@nrbertin this is a very simple addition to exadis to output the full plastic distortion tensor, as I could not find this option in the code. It is of course redundant to have plastic distortion, strain and rotation, but I thought this is cleaner. Happy to remove one of them if you prefer.

As can be seen from the commits, AI tools were used, but as can also be seen, the codebase change is minimal!

Accumulate the symmetric plastic strain (Eptot) and plastic spin (Wptot) per step in the driver, expose them along with the full plastic distortion tensor (Pdist = Eptot + Wptot) as output fields, and persist Eptot/Wptot across restarts.
