Vaclav not exactly. lattice works with compression, but has one limitation I never came around to fix - it doesn't have collision detection with itself. Once something breaks into two halves, they can overlap if they move onto each other. But I didn't need to fix this for my calculations, because the deformations were so small, that if something breaks - it doesn't move more than the crack size. concrete is a fake rock, lattice will work for rock fracturing, subject to collisions limitation. Adding collisions is possible by enveloping a lattice mesh into a polyhedron and use collision detection between polyhedrons. A bit of work, though. Lattice can not do dynamics, though. No impacts, etc. Only quasi-static simulations. -- Janek Kozicki | _______________________________________________ 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
