New question #293471 on Yade: https://answers.launchpad.net/yade/+question/293471
In the name of god Hello all I want to simulate a gravity deposition. The particles are generated in a circular predicate. If FrictMat is used, there is no problem and the particles flow freely on the horizontal wall; But in the case of CpmMat, it seems that the bonds between particles is made. With regarding to this point that i have setted intRadius = 1 and there is no initial overlap, why bonds between particles are made? ######## from yade import pack mat=CpmMat(young=1e9,neverDamage=True,epsCrackOnset=1e-2) O.materials.append(mat) ###generating circular predicate and filling with spheres pred=pack.inCylinder(centerBottom=(0.5,0.5,0),centerTop=(0.5,0.5,1),radius=.25) spheres=pack.randomDensePack(pred,spheresInCell=500,radius=.55e-1) O.bodies.append(spheres) O.bodies.append(wall(-0.1,axis=2)) intRadius = 1 O.engines = [ ForceResetter(), InsertionSortCollider([Bo1_Sphere_Aabb(aabbEnlargeFactor=intRadius,label='is2aabb'),Bo1_Wall_Aabb()]), InteractionLoop( [Ig2_Sphere_Sphere_ScGeom(interactionDetectionFactor=intRadius,label='ss2d3dg'),Ig2_Wall_Sphere_ScGeom()], [Ip2_CpmMat_CpmMat_CpmPhys()], [Law2_ScGeom_CpmPhys_Cpm()] ), NewtonIntegrator(gravity=(0,0,-10),damping=0.5) ] O.dt = 0 O.step() is2aabb.aabbEnlargeFactor = 1. ss2d3dg.interactionDetectionFactor = 1.
