Question #238759 on Yade changed:
https://answers.launchpad.net/yade/+question/238759

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hi Ricardo,

what spahe do you use for plates? Walls, facets, ...?

what material do you use for the plates? again CpmMat? if so and you use
Bo1_....aabbEnlargeFactor and Ig2_....interactionDetectionFactor, than some
cohesive bonds are created between spheres and plates. The possible
solutions are:
1) delete "manually" the interactions created between plate and spheres
after first step
2) use different material (FrictMat) for plates
and Ip2_FrictMat_CpmMat_FrictPhys in Ip functors in addition

cheers
Jan
