Question #690742 on Yade changed:
https://answers.launchpad.net/yade/+question/690742

    Status: Open => Answered

Jan Stránský proposed the following answer:
The idea is to let Yade connect automatically all "close" particles with cohesive bonds (using 'factor', aabbEnlargeFactor and interactionDetectionFactor).
It connects particles within a grain, which is OK.
But it also connect close particles form different grains. These interactions are deleted by O.interactions.erase

"the special property of CpmMat" is
Ip2_CpmMat_CpmMat_CpmPhys.cohesiveThresholdIter, which tells Yade to
consider new interactions ad s non-cohesive if O.iter > this value.

cheers
Jan
