[Yade-users] [Question #667812]: RotationEngine on a clump
New question #667812 on Yade: https://answers.launchpad.net/yade/+question/667812 Dear all, I have been struggling recently to apply the RotationEngine on a clump of spheres. My goal is basically to let the clump roll over the floor, as a wheel would do. The forward movement comes from the traction between the wheel and the floor, so the TranslationEngine is not used. My questions are: - what am I doing wrong? I tried several things: apply the rotation engine on the individual spheres or on the clump ID, rotate around the center of mass, ... - Is the same thing possible with a clump of facets? Here's an example: I'm using Yade 2018.02b-50-e0894fb~xenial (I want to work with cohesive materials, hence the cohesive physics. I guess this doesn't matter) ## MWE from yade import plot, utils, pack, geom, ymport, polyhedra_utils, timing ## MATERIALS CohFrictMat02=CohFrictMat(label='CohMat1',id=2, density=2.6e3,young=1e6,poisson=1e0,frictionAngle=numpy.pi/2*0.8, isCohesive=False) ## DEFINE BODIES # Fixed Reference sp=pack.regularOrtho(pack.inAlignedBox([-0.4,-0.4,-0.11],[0.4,2.0,0.1]), radius=0.1, gap=0.0, material = CohFrictMat02, fixed = True) O.bodies.append(sp) # Clump to be rotated sp=pack.regularHexa(pack.inAlignedBox([-0.3,-0.3,0.2],[0.3,0.3,0.8]), radius=0.1, gap=0.0, material = CohFrictMat02, wire = True, fixed = False, ) RotatingClumpID_L = O.bodies.appendClumped(sp) ## APPEND CLUMPED RotatingClumpID = RotatingClumpID_L[0] RotatingSpheresID = RotatingClumpID_L[1] # RotatingSpheresID = O.bodies.append(sp) ## APPEND NOT CLUMPED (for testing) ## dT dt=O.dt=polyhedra_utils.PWaveTimeStep() # ## MODEL Gravity = -9.8 # Gravity = 0.0 ## Engines O.timingEnabled=True EnlargeDetectionRadius = 1.1 RotEngine = RotationEngine(angularVelocity = -10.0, rotationAxis = (1,0,0), ids = [RotatingClumpID,], # ids = RotatingSpheresID, # ids = [RotatingClumpID,]+RotatingSpheresID, # ids = [RotatingSpheresID[0],], rotateAroundZero=1, zeroPoint=O.bodies[RotatingClumpID].state.pos, # rotateAroundZero=0, label = 'RotationTootToot',) O.engines=[ ForceResetter(), InsertionSortCollider([ Bo1_Sphere_Aabb(aabbEnlargeFactor = EnlargeDetectionRadius), ]), InteractionLoop( [ Ig2_Sphere_Sphere_ScGeom6D(interactionDetectionFactor = EnlargeDetectionRadius), ], [Ip2_CohFrictMat_CohFrictMat_CohFrictPhys()], [Law2_ScGeom6D_CohFrictPhys_CohesionMoment(always_use_moment_law = False, creep_viscosity = 1, shear_creep = False, twist_creep = False, )], ), NewtonIntegrator(gravity=(0,0,Gravity),damping=0.8), # Gravity RotEngine, PyRunner(iterPeriod=1,command="RotEngine.zeroPoint=O.bodies[RotatingClumpID].state.pos"), ] Thanks 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

[Yade-users] [Question #670376]: frictAngle matchmaker in Ip2_CohFrictMat_CohFrictMat_CohFrictPhys
New question #670376 on Yade: https://answers.launchpad.net/yade/+question/670376 Dear all, I'd like to use a matchmaker to specify the friction angle between different material types. The simulation uses cohesive materials, so I'm using Ip2_CohFrictMat_CohFrictMat_CohFrictPhys. However, it seems this functor doesn't accept a frictionangle matchmaker: frictAngleMatchMaker = MatchMaker(algo='max') Ip2_FrictMat_FrictMat_FrictPhys(frictAngle = frictAngleMatchMaker) Ip2_CohFrictMat_CohFrictMat_CohFrictPhys(frictAngle = frictAngleMatchMaker) returns: File "/../FrictAngleMatchmaker.py", line 3, in Ip2_CohFrictMat_CohFrictMat_CohFrictPhys(frictAngle = frictAngleMatchMaker) AttributeError: No such attribute: frictAngle. I was thinking this would be possible, since it's based on Ip2_FrictMat_FrictMat_FrictPhys. Is there a way to get around this? -- 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
