All I would need is the relativeVelocity to compute incidentVn and
incidentVs, having the normal. If I inherit from ScGeom, relativeVelocity is
not a member of it. So how would you access it?

Besides, rotateAndGetShear returns the shear increment, so in the contact
law I could get the relativeVelocity from it, but as you already say it
would mean computing the same value twice.

Thanks. Chiara
