Studio 8 SDK Service Release 4 with Feature Pack 2

Released June, 2010

The fourth service release of Studio 8 SDK accompanies Service Release 5 of Studio 8 and contains a couple of bug fixes:

Bug fixes:

Fixed a problem that in some cases could cause undetermined behavior when running simulations with series variables on multi-core computers.
Fixed a problem that caused incorrect calculation of delay functions and other state functions using delayed input from levels.

Studio 8 SDK Service Release 3 with Feature Pack 2

Released March, 2010

The third service release of Studio 8 SDK accompanies Service Release 4 of Studio 8 and contains a few improvements and bug fixes:

Improvements:

Improved the multi-core processing capabilities of Powersim Studio 8 Simulation Engine.
Improved calculation logic to increase simulation performance in Powersim Studio 8 Simulation Engine.
The time used to close project files is now in some cases substantially reduced.

Bug fixes:

Fixed a problem with ModelVariable::PublicChildren that could cause undetermined behavior when not all of the variable's children were public.
Fixed a problem that in rare cases caused binary operators (e.g. +, -, *, /) to not work when one of the operands was a result of a FOR loop.
The SAP BI Dataset no longer deletes all data before the first time period of the simulation when writing data to SAP BI.
Fixed a problem that could cause the random functions to return the same random sequence for a subsequent run if the previous run completed in less than 0.05 seconds.
Fixed a problem that could cause undetermined behaviour when using the DISTRIBUTE or DISTRIBUTETOFRONT flow functions with integer parameters.

Announcements:

We are proud to announce that Powersim Studio 8 has been certified for integration with SAP BI.

Studio 8 SDK Service Release 2 with Feature Pack 2

Released January, 2010

The second service release of Studio 8 SDK accompanies Service Release 3 with Feature Pack 2 of Studio 8, and introduces Feature Pack 2 for SDK users with Support and Upgrade Agreement (SUA). It also contains an improvement and some bug fixes available to all users.

New Features:

Powersim Studio Simulation Engine now takes advantage of multi-core processing when running simulations.
Supports models created in Studio 8 where Feature Pack 2 features have been enabled. These models typically use one of the new functions: SERIESINITIAL, SERIESFINAL, CURSERIESLOOKUP, and PREVSERIESLOOKUP.

Improvements:

The time used to load large project files is now in many cases substantially reduced.

Bug fixes:

Fixed a problem with accumulated and average series variables of integer type that prevented access to their value history.
Fixed a problem that prevented finding units given their plural name.
Fixed a problem with the SECOND function when used in projects with 'Enforce time unit consistency' switched off.
Fixed a problem experienced when writing data to a read-only workbook through a Spreadsheet Dataset.
Fixed a problem with the FILLINZEROES flow function that could cause undetermined behaviour when one of the dimensions in the associated level used negative indices.

Studio 8 SDK Service Release 1 with Feature Pack 1

Released October, 2009

The first service release of Studio 8 SDK accompanies Service Release 2 of Studio 8 and contains a number of bug fixes as well as a minor improvement.

Improvements:

A project file for Microsoft Visual Studio 2005 (or newer) is now provided for the SimInspector sample.

Bug fixes:

Fixed a bug that sometimes caused problems when using the Powersim Studio Simulation Engine in a multi-threaded environment.
Fixed a problem that could cause ModelVariables::FindFromId to find variables not contained in the collection.
Fixed a problem that could cause ModelVariables::Find and ModelVariables::FindFromId to find non-public variables when invoked on a collection of public children.
Simulation::State now returns simFinished rather than simRunFinished when a simulation is stopped due to a STOPIF function.
Fixed a problem that in some cases caused levels using the XLDATA function to not be initialized correctly.
Fixed a problem with the Database Dataset that sometimes caused wrong values to be read or written when the simulation horizon was less than a year.
Fixed a problem with the Powersim Studio SDK Administration Utility and the Powersim Studio Simulation Engine Administration Utility where the Upgrade button was disabled on Vista and Windows 7.
The precompiled executable for the SimInspector sample (SimInspector.exe) now runs on 64-bit versions of Windows.

Adaptations:

The "Studio Simulation Engine" libraries have changed name to "Powersim Studio Simulation Engine".
The "Studio Engine Controls" library has changed name to "Powersim Engine Controls".

Studio 8 SDK with Feature Pack 1

Released July, 2009

The first release of Studio 8 SDK accompanies Feature Pack 1 of Studio 8 (and therefore also includes Feature Pack 1 of the SDK). The release contains several new features.

New Features:

Supports models created in Studio 8 Enterprise. Also supports Studio 8 models where Feature Pack 1 features have been enabled. This means that you can use series and startup variables. You can also use the improved functionalities of the XLDATA function and the Database Dataset. Furthermore you can use the new functions IRR and ARRNPV.
New scheme for distribution of software created with the Studio 8 SDK
New Simulation methods: ActivateRun, CanActivateRun and SaveRun
New ModelVariables methods: Find and FindFromId
New ModelVariable property: Id

Adaptations:

The "Powersim Simulation Engine" libraries have changed name to "Studio Simulation Engine".
The "Powersim Engine Controls" library has changed name to "Studio Engine Controls".
