Question #293247 on Yade changed:
https://answers.launchpad.net/yade/+question/293247
Status: Open => Answered
Jan Stránský proposed the following answer:
Hi Jonathan,
currently you can have only one instance (thus one set of parameters) of
p2_FrictMat_FrictMat_MindlinPhys. If needed, it could be modified to
distinguish between sphere-sphere and sphere-box interactions, but it would
need some coding and probably would be a bit hacky..
Do you have more boxes in your simulation? If no, I would use box instead
of polyhedra.
cheers
