New question #676232 on Yade: https://answers.launchpad.net/yade/+question/676232
Hello, I was able to run the example for FEM&DEM but suddenly I am having problem running prepareRVE.py code. It is giving error below. s@s-VirtualBox:~/Desktop/TEST16NOV$ python prepareRVE.py Traceback (most recent call last): File "prepareRVE.py", line 3, in <module> O.materials.append(FrictMat(young=6.e8,poisson=.8,frictionAngle=.0)) NameError: name 'FrictMat' is not defined I wonder why, please find below the complete script. I was able to run the same python few months back.. from yade import pack O.materials.append(FrictMat(young=6.e8,poisson=.8,frictionAngle=.0)) sp = pack.SpherePack() size = .24 sp.makeCloud(minCorner=(0,0,.05),maxCorner=(size,size,.05),rMean=.005,rRelFuzz=.4,num=400,periodic=True,seed=1) sp.toSimulation() O.cell.hSize = Matrix3(size,0,0, 0,size,0, 0,0,.1) print len(O.bodies) for p in O.bodies: p.state.blockedDOFs = 'zXY' p.state.mass = 2650 * 0.1 * pi * p.shape.radius**2 # 0.1 = thickness of cylindrical particle inertia = 0.5 * p.state.mass * p.shape.radius**2 p.state.inertia = (.5*inertia,.5*inertia,inertia) O.dt = utils.PWaveTimeStep() print O.dt O.engines = [ ForceResetter(), InsertionSortCollider([Bo1_Sphere_Aabb()]), InteractionLoop( [Ig2_Sphere_Sphere_ScGeom()], [Ip2_FrictMat_FrictMat_FrictPhys()], [Law2_ScGeom_FrictPhys_CundallStrack()] ), PeriTriaxController( dynCell=True, goal=(-1.e5,-1.e5,0), stressMask=3, relStressTol=.001, maxUnbalanced=.001, maxStrainRate=(.5,.5,.0), doneHook='term()', label='biax' ), NewtonIntegrator(damping=.1) ] def term(): O.engines = O.engines[:3]+O.engines[4:] print getStress() print O.cell.hSize setContactFriction(0.5) O.cell.trsf=Matrix3.Identity O.cell.velGrad=Matrix3.Zero for p in O.bodies: p.state.vel = Vector3.Zero p.state.angVel = Vector3.Zero p.state.refPos = p.state.pos p.state.refOri = p.state.ori O.save('0.yade.gz') O.pause() O.run();O.wait() Thanks and best regards Surej. -- 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
