He would have to implement box-box interactions; I think it is more work of thought (than knowledge of c++), as you have to handle vertex+facet edge+edge &c collisions; and there are also singular cases, therefore he may need to smooth the corners and edges... He might try to implement general convex polyhedra as minkowski sums instead (on which lots of articles was written), which would work for boxes as well, including rounded bricks. Third option is to complete the incomplete volumetric tetrahedra formulation, which I attempted 3 years back but never finished and create brick as clump of 3 tetrahedra. That said, IIRC some people (Bićanić?) were using DEM with implicit integration for brick structures, which apparently worked well. You can look at scholar.google.com. 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
