes in 7.40

GoldSim 7.40 also includes a number of minor changes, the most significant of which are as follows:

• The license agreement is now viewed when you register (or upgrade) GoldSim, which for most users eliminates the need for printed license agreements.
• When you start GoldSim, a Start dialog automatically appears from which you can choose to open a new file, open an existing file, or open a recent file.
• Stochastic elements can now be cloned (previously, this was not permitted).
• Three new outputs were added to the MasterClock: DayofWeek, DayofYear and WeekofYear.
• When you download from a database to an element, the database download status information is now shown in the element’s tool-tip.
• The Model Author has been added to the Simulation Settings.  This is written to the Run Log and can be referenced via a keyword (%author%) in chart styles.
• Changing a result saving flag no longer triggers an entry in the version log.
• Academic versions of GoldSim are now limited to 500 elements.
• The Contaminant Transport Module now has two types of licenses: CT and RT.  CT does not have Source elements, Network pathways, and does not allow reaction (daughter products).  All existing licenses will automatically convert to RT licenses.
• The Distributed Processing Module now has two types of licenses: DP and DP Plus.  DP allows up to 5 slaves, while DP Plus allows an unlimited number of slaves. All existing licenses will automatically convert to DP Plus licenses.

Solved Problems/Bugs

GoldSim 7.40 addresses several minor bugs, the most significant being the following:

• Several bugs associated with copying, pasting and moving Dashboard controls (and elements linked to controls) have been corrected.
• GoldSim now applies more careful tests when checking the validity of previous-value (feedback) links, and when sequencing the calculations of models that involve previous-value links or discrete changes.

Release Notes GoldSim 7.3

Enhancements and Corrections in GoldSim 7.30.1

GoldSim 7.30 is a major new release with a large number of new features.  GoldSim 7.30 was previously released as a beta version (7.30.0) to a limited number of users for testing.  GoldSim 7.30.1 is a point release that addresses problems uncovered during beta testing. 

In addition to adding new features, some of the terminology in GoldSim has changed, and there have been some modifications to the underlying philosophy on which the software is based.  Most importantly, due to improvements in some of the algorithms, some existing models will compute (slightly) different answers with the new version.  In some rare cases, old models will need to be modified slightly before they will run in the new version. 

The changes have been documented in detail in an updated version of the user’s manual.  Because the changes are so significant, all users should update their documentation.  The significant changes are outlined below, and where appropriate, references are made to pages in the manual.

In addition, to make the migration to GoldSim 7.30 easier, a 7.30 Upgrade Document has been produced.  It is highly recommended that existing users read this document before using GoldSim 7.30.  The document discusses some of the key changes, identifies those cases in which your results may be different from those generated by previous versions, and identifies those cases where old models may be invalid in the new version.

Changes in Terminology

A number of modifications to GoldSim terminology have been made:

• Ordinal Sets are now called Array Labels.
• Accumulators are now called Integrators.
• Consequences are now called Discrete Changes.
• Events are now called Timed Events.
• Delays are now called Event Delays.
• Transaction outputs are now called Discrete Signals; Event Transactions are called Discrete Event Signals; Consequence Transactions are called Discrete Change Signals
• Feedback links are now called Previous Value Links
• Some of the Table and Field names for the result export database format have been changed (to be consistent with the changes outlined above).

Major Changes

This version contains a large number of major new features:

• Several powerful new elements have been added to support  discrete event simulation:
  • Decision element
  • Milestone element
  • Status element
  • Triggered Event
  • Discrete Change (Consequence) Delay

  These are discussed in detail starting on page 9-17 of the User’s Guide.

• The Event Delay element has been updated and improved in several ways:
  • The signal can now be dispersed while in transit.
  • The Delay behaves like a conveyor belt, which impacts behavior if the delay time changes dynamically.
  • Events no longer output a Completion Status.

  Event Delays are discussed in detail on page 9-31.

• Two new elements for delaying continuous signals have been added: Information Delays (page 4-108) and Material Delays (page 4-116).
• Two new elements for entering and manipulating time series data have been added: Information Time Series (page 4-38) and Material Time Series (page 4-50).
• A new logical (Not) element has been added (page 4-106).
• The integration algorithm for Accumulators (now called Integrators) and Reservoirs has been changed.  As a result, in most cases, feedback links (now called previous value links) will no longer be required. This is discussed in detail on pages 4-65, 4-70, and 4-126.
• Conditional Containers have been completely reworked and greatly expanded (page 9-48).
• Element triggering has been completely reworked and greatly expanded (page 9-20).
• Expressions are now colorized in input fields to make them easier to read and edit.
• Version Tracking has been added.  This allows you to track the changes made to your model file over time (page 9-83).
• All users now have access to the GoldSim Dashboard Authoring tools (described in detail in the GoldSim Dashboard Authoring Module User’s Guide).  In order to create Player files with Dashboards, however, your license must have Dashboard Publishing option activated.

Minor Changes

GoldSim 7.30 also includes a significant number of minor changes, the most significant of which are as follows:

• An Occurs function has been added.  This function accepts a discrete event signal as an argument, and outputs a condition (page 9-33).
• The Changed function has been modified.  It accepts a continuous input argument and outputs a condition (page 4-4).
• The functionality of the insert link dialog has been improved to make it easier to find elements (page 3-21).
• You can now insert jpeg images (although they are still internally stored as bitmaps).
• The Insert element menu is now hierarchical.
• Tool-tip functionality in expressions has been improved (tool-tips now can appear while you are editing).
• A number of commonly encountered error messages have been improved (e.g., for dimensional inconsistencies).
• Output icons in browsers have changed.  Discrete signal (transaction) outputs in the browser are differentiated by an exclamation point.
• The Main browser has been removed.  There is only a single browser now.
• Search capabilities in the browser have been improved (page 3-43).
• You can zoom in and out in the graphics pane using mouse wheel.
• You can navigate Containers using hot-key combinations (page 3-29).
• The size of the graphics pane document has been expanded.
• The Time History Result element is now more robust and flexible.
• Discrete Signals (transaction outputs) are ignored if received by elements in inactive Containers (in previous versions, they were stored).  See page 9-49.
• The default number of substeps is 0 if the  Contaminant Transport Module is not being used (and 10 if it is being used).
• When you replace an element’s image, GoldSim allows you to choose if you want the new image to be scaled to fit the existing element size, or if you want the element size to adjust to the new image size.

Solved Problems/Bugs

GoldSim 7.30 addresses a large number of minor bugs, the most significant being the following:

• Probability densities for discrete distributions were being displayed incorrectly.
• Axis label fonts were not being saved for result elements.
• The number of phases was limited to 5.
• Under some situations (small cell volumes, high flow rates), we could generate large overshoots (and create mass) within the CT Module (this was correctly noted in the run log).  The algorithm has been improved to better handle these situations.
• Several problems associated with exporting results to databases have been corrected.

Release Notes GoldSim 7.2

Enhancements and Corrections in 7.21 SP2

This version is a point release with minor modifications from GoldSim 7.21.  Note that while 7.21 SP2 is a verified version of GoldSim, the Player is still considered a beta version and is not verified.

• Result distribution analyses for Monte Carlo simulations can now display confidence bounds on the mean value of the result.
• In previous versions a Source element would stop releasing mass when it got below 1e-9 of its inventory.  This has been corrected so that all mass is released.
• For Pipe elements, a stagnant zone was required to have a solid medium specified or it would be ignored.  This has been corrected, and no medium is required.
• Pipe elements would incorrectly output invalid numbers following an event.
• Hyperlink elements would not jump the user into Containers or Dashboards.
• Financial math functions required an integer number of periods (months, years).  This is no longer required.
• GoldSim would crash when running on Windows 9x machines and a Sum, And, or Or element was edited.
• GoldSim could crash when running on Windows NT machines when editing inputs in grids.
• A conditional Container could not be re-activated based on its prior completion event.
• A bug was fixed where, in unusual circumstances, one of the Stochastic elements in a model could fail to correctly generate its random values.  This would occur only if the number of Stochastic elements exceeds the number of realizations by exactly one, with LHS enabled.
• Numerous minor problems with Dashboards and the Player were corrected.
• The reservoir element could incorrectly report an error if its lower bound was increasing more rapidly than its value.

Enhancements and Corrections in GoldSim 7.21 (Beta version)

GoldSim 7.21 incorporates several significant new features and internal modifications.  As a result it is treated as a beta version, even though it has been verified.  Users requiring the highest degree of confidence are advised to wait until the first point release (likely to be 7.21.100) before installing it.

Major Changes

• The manuals have all been updated.
• Edit fields for input expressions automatically expand.  These fields allow the user to view and edit arbitrarily long input expressions.
• Support for Dashboards and Player files has been added.  Dashboards are special containers that contain user-defined controls (sliders, etc.) and information that are designed to allow an untrained user to run the new GoldSim Player program.  Note that a special license is required in order to create Dashboarded files. The Dashboard Authoring Module User’s Guide has been posted along with the other manuals on the website.
• The Simulation Settings dialog has been modified.  Most of the changes are cosmetic.  However, a feature has been added to allow you to run a deterministic simulation, and override the settings specified for each Stochastic element.  For more information, see Chapter 6 of the GoldSim User’s Guide.

Minor Changes

GoldSim 7.21 addresses a significant number of minor changes, including:

• A number of modifications were made to the Spreadsheet element.  First, the changes made to a spreadsheet during a simulation can now be saved.  Also, a spreadsheet element is no longer required to have any inputs (e.g., if it is a data source).  Spreadsheet elements can now reference spreadsheet cells beyond column 26 (Z).  Finally, multiple Spreadsheet elements can access the same Excel file.
• When you define a specified (deterministic) value for a Stochastic, the value is saved when you switch to a multiple realization run.
• A new command line argument was added to allow you to read in an old GoldSim file, save it, and then close GoldSim.  When used in a batch file, this provides a convenient way to convert all of your GoldSim files to the latest format.
• The maximum cell-net matrix size was increased from 330 to 1000.
• Relative paths to hyperlinks in Notes can now be specified (previously, the full path was necessary).
• Access to databases has been streamlined.
• The tool-tip for Expression elements now shows the formula used.
• The thickness of influences is no longer determined by the number of links.  All influences, regardless of the number of links, have the same width by default.  The influence property dialog, however, allows you to adjust the thickness for each influence.  Existing models (in which the thickness reflects the number of links) keep their old thickness settings.  You can, however, modify the thickness individually for each influence.
• GoldSim now remembers the last viewed Container and displays the contents of that Container when the file is reopened.
• Printer settings for Containers are now applied to all Containers, not just the current one.
• The Extrema element can now output the time at which the maximum (or minimum) value occurred.
• New math functions rowmin( ) and rowmax( ) record the row number of the largest or smallest entry in a vector.
• Tables defining probabilities and values can now be copied from spreadsheets and pasted into cumulative and discrete Stochastic element definitions.
• Result time history tables can now display up to 10,000 columns (realizations).
• Switches can now be inserted into a Selector (previously, new switches were always added at the bottom).  In addition, the Switch dialog in a Selector is now resizable.
• A new status bar field has been added which provides additional information about the file and Container being viewed.
• A new keyword, the element’s description (%ed%n) has been added for use in result displays.
• Contaminant transport elements can no longer be within a conditional Container which gets deactivated. That is, if they are in a conditional Container, that Container can never be deactivated.  If it is, a fatal error will be displayed.

Solved Problems/Bugs

GoldSim 7.21 addresses a number of bugs, including:

• If a Cell or Pipe pathway had its output flux rate go to zero, GoldSim would retain its last non-zero flux rate rather than setting the rate to zero.
• For complex decay chains where a single parent had two daughters, and both daughters’ decay-chains subsequently merged, Pipe elements could lose the mass generated by one branch of the merged chain.
• Several bugs related to use of the ‘importing from database’ and ‘exporting to database’ have been fixed.
• Text objects can now contain empty lines (e.g., between paragraphs).  In previous versions, empty lines were ignored (removed).  In addition, word-wrap is now defaulted to on when a text object is inserted.
• Several bugs related to the Note window have been fixed.
• When you replace the symbol for an element in the graphics pane, the size setting is now over-ridden so that the new image is not distorted.
• Several bugs related to use of the Distributed Processing Module have been fixed.

Release Notes GoldSim 7.1

Enhancements and Corrections in GoldSim 7.17 SP1 and SP2

These versions are point releases with minor modifications from GoldSim 7.17:

• A problem that could cause slow file-save times after a very large network run was fixed.
• A memory-management problem for network solutions with large numbers of realizations was addressed (GoldSim 7.17.100 only).  This fix worked on some but not all Windows NT systems, and was removed in GoldSim 7.17.200.

Enhancements and Corrections in GoldSim 7.17

GoldSim 7.17 is a point release with several minor modifications from GoldSim 7.15.  These include:

• A bug was fixed which in unusual circumstances caused Extrema elements to give incorrect values in multiple-realization simulations.
• An error was fixed, that caused simulations solved using the Network solver to give incorrect probability time histories if not all time histories were saved.
• Some unclear error and warning messages were improved.
• A capability was developed to allow unloading a user-provided DLL after calling it.

Enhancements and Corrections in GoldSim 7.15

GoldSim 7.15 is a point release with several minor modifications from GoldSim 7.12.  These include:

• The model archiving process was redesigned such that model load/save speeds are significantly improved.
• The shortcut key to switch back to Edit Mode (F4) now works while element property dialogs are open.
• Fixed minor problems with default values using old-style unit definitions (i.e., curly braces).
• Fixed a bug in unit conversion of user-defined stochastic distribution types when exporting results to a database.
• Fixed a bug with selected vector sub-items in time history charts.
• Fixed a problem with container conditionality.
• Fixed a problem where elements could be pasted into a model while in Result Mode.
• Minor cosmetic improvements.

Enhancements and Corrections in GoldSim 7.12

GoldSim 7.12 is a point release with only minor modifications from GoldSim 7.11.  These include:

• Fixed a bug where Pipe elements give unreliable results following the occurrence of any Event.
• Fixed a problem where Expression elements could generate an incorrect error message.
• Minor cosmetic improvements.

Enhancements and Corrections in GoldSim 7.11

GoldSim 7.11 is a point release with only minor modifications from GoldSim 7.10.  These include:

• Fixed a bug which in unusual circumstances could cause one Stochastic element in a model to produce incorrect results.
• Fixed a problem where Reservoir elements could generate an incorrect error message.
• Improved the display of dynamic results in charts.
• Minor cosmetic improvements.

Enhancements and Corrections in GoldSim 7.10

A large number of new features and modifications have been made to GoldSim 7.10.  The key changes are highlighted below.

Major Changes

• The manuals have all been updated.  Due to the large number of changes (and the fundamental nature of some of the changes), you are strongly encouraged to update your documentation with this version.
• GoldSim simulations are now controlled using the GoldSim Run Controller.  Using the Run Controller, you can start and abort a simulation, as well as pause (to explore outputs) and resume it, and step through the simulation one realization or one timestep at a time.  (The next version of GoldSim will allow you to add breakpoints to an element so that the model will pause when a particular condition is met.) The Run Controller is described on page 6-13 of the GoldSim User’s Guide, and you are strongly encourged to read this section before using GoldSim 7.10.
• GoldSim now makes a strong distinction between Edit Mode, Run Mode and Result Mode.  You can only edit a model while it is in Edit Mode.  While Run Mode and Result Mode allow for some limited editing capabilities, most dialogs are locked in these modes.  This prevents you from creating a model which is inconsistent with the saved results.  In order to return to Edit Mode, you must abort the run (if in Run Mode) and/or discard the results.  The three GoldSim modes are discussed in detail on page 6-14 of the GoldSim User’s Guide. To return from Result Mode to Edit Mode you can press F4 or click the new toolbar icon which has been provided.
• Result elements can now be left open during a simulation so that you can view the results dynamically as they are generated during a simulation (see page 7-83 of the GoldSim User’s Guide).  The ability to manually slow down a simulation (using the Run Controller) facilitates the viewing of such plots even for simulations which run very rapidly
• Several restrictions have been added regarding the use of feedback links to ensure their proper application.  In particular, feedback links can now only originate from the following outputs:
  • Accumulators
  • Reservoirs
  • Expressions with Specified Initial Values
  • Transaction outputs (i.e., events and consequences);
  • All Contaminant Transport Module elements.

  In addition, the Initial Values for Accumulators, Reservoirs and Expressions cannot themselves be functions of feedback links.  These limitations are discussed on page 9-17 in the GoldSim User’s Guide.  Note that due to these new limitations, some existing models may now contain invalid expressions that will need to be modified prior to running your model.

• A new database format for importing data into a GoldSim model has been added.  This format (referred to as a Simple GoldSim Database) is discussed on page 9-39 of the GoldSim User’s Guide.
• You can now specify a “deterministic value” for each Stochastic element in your model.  The deterministic value can be the mean, the median, a specified quantile, or a specified value.  When you run a “deterministic simulation” in GoldSim, the specified “deterministic value” is used for each Stochastic.  This is discussed in detail on page 4-26 of the GoldSim User’s Guide.
• The manner in which Initial Values for outputs within inactivated Containers are evaluated has been modified:
  • Before becoming active, all elements except constant Data elements, output zero (previously, they output an expected value).  Constant Data elements output their defined value.
  • Once they are activated, the elements output their normal (computed) output.
  • Elements with Initial Values (e.g., Accumulators, Reservoirs and Expressions with initial values) output zero until they are first activated, and the Initial Value is not applied (i.e., they are not initialized) until they activate. (Previously, they output their Initial Value prior to activation).

  These new rules are discussed on page 9-31 of the GoldSim User’s Guide.  Note that due to these changes, some existing models may now behave differently.  Hence, if you are using conditional Container in your models, you are strongly advised to read this section and, if necessary, modify your models accordingly.

• You can now reference units in an expression without using curly braces.  That is, you can enter “10 m” instead of “10 {m}”.  The curly braces are still recognized (omitting them is optional).  The specific rules which must be followed if you wish to omit the curly braces are discussed on page 3-19 of the GoldSim User’s Guide.
• A new function (the Plume function) has been added which outputs a correction factor allowing you to compute the spatially variable concentration at the end of a Pipe pathway (accounting for transverse dispersion and a non-uniform source).  The Plume function is described in detail in page 4-66 of the Contaminant Transport Module User’s Guide.
• GoldSim can now create a Player file (see page 8-33 of the GoldSim User’s Guide).  Player files can only be viewed in the (free) GoldSim Player.  The Player is essentially complete, and is now being beta tested.  After the beta testing is complete, we will post the Player to the website (March or April of 2001).  If you would like to help beta test the Player, contact us at software@goldsim.com. 
• The GoldSim Dashboard Authoring Module allows you to create Player files that can be edited and run by others (Player files created without this module can only be viewed).  This Module is also essentially complete and is currrently being beta-tested.   Use of this Module will require a modification to user’s existing license agreements and an additional license fee.  It will be available in March or April of 2001.

Minor Changes and Bug Fixes

• Result elements now “remember” the last type of chart or table which was viewed.  For example, if you last viewed a distribution result element as a CCDF, the next time it is viewed, it will be displayed as a CCDF.
• You can now control the number of significant figures viewed in a result table (see page 7-15 of the GoldSim User’s Guide).
• Round and truncate functions only accept dimensionless arguments.
• New dialogs have been provided to assist in adding inputs for multiple discrete changes and triggers to an Element.
• When viewing the contents of a locked Container, the cursor takes on the appearance of a lock.
• A bug was corrected regarding how Stochastic elements were being correlated.  This bug resulted in actual correlations being slightly different from specified correlations.
• Entering Full Screen View in GoldSim 7.01 resulted in a crash.  This has been corrected.
• The following bugs in the Contaminant Transport Module were corrected:
  • Under some circumstances, GoldSim crashed when deleting species.
  • Pipe elements with a matrix diffusion skin layer crashed when simulating decay chains.
  • A bug in the manner that matrix diffusion is Pipes with retardation and anion exclusion  was simulated was corrected.
  • Inner and outer inventories for a Source were being reversed in 7.01.
  • Pipes with zero flow rates were being incorrectly computed.
  • The inner barrier inventory could not be released in the first timestep.
  • Source inventory cell fractions and matrix degradation rates where not updated dynamically if they were entered as expressions (rather than links).

Release Notes GoldSim 7.0

Corrections in GoldSim 7.01

• Corrected problems with Internet registration.
• CT Module: fixed problems for cell elements in conditional containers,  fixed problem with specifying time-varying degradation rate for source term, fixed problem with losing “Radioactive” setting for species.

Enhancements and Corrections in GoldSim 7.0

Major Changes

• The manuals have all been updated.
• Starting with this version, all copies of GoldSim will need to be registered (licensed) to a specific machine.  There are several different ways in which you can register GoldSim, all of which will be explained when you first try to run the program. In all cases, you will be required to enter a Registration Code.  All licensed users should have received a Registration Code via email.  If you are a licensed user and have not already received your Code, you can request one by sending an email to support@goldsim.com. Note that once you have registered GoldSim 7 on your PC, you can not move it to a different folder without getting a new Registration Code. Note also that a GoldSim copy that is only acting as a Slave does not need to be registered (unregistered copies can be run in Slave mode).  (For more information, see page 1-7 of the GoldSim User’s Guide).
• The basic GoldSim framework and the specialized GoldSim extension modules have been separated, with the modules (e.g., the Contaminant Transport module) now being provided as separate .DLL files.  Your particular license determines which of the modules are available to you.  If you are building a model that does not require an extension module, you can deactivate that module (via File|Extension Modules).  For example, if you do not need the Contaminant Transport features, you can turn off this module for a particular model, and the contaminant transport elements will be removed from the model. (For more information, see page 1-15 of the GoldSim User’s Guide)
• GoldSim now provides the ability to Lock or Seal a container, for QA purposes.  The contents of a locked container can be viewed but not edited (until it is unlocked via a password).  Nothing inside a sealed container can be changed without breaking the seal. GoldSim prompts the user before any changes are implemented to the contents of a sealed container (after which the seal is broken). (For more information, see page 4-9 of the GoldSim User’s Guide).
• All or part of your model results can now be exported (via File|Export|Results) into one of three formats: as an ASCII file, a binary file, or directly into an Access database. (For more information, see page 7-58 of the GoldSim User’s Guide).
• If a model has an invalid input, when you try to run it GoldSim will show an error message with a button that allows you to directly edit the element causing the problem.
• A number of command line parameters have been added which can be used to better control how GoldSim is run.  For example, one parameter causes the model to open, run, and immediately close.  This allows you to “stack” a number of runs in a batch file. (For more information, see page 6-16 of the GoldSim User’s Guide)

Minor Changes and Solved Problems/Bugs:

• GoldSim will no longer allow you to delete an ordinal set or a user-defined unit if it is currently being used in your model.
• The names of elements with attached notes are now underlined in the graphics pane (and appear as if they are a hyperlink).  Clicking on the element’s name displays the Note Pane.  Note that this means that you can no longer double-click on an element’s name in the graphics pane to directly edit it; instead you must Ctrl+double-click on the name.
• Added layout tools (via Graphics|Layout) and a new Layout toolbar to allow you to space and size elements and objects.
• Result elements now “remember” the type of display that was last shown (i.e., table or chart).
• Improved implementation of the Function-of and Affects calculations.  These are now carried out much more efficiently when dealing with large models.
• Tool-tips have been added to the Exposed Outputs dialog of a localized container to show the full path of the output.
• When viewing data tables for multivariate results, you can instruct GoldSim to show the full path of the output in the header to the table.
• A number of names (e.g., sin, cos) have now been protected so you can’t create elements with those names.
• Improved error handling for user-created DLL’s.
• Added the ability to send a GoldSim file via email (File|Send…).
• The Units dialog (for creating and activating units) has been streamlined and simplified.
• Simplified influence filtering dialog.
• You can now filter the outputs of conditional Containers (this was not previously available in the Define Filter dialog).
• Improved accuracy of the Laplace-transform solution for pipe and network elements.
• Added new capabilities to the Hyperlink object (the ability to jump to a particular container or element).
• Some problems with the Note editing window have been corrected.
• Corrected an error in the erf( ) built-in function.
• Corrected a problem related to pasting numbers with a comma format from a spreadsheet into a GoldSim table.
• Hidden influences can no longer be selected accidentally.
• A bug involving the matrix degradation rate in Sources was corrected.  In particular, if the matrix degradation rate was specified locally (with the Degradation Rate field) as an expression, the expression was not updated (the value at the first timestep was used for the entire simulation). 
• A bug involving associated cells was corrected.  In particular, of the model used substeps during the first fill timestep, and multiple packages failed during that step, solubility limits in associated cells were ignored.

Release Notes GoldSim 6.0

Enhancements and Corrections in 6.04.007

• After pasting numerical values in scientific notation into a Table element the auto-sorting did not work correct and mistakenly stored the numbers in an incorrect order.
• For contaminant transport solutions using Pipe or Network elements, where both parent and daughter species in a decay-chain had the same (non-zero) decay-rate, inaccurate outputs could be produced in GoldSim versions prior to 6.04.006.
• Some pipe-networks with complex interconnections were not being solved correctly.
• A bug which caused GoldSim to crash when using the ‘activation/deactivation results’ feature on a container level has been corrected.
• The Gamma distribution of the stochastic element mistakenly accepted invalid numbers for some of the inputs.
• Source element problems with disruptive events have been corrected.
• Linkage between External (DLL) pathways feeding Pipe elements was not functioning correctly.
• Effects of disruptions and time sub-steps on Source-term inner barriers were not being handled correctly.

Enhancements and Corrections in GoldSim 6.04

Over 100 new features and modifications have been made to GoldSim 6.04.  The key changes are highlighted below.

New Features

• Updated User Manuals.
• The Quantity element is now referred to as an Accumulator.
• We have slightly modified the way that conditional Containers are defined.  Please refer to Chapter 9 of the documentation for the details.
• We have modified the way in which Stochastics, Consequences and Delays can be triggered.
• You can now sort result tables in ascending or descending order by clicking on the header column.
• When plotting time histories of a vector, you can now display the mean time history of each item on a single plot (previously, you could only look at a single realization with all items, or the mean time history for a single item).
• Feedback links are now specified by placing a tilde (~) in expressions in front of the output for which you wish to use the previous value.  The user must do this explicitly.  GoldSim will no longer automatically create a feedback link when one is required.  Note, however, that this new method has several significant advantages, including 1) you can immediately tell which output is a feedback; and 2) when you copy or move a container with feedback links, the feedbacks are always preserved.  Please refer to the manual for details.
• You can now save the final values for outputs at the end of each phase.  This allows you, for example, to view a result distribution at multiple time points.
• Within the Simulation Settings dialog, we have simplified the manner in which you can specify a static simulation (with no timesteps).
• File elements now support distributed processor simulations, and use of local files.
• Pipe pathway elements have been augmented to support a distributed line source zone (parallel to the flow direction). 
• Improved efficiency of distributed processing simulations.
• Modified tab order in dialogs to be more logical.
• Improved accuracy of computed outflows and withdrawal rates from a Reservoir (taking into account that bound is reached in middle of timestep).

Solved Problems/Bugs

• Reservoir elements were not properly computing overflow rates and withdrawal rates if bounds were changing with time.
• A bug which caused nodes which are added to influences to “jump” erratically when they are added has been corrected.
• Several bugs related to moving elements have been corrected.
• The Extrema element was reporting incorrect values when operating on vectors.
• The Log-Normal distribution was displaying an incorrect mean if inputs had dimensions.
• Calculation of probability time histories sometimes reported an error if number of saved time histories was less than the number of realizations.
• It was not possible to repeat a single realization when running in Distributed Processing mode.
• Spreadsheet elements were not correctly handling spreadsheet entries formatted as currency.
• Numerous additional minor bugs have been fixed.

Enhancements and Corrections in GoldSim 6.03

New Features

• Updated User Manuals.
• We have changed how you specify the display units for a GoldSim element- they are now defined in the main dialog following the element description.
• When you edit an input field, simply Tab or click elsewhere in the dialog and your input will immediately be checked- you no longer need to click the OK button.  Prior to editing an input field, hold your mouse over it to see a Tool-tip showing the input’s value, or the error message if there is something wrong with it.
• Tool tips now have a light yellow background when you are in Edit mode, and a light green background when you are in Result mode.
• The little yellow or blue rectangles used to represent links to other Containers have been removed.  Now, input or output Ports having links to other Containers are outlined in black. To see all of the links for a Port, right-click on the Port and select the appropriate ‘display links’ option.
• Finally!  You can now copy information from a spreadsheet or a Word table and paste it into GoldSim grids (vectors, matrices, Tables). You can also copy tab-delimited text from an ASCII file and paste it. Also, the array-editing dialogs for matrices and tables are now resizable.
• So long as you elect to save at least two time-histories, GoldSim now automatically generates time-history statistics so that you can see percentiles in history plots.  This means that you no longer need to save all of your histories in order to generate these plots, which can save a lot of disk space for your GoldSim file.
• If you are browsing your model in Graphics-view, there are now ‘back’ and ‘next’ buttons similar to a Web browser.
• The ability to define Conditionality for Containers is now fully functional, and is described in the Manuals. However, we’re still working on this and will enhance it a little more in the next GoldSim version.
• You can now minimize GoldSim while running a simulation, by clicking on a button in the ‘Running model…’ dialog.
• If you are editing your model, and want to know what results you have selected to save, you can display them in bold by selecting a new option in the View menu.
• You can enable or disable saving all results within a given Container from a new option within the Container’s property dialog.

Solved Problems/Bugs

• Numerous minor bugs have been fixed.
• A bad bug in the Selector element was repaired.  This bug could corrupt the GoldSim file if you deleted an input to the Selector element.
• If you selected Latin hypercube sampling, there was a bug that prevented GoldSim from repeating a specified realization from a Monte Carlo simulation.  This is now fixed.

Enhancements and Corrections in GoldSim 6.02

New Features

The GoldSim 6.02 install process will automatically upgrade any necessary Windows DLL files on your system. It will add support for ODBC database connectivity if it is not already present.

• Updated User Manuals.
• You can reference Table elements like functions within expressions.
• Major improvements to result-processing, use of Styles for charts, etc.
• Contaminant transport users can have multiple ‘Reference fluids’ to define variable solubilities within a single cell network.

Solved Problems/Bugs

• Multi-processor network solver problems have been resolved.
• Numerous minor bugs have been fixed.

Fun fact: GoldSim was initially released as GoldSim 6.0, a tribute to its predecessor RIP (Repository Integration Program), a DOS program retired at version 5.2. See our blog for a more detailed history of GoldSim.
