Contacts will be created when spheres get in touch automatically. However, for regular packing, some spheres may not touch (numerical rounding errors), so you should increase distance factor a little bit (1.05 or such) https://www.yade-dem.org/sphinx/yade.wrapper.html#yade.wrapper.Bo1_Sphere_Aabb.aabbEnlargeFactor Then you will have spheres bound in the packing firmly together. Constraints: depends on what you need. You can just block some DOFs on boundary spheres (https://www.yade-dem.org/sphinx/yade.wrapper.html#yade.wrapper.State.blockedDOFs) > I will read "CohesiveFrictionalPM" that Luc scholtes proposal, > what do you feel about it? Don't ask me what I feel about that code, the answer would not be politically correct (although I am not contesting its reported functionality). v _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
