Hi! I am working on simulating heat flow in a warming cabinet. I am quite new to this but I’m struggling with defining boundaries in this closed system.
As you can see in the picture id like there to be a velocity inlet into the cabinet (basically an oven) at a speed of 0.975m/s (red arrows) and a pressure outlet past the flaps on the back panel (blue arrow). The fan region will be a rotating zone at rpm 220. Element is a 500W power source. Any idea how I can define the boundaries without there being an error - Multiple boundary conditions or interface assignments for the following entities: face1821@air, face1804@air, face1778@air
Any other tips to improve my simulation is welcome:)
