Hi
i am working on natural convection simulation using MRF and Air domain ( acting as room ), basically the geometry is inside the Air domain and applied constant heat loss to the geometry. I ran 2 cases, one by applying pressure outlet at the boundary of the sphere and another case by applying wall at fixed temperature.

one with the pressure outlet removes lot of heat from the geometry and in case with wall does not.

which is the right one ?
