Hi Henning,

First off, thank you for writing and sharing this useful git repository. I have some newbie questions.

How were your *.fmu files created?
Can you clarify a bit the communication data flow between the FMU and FOAM?

Regards,
Greg

the fmu files were created with openmodelica you find the generation script here:testsuite/test-TempControlFlange/FMUGen.mos
In the case that OpenFOAM runs the FMU (https://github.com/DLR-RY/FMU4FOAM/tree/master/examples/TempControlFlange)

OpenFOAM starts a python interpreter that executes the specified file in the controlDict

FMUSimulator
{
    type            FMUSimulator;
    libs            (pyFMUSim);
    pyClassName     controlledTemperature; <---
    pyFileName      controlledTemperature; <---
}

The data is then exchange via json (details see):
