Hi all! The flow is incompressible one, and I want to know how to define the flow as incompressible model in CFX5.5?

Hi Miko It is fairly simple. Use any constant density fluid. The simulation will be incompressible. For compressible flow you have to specify equation of state. For example for compressible flow you can use air ideal gas as fluid.

Hi zahid! Do you mean that I should set Fluid Type to General Fluid in Fluids Editor Form and put a specific value in the Density? And is that ok?

Hi Miko You can use any fluid of your interest. For example Water RT , air etc. The key point is that its density should be constant.
