According to the method of Euler equation for turbomachinery, I have designed the rotor geometry (Hub / shroud / blades) which operates according to the characteristic curve of operation.

Now, in CFX, I have set the mass flow as a boundary condition at the fan inlet, and I want the simulation determines the pressure variation for a given flow rate mass and set rotor rotation!
So i cannot impose any pressure on the boundary condition at the OUTLET of the fan.
What should i choose?
It is correct if I choose again the mass flow as a boundary condition at the outlet? I want to determine the characteristic curve.

thanks

You will need to read CFX manual for BC settings before asking here.
