Good Morning

I am a master student that is studying the stator-rotor interaction in an hp turbine stage (22 stat X 25 rot blades).
I already set up the phase lag time integration unsteady solution and now I'd like to see the Harmonic Balance in term of performance and computational time.
I read the Help of CFX but it tells only how to set up the blade flutter case.
Does anyone have any suggestion on how to set up the Harmonic Balance method for un unsteady stage simulation?
P.S. I just want to simulate the fluid mechanics, I have no interest in mechanical response of the blades.

Thanks in advance.

The only supported (documented) use case for Harmonic Balance is the Blade Flutter case.

You must wait until the stator-rotor use case is released.

hi...., brambilla, I'm naveen, pursuing my master thesis, can you kindly share the harmonic balance cfx setup file, it will be very helpful for my thesis. my email: naveen.13red@gmail.com

Thanks in advance
