Luc Scholtès proposed the following answer:
Hi,

I am not sure to understand your request ("contact forces changing
colors on particles"?) but it is possible to see the principal stresses
applying on each particle by adding the 'bstresses' attribute in the
VTKRecorder (along with the 'spheres' attribute of course). Then, you
can select the stress you are interested in and color the glyph
associated to each point (e.g. a sphere) according to the stress
magnitude. If you want to see the interaction network, it is also
possible by adding the 'intr' attribute in the VTKRecorder. Then, by
selecting the component of the forces you want to see (normal or shear)
and coloring it according to their intensity you can see how the forces
are distributed in your assembly.

I don't know if these options work for polyhedron though.

Luc
