Twin Builder Options: Modelica Compiler Options

Use these options to define settings for the compilation of Modelica models.

• Memory Usage Limit – Limit the use of memory by the Modelica compiler. Increase this number when model compilation fails due to memory size.

• Modelica C-compiler – Set the C++ compiler used to compile Modelica models.

  • GCC (internal) – Default. Use the Gcc compiler from <Installpath>\Common\MinGW-5.1.0.
  • GCC (user defined) – Use the Gcc compiler from the MinGW location specified in the text control. To change it, click .
  • Visual Studio – Use the C++ compiler from an installed Visual Studio. For a list of supported Visual Studio versions, see Program Requirements in the Introduction to the Twin Builder C Interface section.
    Note:

    If the Modelica model incorporates externally compiled C-code (external DLLs), compile the Modelica model with a Visual Studio C++ compiler.

• JRE Location – Define the location where the Modelica compiler looks for the Java Runtime Environment (JRE).
  • Use Internal JRE – Use the JRE included in the installation.
  • Use JRE from JAVA_HOME – Determine the location of the JRE by the JAVA_HOME environment variable.
  • User-defined location – Access the JRE from the location specified in the text control. To change it, click .
    Note:

    • Twin Builder requires 64-bit Java when using a JRE other than the one included in the installation.

    • Changes to the location of the JRE used for the Modelica compiler take effect after restarting Twin Builder.
• Advanced Options – Define non-standard settings for the Modelica compiler.
  • Advanced Command-Line Options – Settings for non-standard features of the Modelica model compilation. Those settings can be obtained from Modelica support on a case-by-case basis.
  • Advanced Settings – Other advanced settings.
    • Keep Temp Files – Keep temporary Modelica files that are generated during compilation in a separate folder. Use this setting to collect all files necessary for the investigation of a support ticket. The default is No.
    • Allow Lib Version Mismatch – If the library version of an instantiated model is lower than the required version specified in an annotation, the Modelica compiler issues a warning instead of an error. The default is Yes.

• Messages & Diagnostics – Define the setting location for additional information during model compilation.
  • Message Level – Define the level of messages displayed in the Message Manager pane during the compilation of Modelica models.
    • Errors – Only errors appear in the Message Manager pane.
    • Warnings – Errors and warnings appear in the Message Manager pane.
    • All – All messages appear in the Message Manager pane.
  • Log Level – Choose the level of detail that appears in the Modelica compiler log file. The default is Errors.
  • Diagnostics – Generate additional diagnostics information about the Modelica model. The default is OFF.
  • Save To – Define the location where the Modelica compiler stores additional information during model compilation, and the diagnostics. The default location is the temp folder defined in the General > Directories page. The diagnostics and compiler log information display in a browser when you double-click the messages in the Message Manager pane.
