Question #677865 on Yade changed: https://answers.launchpad.net/yade/+question/677865
Status: Solved => Open dan.wang is still having a problem: hi Jan when I try your method, it seems that the displacement is applied on the top of the particles, but there is no interactions between particles, why this happens? the total code is: ### from yade import plot,qt from yade.pack import * from yade import pack, plot, ymport O.materials.append(CpmMat(damLaw=0,young=170e9,density=4800,frictionAngle=atan(0.8),poisson=0.4,sigmaT=20e8,epsCrackOnset=0.8e-4,relDuctility=300,label='cpm')) kw={'material':'cpm'} O.bodies.append(ymport.gengeoFile('geo_crack.geo',shift=Vector3(0.0,0.0,0.0),scale=1.0,**kw)) O.dt=1e-7 EnlargeFactor=1.0 O.engines=[ ForceResetter(), InsertionSortCollider([Bo1_Sphere_Aabb(aabbEnlargeFactor=EnlargeFactor,label='bo1s')]), InteractionLoop( [Ig2_Sphere_Sphere_ScGeom(interactionDetectionFactor=EnlargeFactor,label='ig2ss')], [Ip2_CpmMat_CpmMat_CpmPhys()],[Law2_ScGeom_CpmPhys_Cpm()]), NewtonIntegrator(), ] #only XY directions are needed for b in O.bodies: b.state.blockedDOFs='zXY' ### bottom = [b for b in O.bodies if b.state.pos[1] < 9.66] for b in bottom: b.state.blockedDOFs = 'xyzXYZ' top = [b for b in O.bodies if b.state.pos[1] > 140.6] for b in top: b.state.vel[1] = -1.0/ O.dt O.step() ##### the geo_crack.geo file is shown in the original questions.
