A Dinesh proposed the following answer:
Hi Lip,
That's what Jan is explaining, I guess. For a sphere-sphere interaction we have
the contact force dependent
on the amount of overlap. But in the case of polyhedra, one needs to check the
amount of volume. And the
force is proportional to the overlap volume.
See figure 1 of reference [1]. In this figure the author Herrmann describes
the interaction between two polygons (It is 2d,
so he considers area, in place of volume). I think the same principle goes with
sphere and polyhedra interaction.
Can Jan conform? Thanks
