Another problem is how to distinguish between ball-to-ball contact and
ball-to-wall contact, the material of balls and walls are all both
FrictMat. And, for the Hertz-Mindlin contact law, only the
Ip2_FrictMat_FrictMat_MindlinPhys of IPhysFunctor and
Law2_ScGeom_MindlinPhys_Mindlin of LawFunctor can be used, ie
InteractionLoop(
[Ig2_Sphere_Sphere_ScGeom(),Ig2_Box_Sphere_ScGeom6D()],
[Ip2_FrictMat_FrictMat_MindlinPhys(en=en,eta=eta,krot=krot),Ip2_FrictMat_FrictMat_MindlinPhys(en=en)],
[Law2_ScGeom_MindlinPhys_Mindlin()],
So how to distinguish between ball-ball contact and ball-wall contact,
so that the contact between the wall and the ball is set to be
frictionless and anti-rotational.
