Hello guys! Hope you are having a great time all together :-) Could not we
organize a course/meeting among Yade users/dev? I have already mentioned to
Vaclav that this would be a nice idea. I hope it will happen at some point
in the future.

Thanks for suggestions, I will try it. Actually the elastic part, once
calling ScGeom::updateShear, is already stored in ScGeom shear variable.
Perhaps the easiest thing would be to create a new variable into the contact
law which stores what is returned by updateShear, and, as you suggest,
simply avoiding to pass it through the failure criterion.

cheers, Chiara
