ConstitutiveLawDispatcher invokes go(IG&,IP&) of individual ConstitutiveLaw's (note that ConstitutiveLawDispatcher might be hidden inside InteractionDispatchers, but functionally it is the same) InteractionSolver was just empty class to designate such classes that were looping over all interactions. This approach was removed, since it forced all interactions to have same types. > Q2. When do I use CreateIndex()? It is different from > RegisterAttributes() right? createIndex(): Just for types that appear in the dispatch logic, currently: BoundingVolume, Material, InteractingGeometry, InteractionGeometry, InteractionPhysics. The dispatcher uses the indices to decide which functor should be called. Depending on whether it decides based on 1 type or combination of 2 types, it is then Dispatcher1D or Dispatcher2D (and Functor1D/Functor2D). Each functor declares what types it accepts with FUNCTOR1D(type1) or FUNCTOR2D(type1,type2) macro. It is like virtual functions, but works for combination of types and can be changed at runtime: you can have multiple Ip2_* functors in yade that take GranularMat for instance, but only the one the dispatcher is given by the user will be used. You can see that nicely in all the python scripts. REGISTER_ATTRIBUTES declares which attributes are saved to xml and also which are accessible from python with the ['attr'] notation (it is a rather convoluted macro) > Sometimes, I just copy-paste and modify but don't really understand > what's going on.. Try to do your best to understand. Of course it is a gradual process, but it will make your code much better.
