Error Running eigensolver (ABAQUS/standard rank 0 encountered a SEGMENTATION FAULT)

[jrb26]

Hello, I've encountered the following error when running a natural frequency eigensolver job.

Error:
---------- RUNTIME EXCEPTION HAS OCCURED ----------
*** ABAQUS/standard rank 0 encountered a SEGMENTATION FAULT

I have a single mesh (converted from an STL into geometry - no issues with meshing) with a simple encastre BC on one of the faces of the geometry.
I am currently using a computer with an AMD Ryzen 5 1600x w/ 1060 3gb. However, I have got the exact same model and job configuration to work on a different computer with an Intel i7-11370h w/ Nvidia MX450. Could this factor in? Does Abaqus not like AMD CPUs?

For my current setup, I installed Abaqus on a my E:\ drive rather than my C:\ drive (as I was low on space), which I thought I did correctly, however, looking at the EXCEPTION file that was created, it looks like the job is trying to access directories that are located on my C:\ drive. Is this relevant? I only have ~3GB left on my C:\ drive, perhaps its running out of memory?

I'm relatively new to Abaqus, so any suggestions would be really helpful, thanks in advance.

[FEA way]

However, I have got the exact same model and job configuration to work on a different computer with an Intel i7-11370h w/ Nvidia MX450.

Segmentation fault usually means a bug in Abaqus or an issue with the computer (the latter might be the case here if the same Abaqus version was used).

I only have ~3GB left on my C:\ drive, perhaps its running out of memory?

This would normally cause a different message but it's often the case that analysis fails because of insufficient disk space for scratch data.
