I'm doing mold flow analysis, but this air vent parameter mesh selection seems very cumbersome. The part fills from the bottom. The top is vented from core pins. I've started selecting the mesh top faces nearest to the core pin, but I have ALOT of these to do and even a single segment takes a long time. Should I be selecting the top or the inner faces? Is there a better way to select the faces other than a selection rectangle or face by face?
