Help with Inertial Filter simulation


I’m trying to simulate an inertial filter, wich will work at 0.95 m3/h, and I need to know how much pressure drop will it generate. The error I’m getting is “A multi-region mesh was assigned - this analysis-type requires a single-region mesh”. The air should enter by the bottom face and exit at the top face.
Can someoner help me?


Hi @Zarcian: You need to edit your geometry. It is ‘Internal CFD’ hence please create one solid (enclosure) and remove with Boolean operation all ‘Deflectors’. You can study the example of Internal CFD here:, it does contain MRF zone which you will not have.
