Air diffusion in room
 

Hi everybody,
I have an issue in a simulation of air conditioning diffusion system. Let me describe it:
I have a room where there is an air diffuser (inlet) in the ceiling and in the floor an air intake grill (outlet).
The temperatures of the walls are fixed (27°C) as well as the temperature of the air inlet (45°C).
I want to simulate the diffusion of the arie into the room.
I’m going to use the solver BuoyantBoussinesqsimplefoam.
The simulation doesn’t converge as I have done.
I have the following questions for you:
1) The used solver is correct?
2) Which boundary conditions for pressure, temperature and velocity are preferred to use for this application both for inlet or outlet and for the wall?

Hi, have you resolved?
