    Status: Open => Answered

Bruno Chareyre proposed the following answer:
Hi,

This:
triax.stressMask = 0
triax.goal1 = 0.00

Implies that the goal is now to return to the reference
(initial/undeformed) state.  That's what the engine is doing:
uncompacting, then stress goes back to zero.

If you want no deformation after  stressMask = 0 then you need:
triax.goal1 = triax.strain[1] #goal = current

or:
O.cell.trsf=Matrix3.Identity #current = reference
triax.goal1 = 0.00

Cheers

Bruno
