Hello,

I am working on steady state simualtion of centrifugal compressor and I want to evaluate pressure ratio in CFD post. When I go to function calculator, I see average and massflowaverage values of pressure. Which one is right in this case? I checked one thread for transient simulation and he used massflowaverage of total pressure at inlet and oulet. However when I do this I get very high pressure ratio. When I use simple average of total pressure at inlet and outlet, I get more reasonable value of slightly greater than 3. which one is right?

One more question is I have a converged solution for one mass flow rate, how can i use this one for other mass flow rates so that simulation converges faster?

Thank you.
