There seems to be a problem with ABAQUS export for certain periodic meshes in v6.2.2501 (which I did not encounter in v6.2.2405).
Attached is a small python sequence that seems to lead to a valid .vol file, which, however, gives rise to a Segmentation fault when trying to export to an ABAQUS mesh under Linux 22.04.5 LTS (Kernel 6.8.0-52-generic).
