When used from command line to simulate an FMU on Linux, the created temp directory /tmp/tmpNNNNNNN is not removed on exit if an exception is thrown. I looked at the code here: https://github.com/CATIA-Systems/FMPy/blob/main/fmpy/simulation.py#L757 and you should put that in a try/else block otherwise the cleanup will be skipped!
