Question #177419 on Yade changed: https://answers.launchpad.net/yade/+question/177419
Status: Open => Answered Chareyre proposed the following answer: You're welcome. :) I believe our PBCs are mathematically equivalent to the ones found in FM (including the paper you mentionned) or in Radjai. They only differ in some implementation details (reduced coordinates in Radjai, shifted rectangles in the reference above, and probably many other variants). It is also possible probably to find examples of periodicity implementations not accounting for the macroscopic velGrad (especially in the field of quasistatic regimes where it doesn't really matter), since it is easier to implement. I don't see any of these implementations having specific problems with large strains as soon as the model is using a step-wise eulerian formulation. Large strain could only be a problem if the evolution at time t was a function of positions at time 0 (lagrangian formulation). I don't know any example of this kind in DEM-like methods. -- 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
