Complex stuff! Are you just trying to make the code foolproof or is there another reason?Fixing the state type is perhaps not necessary : it would make something not desired by the user anyway, for good or bad. Wouldn't displaying "you picked a wrong mat/state combination" be enough?
In that case, it could be tested only once, e.g. in the constitutive law or IPdispatcher at first iteration, using Material::checkStateType(Body* b). Not very elegant though, since this is a loop on interactions instead of bodies...
Another possible location for this would be in body->assignMatType(MatType* t), which could call t->checkStateType(this). The problem is it requires that the state type is always defined before the mat type...
So, initializers perhaps? Bruno
Material CpmMat requires that the body has CpmState (deriving from State), e.g. to record per-body damaged contacts etc. I can imagine some other materials might have similar requirements. What would be a clean way to assure that?Obviously checking that in the constitutive law at every step might betime-consuming. My idea was to declare virtual void Material::fixStateType(Body* b), which would check type of b->state and fix it if necessary (e.g. using copy constructor of a class derived from State and re-assign b->state to the new instance). But where to run that? Add it automatically to initializers? In the end, the user will have to be aware of this, at least on the c++ side. In python, we can ensure the right type in utils.{sphere,facet,wall} easily. Any ideas on it? _______________________________________________ Mailing list: https://launchpad.net/~yade-dev Post to : yade-dev@xxxxxxxxxxxxxxxxxxx Unsubscribe : https://launchpad.net/~yade-dev More help : https://help.launchpad.net/ListHelp
