Hi All,

I am tring to find out the frequency in a shock wave using Power Spectral Density(PSD) in CFX. I have created the graphs PSD vs Frequency. How could I find a one value for frequency?
Also I have opposing jet in the blunt body. For this it has shown in the pressure has increased inside the shock wave. Would it be possible?
Thank you very much for your time.
