🐞 Description of the bug

Hello

We have this issue with the attached pymech script.

It all works ok inside standalone mechanical scripting console (right image below), but when we run it from vs code we see in the saved mechdat (Incident wave and physics region) this weird error (see left image below).

Thank you

Erik

@ekostson I have confirmed the reported behavior through testing. Since this issue appears to be directly related to PyMechanical embedding and how Mechanical scripts are executed in batch mode, I would recommend running the script in batch mode using Mechanical as a next step.

If the script executes successfully in batch mode, I can investigate the issue further on my end. However, if the same behavior is observed in batch mode, this would indicate that the root cause lies within Mechanical itself, and I would recommend filing a defect with the Mechanical team for further investigation
