Yeah, I got a banana too, and compilation went to plugin24 in the 
meantime... (matter of days before I get a decent pc).

Yes, I wouldn't have notice anything without changing friction.
Still wondering if it couldn't result in different force orientation in 
some cases (after many iterations), since cp1rel was based on wrong 
values. Not sure.

Glad to help. :)

Indeed, the return value 2*diff.norm() was nonsense but finite. I guess 
you used that one for plastic dissipation?
By the way, there are a few useless operations in the whole dem3DOF 
thing (like sqrt computed twice here and there, or diff.norm() computed 
but not used - and equivalent to (currDist-displacementTMax)). Ok, to 
fix this at the same time?
