Question #266828 on Yade changed: https://answers.launchpad.net/yade/+question/266828
loiseaurare posted a new comment: Hi Jerome, I have been reading your comment on the introduction of an equilibrium distance using cohFrictMat. I am not sure I understood properly what you point out : my interrogation comes from reading this previous thread --> https://answers.launchpad.net/yade/+question/295035, where the problem of initial offset or undesired movements was not raised. I do not understand why there should be a problem in the first computational loop, is it not possible to loop over all interactions in order to set i.phys.unp = i.geom.penetrationDepht BEFORE entering the actual computation loop ? Or does Yade need to actually perform a first loop in order to set initial values of the simulation ? Plus, I was also reading the thread https://answers.launchpad.net/yade/+question/269724 discussing whether Yade would match the BPM model features, and you mentioned that in JCFpmMat, the initial distance between particles is automatically set as the equilibrium distance ? So there is no need to use the initD function in order to achieve a zero stress state for initial overlapping particles using that contact law ?
