when i am using inlet velocity BC with very small value like 10^-6 m/s, then solution is converging but in case when i am using pressure inlet BC which is preferred fo NC bouyancy driven flow, solution is not converging even with constant T & q''. Mesh is very simple like a two vertical and parallel plates with one adiabatic wall and other heating.
