2025 R1 01/14/2025

Features Updated

  • PACZ extraction directory for the MCRE remote "Run On" feature for Linux is now configurable.
  • Added support for MATLAB versions 2024a and 2024b.
  • Added support for SolidWorks 2024.
  • Added support for CATIA V5 2024.
  • ModelCenter Help is now available as part of the online Ansys Help system.
  • Support for Java 8 in ModelCenter products is now deprecated. Support for Java 8 will be removed in the 2025 R2 release.

Issues Addressed

  • Resolved an issue where a published, expanded PACZ could not be inserted into a ModelCenter workflow.
  • Resolved an issue where ModelCenter would not share licenses when starting MCRE instances via an SSH connection.
  • Resolved an issue relating to the Java Selection Tool where a user could not correctly set the required Java related environment variables.
  • Clarified error messaging when attempting to connect to MCRE on Linux over SSH.
  • Resolved various issues with the PACZ Publisher and long variable names and aliases.
  • Resolved an issue where assemblies could not be deleted from workflows.
  • Resolved an issue where attempting to run an embedded optimization that used the Darwin algorithm would fail.
  • Resolved an issue where component Plug-Ins could leak processes or files.
  • Resolved an issue where attempting to use the optiSLang OCO algorithm with discrete design variables could cause an error stating "Specified cast is not valid."
  • Resolved an issue where the optiSLang Adaptive DOE could run with design points that did not include the desired range.
  • Resolved an issue where the optiSLang Adaptive DOE could not run design variables with enumerations containing levels.
  • Resolved an issue where the optiSLang Adaptive DOE would not work with design variables that included non-double types.
  • Resolved an issue where the optiSLang OCO algorithm could perform more than the maximum number of evaluations.
  • Resolved an issue where the optiSLang OCO algorithm would attempt to write logs to a hardcoded path at the root of a user's hard drive.
  • Resolved an issue where optiSLang optimization algorithms would error when there were failed runs in the Trade Study.
  • Resolved an issue with the Excel Plug-In where macros would not execute if the Excel workbook being referenced contained spaces or parentheses in the filename.

Known Issues and Limitations

  • 3D Scatter or Scatter Matrix plots may error and display incorrectly with all data aggregated along a single axis if the mouse pointer is hovered over the graph while it is being generated.

    Workaround: Re-load the plot, making sure to not hover the mouse pointer over the plot while it is loading.

  • When performing a trade study using parallelization, Minerva-based components can fail and/or error.

    Workaround: Disable trade study parallelization.

  • Attempting to load a file that was found via the search functionality in the Minerva Import Plug-In will cause an error.

    Workaround: Browse to the file and select it without using the search.

  • ModelCenter may attempt to check out too many SimultaneousWorkflowExecution licenses when:
    • Using parallelization to perform a trade study on a workflow that contains a component that also has parallelization enabled
    • Running an Execution Plan multiple times in parallel.
  • When viewing the results of the optiSLang Post Processing Plug-In using the Data Explorer in ModelCenter, the Trade Study name is incorrectly shown as the name of a temporary file instead of the original Trade Study file name.
