Felipe Matos is on a distinguished road

I'm trying to simulate a incompressible steady-state flow inside a cilindrical tube. My regime is laminar, with no heat transfer. However, i'm not finding the compressibilty control, that is normally at Solver Control > Advanced Tab inside the CFX-Pre. Anyone knows how can I force the flow to be incompressible in such situation?

If you have defined your material density to be a constant the model will be incompressible. Alternately if you turn the heat equation off like you did that will also force it to do an incompressible simulation (unless you defined density as a function of pressure).
