[Yade-users] Removing contact laws
Hi all, I'd like to remove some of the contact laws which are in Yade. Some of them are unmaintained and/or broken and/or duplicates, and too many contact laws is only making the choice uneasy.

Question #199540 on Yade changed: https://answers.launchpad.net/yade/+question/199540 Status: Open = Answered Chiara Modenese proposed the following answer: Hi Bruno, If I am not wrong: Law2_SCG_MomentPhys_CohesionlessMomentRotation is a duplicate of Law2_ScGeom6D_CohFrictPhys_CohesionMoment (but with less features than the latter) Law2_SCG_MomentPhys_CohesionlessMomentRotation is the only Law that implements the rolling resistance using quaternions (actually there is something similar about twist_creep in Law2_ScGeom6D_CohFrictPhys_CohesionMoment) which I would not recommend as I am not sure it always gives the expected result (has anybody tested it properly?) In principle the rolling resistance implemented in Law2_SCG_MomentPhys_CohesionlessMomentRotation does not seem to be doing anything different than what is already implemented in Law2_ScGeom6D_CohFrictPhys_CohesionMoment which, however, uses an incremental fashion (a copy of what I introduced in the Law2_ScGeom_MindlinPhys_Mindlin Law) that seems to work fine from what I gathered Why do you say it implements irreversible rolling friction? Finally, I would remove it if nobody is using it. Thanks!
