'Pressure' in CFX-Post

Atit Koonsrisuk

I read from one topic, Robin said that 'Pressure is the relative static pressure (relative to the reference pressure you input in the Domains form). If you are running 5.5.1, the hydrostatic pressure contribution will also be included.' I use CFX 5.5.1 to compute the problem with one inlet and one outlet. It is the problem about natural convection with significant hydrostatic pressure. I specify 'Openning' with zero total pressre at inlet, and 'Outlet' with zero average static pressure at outlet. I got the reasonable results. I have to add the hydrostatic pressure to 'pressure' in CFX-Post, then I get the value of pressure almost the same as the value from my own Fortran program. What is the problem of mine? Thank you very much.
