In my opinion, these geometry details must be very tiny. In most cases, the practical effect of the doubled reaction will negligibly small. But I run additional test with tiny mesh then the size of facets considerably less sphere's size and got the same result. I have updated figs on wiki: http://images3.wikia.nocookie.net/yade/images//0/00/Rod-total-force.png http://images2.wikia.nocookie.net/yade/images//e/e6/Rod-tiny.jpg > > http://images4.wikia.nocookie.net/yade/images//6/68/Rod-coarse.jpeg > > http://images1.wikia.nocookie.net/yade/images//6/69/Rod-fine.jpeg > I would suggest >adding some possiblit (flag?) to turn on/off reactions on each >particular edge and vertes - this way, there could an algorithm that >would enable only one of the coinciding edges etc. Does that make sense? I think about it. This will be a half solution. See fig: O O | /| ====*------- where === is a one facet, ---- is a other facet, * is a edge, O is a particle, | is a contact. If contact with edge will be enabled only with === facet, then this contact will be enabled _and_ with contact with --- facet, but in this case, contact with the edge will be mistake. -- Best regards, Sergei D. _______________________________________________ Mailing list: https://launchpad.net/~yade-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-dev More help : https://help.launchpad.net/ListHelp
