Re: total formulation + modifying friction?

 


Is this correct (regarding Dem3DofGeom_SphereSphere):
1. Initial orientations ori1 and ori2, are never modified.
They are modified when there is plastic slip -- see below.
I don't see ori1/ori2 modified anywhere in the code, but cp1rel is taking care of the reference change, yes?
Mmmh... I'm really lost. How can friction change the force in that case?

B.
