Difficulty setting up an enclosed room fan simlation


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!


Hi there!

Your project is not found, is that the right link? Also tagging the @CFD-SQUAD here also make sure to use the search function as this issue has been encountered by other people several times (multi-region mesh). One thread that can help is that one: A multi-region mesh was assigned - this analysis-type requires a single-region mesh
