The InteractionPhysicsFunctors (like Ip2_CpmMat_CpmMat_CpmPhys, or, not yet named properly, SimpleELasticRelationships) compute parameters of the InteractionPhysics (e.g. kn, ks and all others) from 2 Material instances they receive. SimpleElasticRelationships receives 2xGranularMat and constructs an ElasticContactInteraction instance, with rigidities computed using some weird formulas. Ip2_CpmMat_CpmMat_CpmPhys receives 2 CpmMat instances, creates a CpmPhys, but most of its values are assigned from values of the functor itself.

LawDispatcher dispatches based on InteractionGeometry and InteractionPhysics types. If this combination is different, you can handle by a different constitutive law as well. We might add some more flexibility here, if it is desired. Have a look at http://beta.arcig.cz/~eudoxos/yade/sphinx/ ; although in nascent state, you might gather some useful information from there. v _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
