   I suppose it should work without it. You can make a PR and see if the test pass.

   I know that I added it - at that time I did not ask why it is not working - however, it is still failing; see the checks of my test branch at: https://github.com/syntron/OMPython/actions/runs/19550820822/job/55981548974

   Error message:

   FAILED 😰  tests/test_FMIImport.py::test_FMIImport - OMPython.ModelicaSystem.ModelicaSystemError: Error executing 'buildModel(M_me_FMU, variableFilter=".*")': OMC error occurred for 'sendExpression(buildModel(M_me_FMU, variableFilter=".*"), True):

   The generated Modelica code from FMU uses reinit inside algorithm section which is not allowed anymore. So in order to run this one need to use --allowNonStandardModelica=reinitInAlgorithms.

   I guess this won't fix since we use OMSimulator now for importing FMUs. The importFMU API is kind of depreciated and there are no future plans for it.

   If FMU import in OpenModelica is depreciated what would be the recommended way to load an FMU and extend it by additional code using OpenModelica? As I read the description of OMSimulator is mainly for simulating an FMU; not for the extending part ...

    I have no idea if we are going to fix FMI import in future. But for now in order to make it work one need to use --allowNonStandardModelica=reinitInAlgorithms.

    That's a job for MAP-Lang/MAP-Lib. We're working on it.
