Hi Jérome, There is a problem in this commit, see lines [1]. You replaced: siso = goal1 + goal2 + goal3 by siso = abs(goal1 + goal2 + goal3)
So now it is impossible to define isotropic traction as a target state. Stresses and strains have signs, there should not be any abs() function applied on them except in a few special cases, else it breaks the algorithms. Cheers.
