Studio 10 SDK Service Release 2 with Feature Pack 1

Released December, 2015

The second service release of Studio 10 SDK accompanies Service Release 4 of Studio 10.

Improvements:

  • When a range defined by XLRANGE or DBRANGE yields no elements, a single dummy element is generated (since a range in Powersim Studio cannot be empty). The name of this element text has changed from "Error: No elements" to "<No Elements>".

Bug Fixes:

  • The Production.sip simulation project file included with the ASP.NET example no longer contains a connection to SAP BI, allowing the example to work with the academic editions of Studio and Studio SDK.

Announcements:

  • When calling the SimulationEngine::OpenProject method from .NET projects in Microsoft Visual Studio 2015, without specifying a value for the optional ReuseExisting parameter, the generated code will in some cases pass False instead of True to the Simulation Engine, and you will receive a System.ArgumentException with description: "The value for the 'ReuseExisting' parameter is not valid." To work around this you will have to specify a value for all the parameters of the SimulationEngine::OpenProject method.
  • If you have the so-called Click-to-Run installation of Microsoft Office 2013 or Microsoft Office 2016, database connections to Access from Powersim Studio Simulation Engine will not work. You can get around this issue by rather installing the MSI installation of Microsoft Office (if available to your organization), or by installing the Microsoft Access 2010 Runtime (available from Microsoft's download pages) in addition to Office 2013/2016.

Studio 10 SDK Service Release 1 introducing Feature Pack 1

Released July, 2015

The first service release of Studio 10 SDK accompanies Service Release 2 with Feature Pack 1 of Studio 10, and introduces Feature Pack 1 for SDK users with Support and Upgrade Agreement (SUA). It also contains an improvement and a few bug fixes available to all users.

New Features:

  • Supports models created in Studio 10 where Feature Pack 1 features have been enabled.

Improvements:

  • The use of stack memory is reduced, avoiding problems when running in processes where stack memory is limited (e.g., IIS).

Bug Fixes:

  • Fixed a problem that could cause the First and Last parameters of the SampleTimes property of the ValueHistory object to be ignored.
  • Fixed a problem that caused the wrong data provider to be used when connecting to an Excel file with extension ".xlsx" through a Database Connection.
  • Fixed a problem that in some cases caused silent installations of Studio SDK to fail because the specified command line parameters were discarded.

Studio 10 SDK Major Release

Released March, 2014

The first release of Powersim Studio 10 SDK contains some new features and improvements, and a few bug fixes. In addition, we have made some changes to the licensing scheme for Studio SDK.

Licensing Scheme Changes:

  • The Premium edition has been discontinued, and the former Premium functionality is now available (or partly available) in the other editions.

New Features:

  • Supports models created in Studio 10.
  • Models authorized with Studio SDK 10 can now be used in desktop applications through the new free Studio Simulation Engine Workstation.
  • Simulation::ControllableRanges is now available in all Studio SDK editions.

Improvements:

  • When accessing the Simulation Engine Object Model from within Studio, you now get the simViewAccess access rights if View Access is available for the project (in Studio).

Bug Fixes:

  • Fixed a problem that could cause the ValueHistory objects returned from Simulation::AcquireValueHistory and ModeVariable::AcquireValueHistory to become invalid. This occurred if the 'simSummaryAuto' summary type was used and the source variable was a series variable with another series type than First. Note that 'simSummaryAuto' is the default summary type for this method.
  • Fixed a problem that prevented accessing controllable ranges when accessing the Simulation Engine Object Model from within Studio.
  • Fixed a problem that in some cases prevented the SimulationEngine::OpenProject method from providing extended error information.
  • Fixed various problems related to reference variables.

Announcements:

  • The Old Powersim Engine COM Interfaces and the Powersim Engine ActiveX Control have been discontinued in this release of Powersim Studio SDK.
