Hello folks, I designed and simulated a forced convection oven to study airflow into the oven cavity but I noticed that air does not flow into the cavity through the air gap I designed on the cavity. but flow around the cavity and avoid those gaps. I have no idea why. In my geometry, the cavity is inside an enclosure (fluid domain) with a fan with which the fan has its own casing. The enclosure has an inlet close to the fan and an outlet on top. I did 3 Boolean substractions- the enclosure and the fan case, the enclosure and the oven cavity, the fan case and the fan For meshing: I performed a body sizing on the fan case and also on the enclosure For the setup: it's a steady-state, I inputted necessary parameter for the fan case at frame motion under cell zone. For the bc, the inlet and outlet are pressure inlet and pressure outlet respectively and a no-slip wall for the external wall of the fluid domain. And also used hybrid initialization. Below is the geometry
