Mahdeyeh is still having a problem:
I really appreciate your patience Jan.

I corrected the codes in question and two polyhedrons have interact
(With using your suggestion for young modules (Dolomite.young = 5e7
Bound.young = 1e300) and O.dt=10e-6). But when there are more polygons,
problem appears.

> You can decrease stiffness of polyhedrons and increase stiffness of
facets artificially (e.g. 1e300, the harmonic average in contact law
makes it ok)

You know, this works for two polyhedrons! When I checked with more
polyhedrons, the problem was still there.

> what about 1e-10? 1e-12? 1e-15? 1e-20?
In fact, I have no idea because if problem is really solved with these time steps, simulation will be impossible for me because my original code have 920 particles and it takes a long time.
