Jan Stránský proposed the following answer: Hi Mohsen, > >Not to create any cohesive interactions, use value less than 1 for > intRadius. > I formerly have check it; i reduced the value of intRadius to 0.1, but > again there were cohesive bonds between particles and the particles did not > FLOW freely. > if you reset the value to 1 after first step, the cohesive interactions are still created until 10th step, which is the default value for cohesiveThresholdIter, see below. > >Furthermore, check [1] and make it something like 1 in Ip2. > Jan there is something confusing! when is changed my code to use > 'cohesiveThresholdIter' i received an strange error: > ... > [Ip2_CpmMat_CpmMat_CpmPhys(cohesiveThresholdIter(-1))], > NameError: name 'cohesiveThresholdIter' is not defined > the correct syntax is Ip2_CpmMat_CpmMat_CpmPhys(cohesiveThresholdIter=1) Yade [9]: O.engines[2].physDispatcher.functors[0] > -> [9]: <Ip2_FrictMat_FrictMat_FrictPhys instance at 0x27fdc50> > _________ > although my material is Cpm, Yade [9] tells my functor is FrictMat!!!! this is probably because of the error during O.engines=..., after that the new values are not set and the default values remain (Ip2_FrictMat_FrictMat_FrictPhys among them). to conlude, after setting intRadius=0.5 and Ip2_CpmMat_CpmMat_CpmPhys(cohesiveThresholdIter=1), everything should work :-) cheers Jan PS: reading the answer once more, cohesiveThresholdIter=0 should work even with intRadius=1 -- You received this question notification because your team yade-users is an answer contact for Yade. _______________________________________________ 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
