hi Liqing,
I finally gave Law2_ScGeom_CohFrictPhys_ElasticPlastic a try in the
cohesive triaxial test (with moment law), but I didn't see any problem.
How is the situation on your side?

Hello Vaclav,
You are right. I see the force is nan indeed. Thank you so much. Thank
you for so warm help. I will check the contact law carefully. Thank
you again.
Best
