Forces themselves (Scene->forces) are really reset, but we keep force of the interaction in NormPhys::normalForce and shear force in NormShearPhys::shearForce. The functor is responsible of filling those values at every step.
We don't same any more history, in that case you would need to derive *Phys (e.g. MindlinPhys) from NormShearPhys and store it in there.
