Hii there!

Does anyone maybe knows and can please tell me how and where to fix this error "Exception: Failed to instantiate model" and [ERROR] fmi2Instantiate: Failed to parse the model description, which occurs in the FMPy generated notebook, when running:

The FMU is not valid. Problems:
ModelStructure/InitialUnknowns does not contain the expected set of variables. Expected {TMeanAir} but was {}.

How do I get the variables in the ModelStructure in the ModelDescribtion.xml?

Thx in advance and looking forward!

nice greets burns

Could you share any *.err, *.log files, from the FMU run? Also, have you considered using another master algorithm (e.g. PyFMI) just to see if you can reproduce the problem?

I added the error log in the orignial post now. Haven't tried it with PyFMI with this specific version, but maybe going to if nothing else solves the errors.
