Two forces pushing a particle from opposite sides will give zero in O.force (as they sum up as vectors); what you need (if you want mean stress) is to count compressive forces as positive and tensile as negative. And that depends on interaction orientation, see the bug I references. _______________________________________________ Mailing list: https://launchpad.net/~yade-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-dev More help : https://help.launchpad.net/ListHelp
