Studio 8 Simulation Engine Features - Version History
The Studio 8 Simulation Engine introduces a new scheme for distribution of software created with the Studio 8 SDK.
Find the full list of Service Releases and Feature Packs launched for Studio 8.
Studio 8 Simulation Engine, Service Release 4 with Feature Pack 2
Released June, 2010
The fourth service release of Studio 8 Simulation Engine accompanies Service Release 5 of Studio 8 SDK 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 Simulation Engine, Service Release 3 with Feature Pack 2
Released March, 2010
The third service release of Studio 8 Simulation Engine accompanies Service Release 4 of Studio 8 SDK and contains a few improvements and bug fixes:
Improvements:
- Improved the multi-core processing capabilities of Powersim Studio Simulation Engine.
- Improved calculation logic to increase simulation performance in Powersim Studio Simulation Engine.
- The time used to close project files is now in some cases substantially reduced.
Bug fixes:
- Fixed a problem that could cause undetermined behaviour when using the DISTRIBUTE or DISTRIBUTETOFRONT flow functions with integer parameters.
- 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.

Studio 8 Simulation Engine, Service Release 2 with Feature Pack 2
Released January, 2010
The second service release of Studio 8 Simulation Engine accompanies Service Release 3 with Feature Pack 2 of Studio 8 and Service Release 2 with Feature Pack 2 of Studio 8 SDK. The release introduces Feature Pack 2 for Simulation Engine 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 Studio 8 SDK solutions where Feature Pack 2 features have been used and Studio 8 models where Feature Pack 2 features have been enabled.
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 Simulation Engine, Service Release 1 with Feature Pack 1
Released October, 2009
The first service release of Studio 8 Simulation Engine accompanies Service Release 2 of Studio 8 and Service Release 1 of Studio 8 SDK and contains a number of bug fixes.
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 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 Simulation Engine Administration Utility where the Upgrade button was disabled on Windows Vista and Windows 7.

Studio 8 Simulation Engine with Feature Pack 1
Released July, 2009
The first release of Studio 8 Simulation Engine accompanies Feature Pack 1 of Studio 8 and Studio 8 SDK (and therefore includes Feature Pack 1). The release contains some new features.
New Features:
- Supports solutions created in Studio 8 SDK and models made in Studio 8. Also supports Studio 8 SDK solutions where Feature Pack 1 features have been used and Studio 8 models where Feature Pack 1 features have been enabled.
- New scheme for distribution of software created with the Studio 8 SDK
