Question #683706 on Yade changed: https://answers.launchpad.net/yade/+question/683706 Jingchi Yu posted a new comment: Hi， Jan and Leonard, I just see your discussion about the matchmaker, I am wondering that if I want to make cement-cement interaction is CohFrictPhys, sand-sand and sand-cement are all CohFrictPhys, whether it is ok to use the matchmaker? If it cannot work, how I can define the cohesive bond between the two materials?

Question #683706 on Yade changed: https://answers.launchpad.net/yade/+question/683706 Status: Open => Answered Jan Stránský proposed the following answer: Hi, > what kind of contact law yade uses for dealing with sand-cement interaction? Ip2_FrictMat_FrictMat_FrictPhys Because CohFrictMat is derived from FrictMat and if CohFrictMat-FrictMat Ip2 is not found, Yade tries it with base classes (FrictMat-FrictMat in this case). You can try on a simple 3 sphere example: ### sand = FrictMat(label='sand') cement = CohFrictMat(label='cement') O.materials.append(sand) O.materials.append(cement) O.engines=[ ForceResetter(), InsertionSortCollider([Bo1_Sphere_Aabb()]), InteractionLoop( [ Ig2_Sphere_Sphere_ScGeom(), Ig2_Sphere_Sphere_ScGeom6D() ], [ Ip2_FrictMat_FrictMat_FrictPhys(), Ip2_CohFrictMat_CohFrictMat_CohFrictPhys(setCohesionNow = True,setCohesionOnNewContacts = True) ], [ Law2_ScGeom_FrictPhys_CundallStrack(), Law2_ScGeom6D_CohFrictPhys_CohesionMoment() ], ), NewtonIntegrator(damping=0.4), ] s1 = sphere((0.0,0,0),1,material=sand) s2 = sphere((0.1,0,0),1,material=sand) c1 = sphere((0.2,0,0),1,material=cement) c2 = sphere((0.3,0,0),1,material=cement) O.bodies.append((s1,s2,c1,c2)) O.step() for intr in O.interactions: i1,i2 = intr.id1,intr.id2 b1,b2 = [O.bodies[i] for i in (i1,i2)] m1,m2 = [b.mat.label for b in (b1,b2)] print(m1,m2,intr.phys) ### cheers Jan -- 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
