OK, I read that paper, it is not different (in general) from what should have been Dem6DofGeom which I never implemented, but I had preliminary implementation of bending&twisting in SpheresContactGeometry (the code is still in there, commented), with a demonstration of twisting chain of 20 spheres (pendulum-like thing). Though now I think that rather than implementing Dem6DofGeom, a unified geometry classes should be made, where the displacement computation wil be done in the geometry functor rather than in constitutive law or in the IntrGeom class itself (like Dem3DofGeom does). That would allow to switch between incremental and absolute formulations by switching Ig2 functors, with no change to the law itself. Also, virtual function call would be avoided. I will try to blueprint that one and perhaps prototype it; if someone can help, he/she will be the most welcome.
