Hi, everybody.
I'm working on simulation of cavitating flows around hydrofoils in cavitation tunnels. In order to match the experimental conditions, I want to specify static pressure at inlet of the computational domain(corresponding to inlet of the test section of the tunnel). However, by using the "pressure inlet" boundary condition in FLUENT, one can only fix the total pressure at the boundary, while the static pressure is allowed to float. Can you suggest a convenient solution to this problem? Thank you very much.

total pressure = dynamic pressure + static pressure.

dynamic pressure= 0.5 * density * (velocity^2).

So long as you don't have variable velocity or density at the inlet, those should work.
hope this helps.
