inlet mass flow rate BC
I'm simulating a 3d- compressor with constant mass flow rate - inlet boundary condition and constant static pressure - outlet boundary condition. When the solution have converged I find a positive static inlet pressure (on the inlet face). Normally it should be negative, as there is gas with atmospheric condition (== operating pressure) flowing through the inlet face. And the total inlet pressure should be zero (compensated with the positive dynamic pressure) Can somebody explain me where I make (or Fluent???!!!) a mistake?
