Error: “Process ‘3dnms’ terminated abnormally” in Ansys Maxwell

[shinob01]

Hello

I am currently working on the simulation of an axial flux permanent magnet (AFPM) motor in Ansys Maxwell 3D. I encounter the following error during the simulation:

         Error: Process '3dnms' terminated abnormally. It may have run out of memory or could have been killed by the user.

The error appears only when the full model is simulated, including the rotor (ring on top) and the permanent magnets (red and blue objects). If I reduce the model by excluding these components, the simulation runs without errors.

What I have tried so far:

• Reducing the mesh density for all objects

• Limiting the number of mesh elements in critical areas

• Adjusting HPC settings

Unfortunately, the error persists.

Has anyone encountered a similar issue or could provide guidance on how to handle this memory-related problem? Any suggestions for resolving this error while keeping the full geometry would be greatly appreciated.

hank you in advance for your help!

What is the memory usage running the full model?
