implementing reduced pressure in the modeling of the natural heating/non-isothermal flow

Dear All,

does anyone know how to implement something similar to " reduced pressure option available in comsol 5.2a or later" in older versions in the modeling of a non-isothermal flow with natural convection?

I am modeling a laminar flow with heat transfer and when I apply the gravity as a volume force, the pressure profile and velocity field get wrong compared to the situations without gravity force. it seems that the solver does not pay attention to my assigned outlet pressures in the boundary.I believe that I need to correct the pressure not to consider the hydrostatic pressure but I dont know how to do that in the version 5.2 of comsol.

thanks in advance, Jahanmir
