New question #586294 on Yade: https://answers.launchpad.net/yade/+question/586294
Hello all, I am using Yade for my research on the statistics of soil behavior at various scales. One thing that I have been wracking my brain on, is how to impose a uniform traction boundary on a confined polydisperse model. TriaxialStressController works wonderfully for a uniform-displacement boundary, but I don't see a way to use for uniform-traction. Perhaps someone has already worked on this or at least given it some thought? Maybe this ability is already built in and I am just not seeing it? The only reference I can find in the literature is this paper https://arxiv.org/pdf/1612.07006.pdf. One idea I had on how to do this with Yade is to turn off TriaxialStressController after confinement, then get a list of the boundary particles using O.interactions.withBody(w) where 'w' is a body representing a wall. Once I have a list of the boundary particles, I can use O.ForceContainer.setPermF() to apply to each particle a force proportional to its cross-sectional area. That should work in principle, although I suppose I would have to introduce some dynamic relaxation to the boundary particles. Thank you for any thoughts/suggestions. -- 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
