Re: [Yade-users] [Question #242137]: Periodic boundaries on given surfaces of the cell
Question #242137 on Yade changed: https://answers.launchpad.net/yade/+question/242137 Bruno Chareyre proposed the following answer: Another curiosity question : may walls sometimes be periodic, or never ? If you meant Box instead of Wall, they can be periodic in theory, but practically it is not possible currently. The problems are we don't have Box-Box interactions and a poor handling of Box-Sphere in arbitrary cases. -- 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

Question #242137 on Yade changed: https://answers.launchpad.net/yade/+question/242137 Status: Answered = Open jduriez is still having a problem: Ok, I think oversizing the cell will be ok for me, thanks François ! On the other hand, I did not catch how the first trick you mentionned (with the non-diagonal terms) may help to not consider periodicity on some surfaces ? And if it may apply to a parallelepiped that is rectangular (I did not mention this) Another curiosity question : may walls sometimes be periodic, or never ? -- 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

Question #242137 on Yade changed: https://answers.launchpad.net/yade/+question/242137 Kneib François posted a new comment: Hi, I tought you needed a periodic box with a special shape, and that using walls was a workaroud to obtain that. But if you actually want to have 2 non periodic axes the solution you chose is the right one. Just to remind, the cell have to be oversized a little in the non-periodic directions, and the wall have to be oversize regarding the maximal sphere distance flown through the periodic direction. -- 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

Question #242137 on Yade changed: https://answers.launchpad.net/yade/+question/242137 Status: Open = Answered Kneib François proposed the following answer: Hi, It is possible to generate a parallelepipedic cell by introducing non- diagonal terms in O.cell.hSize : Example : O.cell.hSize=Matrix3(1.,1.,0.,1.,1.,1.,0.,1.,1.) If you don't want to do that, you can make a rectangular cell oversized in the non-periodic directions. Then add some very large walls or boxes to contain spheres for this two directions. The trick is to set the allowBiggerThanPeriod=1 flag into the collider : Example : InsertionSortCollider( [Bo1_Box_Aabb(), Bo1_Sphere_Aabb()], allowBiggerThanPeriod=True, verletDist=0.) So it's a weird concept : walls will be non-periodic but spheres will. That's the reason why you will need to oversize walls, if your spheres travel through N perdiod in the periodic direction, the walls size must be at least N*period_size.
