Question #224128 on Yade changed: https://answers.launchpad.net/yade/+question/224128
Bruno Chareyre proposed the following answer: You can find examples of 2D simulations in examples/ring2d. As Jan explained, there is nothing special to do for building a 2D problem, except that you will align all spheres in one plane. Even blocking 'zXY' is not necessary in my experience. If all spheres are in one plane initially, they will sit there (all contact forces will be strictly 0 in z, hence there is no out-of-plane numerical error). For a 2D triaxial, it is enough to generate random positions using makeCloud with a flat box. Try this for instance: O.periodic=1 from yade import pack sp=pack.SpherePack() sp.makeCloud((0,0,0.5),(1,1,0.5),-1,.4,200,periodic=True) O.bodies.append([utils.sphere(s[0],s[1]) for s in sp]) or (if not periodic) O.periodic=0 from yade import pack sp=pack.SpherePack() sp.makeCloud((0,0,0.5),(1,1,0.5),-1,.4,200) O.bodies.append([utils.sphere(s[0],s[1]) for s in sp]) For the fun, you can also do this, but it is no longer 2D... O.periodic=0 from yade import pack sp=pack.SpherePack() sp.makeCloud((0,0,0.5),(1,1,0.5),-1,.4,200) sp.makeCloud((0,0.5,0),(0.8,0.5,0.7),-1,.4,200) O.bodies.append([utils.sphere(s[0],s[1]) for s in sp]) -- You received this question notification because you are a member of yade-users, which 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
