so it is good that I have asked :) Thanks for the pointers, after I read that I will have more questions. I want to go in this direction, instead of doing minkowski sum. I wonder how we could later merge that with your whole triaxial test. A reminder - my goal here is to obtain an inclined localization due to shearing. -- Janek Kozicki http://janek.kozicki.pl/ | _______________________________________________ Mailing list: https://launchpad.net/~yade-dev Post to : yade-dev@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-dev More help : https://help.launchpad.net/ListHelp
