The major new features in Simantics System Dynamics 1.9 are:

  • XMILE import/export support
  • Internal custom solver improvements:
    • Standard java.lang.Math functions made available to the solver (#5769)
    • vector*matrix is now supported (#5681)
    • if-then-else statement is now fully supported, Ecotax sample model now works (#5777)
  • General bug fixes and optimizations
  • New deployments: Simantics System Dynamics is now built as 8 separate packages with 3 varying aspects:
    • 32-bit and 64-bit
    • with and without included Java Runtime Environment (JRE)
      • Including JRE adds 43-50 MB to the package
    • with and without built-in OpenModelica 1.9.2 (OM)
      • Without OpenModelica it is possible to install Sysdyn into any location on hard drive (previous long path problem)
      • Including OM adds 433 MB to the package
      • The package with only the internal solver is "only" 117 MB without JRE.
      • Playback and sensitivity experiments do not work without OM, other functionality should be fine
