Manu is still having a problem:
HI Jan

Thank you for the feedback. I am actually interested in exporting the
particles to ABAQUS, so that I can understand the deformation and
non-linear behaviour of the particles (metal powder) during compaction.

If you can guide me to what command I can use, that would be of great
help.

Thanks
Manu
