Question #696759 on Yade changed:

Status: Open => Answered
Jan Stránský proposed the following answer:
One approach is this:
- add "basic" Frict... stuff to InteractionLoop
- create the packing, spheres/polyhedrons with CpmMat, walls with FrictMat, set
interactionDetectionFactor, aabbEnlargeFactor etc.
- run one iteration to create cohesive bonds
- reset interactionDetectionFactor, aabbEnlargeFactor..
- set material to all particles to FrictMat
This way, cohesive bonds would remain cohesive Cpm interactions (modifying
particle material ha no effect on existing interactions) and new contacts would
be of FrcitMat type.
This IMO makes physical sense, Cpm gives no extra features for non-cohesive
interactions plus you can independently set friction angle, which has different
meaning for cohesive and non-cohesive interactions in Cpm.
Cheers
Jan
