I ran the tutorial simulation and it helped a lot. What I still do not understand is that while there is only one solid (which is the flow region), but there are still other entities in the model that you can select and change their attributes. They are placed under the topological entity sets. How do i differentiate these from the flow region? If I just import the negative Boolean model I will not be able to select where the inlets, outlets, and occupants are. Do this question make sense?
