Hello,

I've generated a FMU from Python script that I'm trying to deploy in Altair. But I'm getting this error (see attached image) which I've been trying to detect the source of.

[VERBOSE][FMICAPI] Calling fmi2GetModelTypesPlatform

Thanks in advance for any help.

    Hi Blaise. If your FMU was created succesfully on another tool, can you look at the directories it contains, please?

    If your goal is to run the FMU in a Twin Activate simulation, have you tried running it on the FMU block? Where in Twin Activate are you running the Python script (in the Python command window or in the ExecPython block)?
