  3. I try to run a Functional Mock-up Interface (FMI) Co-simulation in CFX. The FMU was written in Modelica and exported by Dymola. When I run the simulation, CFX reports an unspecific error with the FMU and stops. What could be the reason for this?

      If you see an error message that is similar to this one for a Dymola-generated FMU: ERROR #999100420 has occurred in subroutine fmi2InstantiateF. Message: Functional Mockup Unit (FMU) error: – FMU instance : NameOfFMU – FMU error : fmi2Error the reason could be that you compiled the FMU in a way that requires a Dymola license for the execution of the FMU and you don’t have access to the required license. In this case, the modelDescription.xml will contain an entry like generationTool=”Dymola Version 2019 (64-bit), 2018-04-11 (requires license to execute)” Instructions on how to compile the FMU such that no license is required for the execution of the FMU can be found in the Dymola documentation.
