gauge pressure

Hi,
I have a model with transport of species and an incompressible ideal gas flow (natural convection within a building) with different boundary conditions which are: two pressure inlet and one velocity inlet. My question is if I specify the operating pressure = 101325 and gauge pressure = 0 in one pressure inlet, then, in the other BC with pressure inlet, which is 10 meters lower than this (in z axis), will FLUENT calculate the new pressure in this BC (according to P=rho*g*h)??
cheers

It will, if you had turned on gravity in the 'Operating Conditions'.
