4.6.4 (build 8004, July 26, 2017)

3D Animation

  • Fixed: Range issue in Spot Angle.

Code Generation

  • Fixed: Directly mapping to an R(ate)-variable if a submodel takes the integral/previous of an input.
  • Fixed: Initial equations in a FMU cannot influence initial states.
  • Fixed: Crash when running a generated FMU in a FMI 1.0 master simulator.
  • Fixed: FMU 2.0 Export: Table2D implementation for source code FMU does not work on Linux/MacOSX


  • Reference Manual: Fixed: Unclear statement about 'while do' and 'reapeat until'.
  • Reference Manual: Fixed: Orientation of Euler angles in 3D animation window (ZXZ instead of XYZ).


  • Fixed: Not saving a model when closing 20-sim during a simulation.
  • Fixed: A issue when writing a data file of multiple run results (parameter sweep).
  • Fixed: A issue that unnamed nodes can generate instructions for a continuous time block instead of the corresponding discrete block.
  • Fixed: A crash during a multiple run simulation with parameter sweep.
