Hi all, I am trying to simulate the air movement in a room given fan elements placed in several locations. I’m not interested in physically modeling the fan elements themselves, I just need to represent them with boundary conditions representing their flow rates. What I have tried to do is represent them as cylinders with one face defined as a pressure inlet, and the other defined as either a velocity outlet or a mass flow outlet. The simulation is not meshing with this technique, and I get the following error: A multi-region mesh is being used in a single-region analysis type. Please make sure that all regions except for one have an advanced concept assigned to them.
Any help appreciated!
