This is just image of the crash file . Could you please share the file itself so that developers can look into ?

[Naveen-Kumar-B]

Are you asking about AnsysWBDumpFile.dmp file.? If im not wrong @dipinknair

Are you asking about AnsysWBDumpFile.dmp file.? If im not wrong @dipinknair

Yes

[dipinknair]

@Naveen-Kumar-B . I have teste the behavior and can confirm that crash is happening. But unfortunately this is directly related to Mechanical rather than PyMechanical. You can easily verify by running your script in batch mode with mechanical.
I will follow up with Mechanical development team to create a bug so that this issue is fixed in future Mechanical version.
