giacomo Guest Posts: n/a	Hi all, I have a question on defining rightly the pressure term for a pressure outlet boundary condition. I am modeling natural convection within an enclosure with free openings to the outside. When I am asked to enter the ambient ( = outside the domain) pressure should I enter the hydrostatic head ( = - (density * g * opening height)) or this is not required as it is computed automatically by the software. Any help will be appreciated, Thanks in advance, Giacomo
