What boundary conditions i have to use for a natural convection with heating ? I used Pinlet = 0 and Poulet = 0. Is it fine ?

Thank you .

Two fixed-pressure inlets, both set at P=0, will be OK. Because of the weak body force you are likely to get, you need to set your under-relaxations carefully to ensure good convergence.
