I'd prefer to avoid adding more and more data in this class. Adding
functions is not a problem. You could add previous penetration to
MindlinPhys, it would make more sense since only this sort of
interactions need the value. Deriving a new Ig from ScGeom is maybe
better in terms of design, it seems a bit overkill to me though.

Ok, no problem, I need it for energy computation. I was asking because
I thought it could have been similar to previousNormal, but in fact
that is needed to all the laws.
What about simply using currentUn-incidentVelocity.dot(normal)*dt by the
way?
I removed previousNormal. :-)
Btw, in ScGeom are you getting rid completely of rotateAndGetShear
function? Or would you think to keep it somehow?
Its removed as well. I adapted your law with the new rotate(Vector3r)
function.
