Question #622060 on Yade changed: https://answers.launchpad.net/yade/+question/622060
Description changed to: I am trying to run a packing model,and try to use TesselationWrapper() to obtain the strain-changing-field. I write the script following the example: tesselationWrapper.py . My specific script is like tihs: ----------------------------------------------------------------------------------------------------------------- O.reset() O.bodies.append(geom.facetBox((.5,.5,.5),(.5,.5,.5),wallMask=63)) from yade import pack sp=pack.SpherePack() sp.makeCloud((0,0,0),(1,1,1),rMean=0.02, rRelFuzz=0.1) sp.toSimulation() O.engines=[ ForceResetter(), InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Facet_Aabb()]), InteractionLoop( [Ig2_Sphere_Sphere_L3Geom(),Ig2_Facet_Sphere_L3Geom()], [Ip2_FrictMat_FrictMat_FrictPhys()], [Law2_L3Geom_FrictPhys_ElPerfPl()] ), NewtonIntegrator(gravity=(0,0,-9.81),damping=0.4), ] O.dt=0.05*PWaveTimeStep() O.run(5) TW=TesselationWrapper() TW.triangulate() TW.computeVolumes() TW.volume(20) TW.setState(0) O.run(10,True) TW.setState(1) TW.defToVtk("strain.vtk") ----------------------------------------------------------------------------------------------------------------------------------------- when I run the script, the result is: ----------------------------------------------------------------------------------------------------------------------------------------- Triangulated Grains : 7432 sym_grad_u_total_g (wrong averaged strain): 0 0 -1.0106e-17 0 0 -1.0839e-17 -1.0106e-17 -1.0839e-17 -7.99784e-17 Total volume = 0.87657, grad_u = 0 0 0 0 0 0 -2.0212e-17 -2.16781e-17 -7.99784e-17 sym_grad_u (true average strain): 0 0 -1.0106e-17 0 0 -1.0839e-17 -1.0106e-17 -1.0839e-17 -7.99784e-17 Macro strain : 0 0 0 0 0 0 0 0 0 Cannot open file [strain.vtk] ----------------------------------------------------------------------------------------------------------------------------------------- Can someone help me? For I am new to YADE,I cannot understand the meaning of the result.
