FMI Support Limitations

Last Modified: June 10, 2021

Early Access FMI support has several limitations.

  • All FMI numeric data types are supported but cast to doubles internally.
  • String variables are not accessible.
  • A DefaultExperiment section with a non-zero stepSize is mandatory. Models without the DefaultExperiment section will fail to run.

    Note  

    An example of a working stepSize is <DefaultExperiment stepSize="0.01"/>.

  • Changing stepSize in VeriStand is not supported. The only way to change stepSize is by modifying the modelDescription.xml file inside the FMU.
  • FMU logging is not supported.

    Minimal logging to the console will be done in the case of fmi2Fatal results.
