Hello Xavier,

Really ? I have had so many troubles with the CohFrictMat, I prefer the
JCFPMmat, I find it a lot more stable. What kind of simulation have you
implemented ?

I think, but I'm not an expert here, that those parameter are related to
bending and twisting moments, I guess they depend on the type of
material you are using, and how you would like to describe interactions
of particles with one another. So I think it also depends on the scale
of your particles.

So, a clump is unbreakable, so I would say it is not the best to model
crushing or breakage^^ You could however use clumps to model irregularly
shaped particles. I think I saw another thread on the launchpad of a guy
modelling crushing of particles with agglomerates, can't find it right
now, but you should try and have  look in the topics !
