How many geometry domains?
I'm wondering what is good practice for relatively complex geometries. If the direction and velocity of flow is very different throughout the geometry, should I split it into a bunch of domains with interfaces so that I can set their initializations seperately? Or should I be keeping it as simple as possible?
Particularly with slow multiphase flows, CFX seemed to have a lot of difficulty producing convincing results if I didn't split it up and set initializations for velocity, direction, and mass or volume fraction seperately.
