Klaus Thoeni is still having a problem:
Ok, this explains why the clump runs through. However, running the
script with E=2e5 shows oscillating contact forces for the clump (which
at the end give good results for this case). This means again in order
to get realistic forces the overlap at the contact must be smaller than
the radius used for the spheres in the particles. So it might be better
to use bigger particles for generating the clump. And this might be as
well one reason why normal spheres run through facets. If the overlap
becomes bigger than the radius the sphere basically runs through. So
adjusting the particle size or the stiffness might help.

Any idea about the viscous damping with clumps? Is there some
theoretical relation ship?

Thanks
