Dear, I need some help!

I am doing a simulation of a rotor and diffuser and would like to do the analysis of vibration of the passage of the blades (rotor 6 blades and diffuser 8 blades), does anyone have a similar tutorial?

To capture pressure fluctuation I imagine it to be a transient analysis with the initial condition of a stationary simulation with the same boundary conditions (I do not know if I'm correct!) .

But how do I determine the frequency of vibration? Is it in the CFX module?

Sorry if I'm writing nonsense, but the lower is the value of the pressure fluctuation between blades becoming favorable?

I thought about simulating 1/100 of the time of each passage.

Thank you

Have a look at the blade flutter tutorials on the ANSYS Customer website. If this model is relevant to you it will assist greatly.
