Question #693672 on Yade changed: https://answers.launchpad.net/yade/+question/693672
Status: Open => Answered Jan Stránský proposed the following answer: > I am wondering if it covers all the interactions? yes, only the type of material is important, from the point of view of engines it does not matter that there are more CohFrictMats > the mortar -cement contact (like E, sigmaT and so on) is taken the average? depends on the parameter [2]: - stiffness is taken harmonic mean - friction angle is taken minimum - sigmaT does not belong to CohFrict* > if I want to define the mortar -cement contact manually and arbitrarily, how may I do it? it depends on your simulation (what is the packing, please provide a MWE [1]) and definition of "manually and arbitrarily". You can use createInteraction [3]. Or you can adjust parameters of existing interactions (unset cohesion, change material properties, ...) cheers Jan [2] https://gitlab.com/yade-dev/trunk/-/blob/master/pkg/dem/CohesiveFrictionalContactLaw.cpp#L314 [3] https://yade-dem.org/doc/yade.utils.html#yade._utils.createInteraction -- You received this question notification because your team yade-users is an answer contact for Yade. _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
