natural convection in a heated box
Hi, i have to solve a natural convection problem in a box with an inlet and outlet and a heated floor. but it seems if i just model the box, the inlet doesnt work. it seems that the air does not come in, and the problem is i dont know the value of the incoming air, it should take so much air like the heated floor needs. Does anyone know which specific boundary conditions i set best to the inlet (pressure inlet, velocity inlet etc) and outlet? or do i have to model a big box around the heated small box? i hope anyone can help me.
