Question #706218 on Yade changed: https://answers.launchpad.net/yade/+question/706218
Status: Open => Answered Jan Stránský proposed the following answer: > And, do you imply that the strain analyses for clumps themselves is not possible for clumps yet? I have no idea (I do not use this stuff almost at all). The approach below should work, you can experiment with other approaches. > By mirroring do you mean releasing from clumps No. By mirroring I mean just create separate simulation where for the strain analysis purposes, clumps are replaced ("mirrored") by spheres with same state.pos and state.ori as the original clumps. Below is a MWE. Be careful with the scene switching, always "return" back where you want to continue. I am not sure if sphere sizes should be adjusted or not.. ###### def mirror(): # extract state from cumps states = [(b.state.pos,b.state.ori) for b in clumps] # switch to "spherical" simulation O.switchScene() # set states to the spheres for (pos,ori),b in zip(states,O.bodies): b.state.pos = pos b.state.ori = ori # create dummy clump packing for x in (0,1): for y in (0,1): for z in (0,1): clumpId,ids = O.bodies.appendClumped([ sphere((x,y,z),0.1), sphere((x+0.2,y,z),0.1), ]) clumps = [b for b in O.bodies if b.isClump] # create spheres in separate simulation (same amount as the clumps) O.switchScene() O.bodies.append([sphere((0,0,0),0.1) for _ in clumps]) O.switchScene() mirror() # note: simulation is switched TW=TesselationWrapper() TW.triangulate() TW.computeVolumes() TW.setState(0) O.switchScene() # switch back to "clump" simulation # some artificial motion O.bodies[clumpId].state.vel = (1,1,1) O.step() mirror() # note: simulation is switched TW.setState(1) TW.defToVtk("strain.vtk") O.switchScene() # switch back to "clump" simulation ###### Cheers 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
