Hello Ahmet,

What kind of flow features are you looking to plot? There are two main types of spectral analysis tools for acoustics:

1) FFT analysis/plotting for point data (.out files or imported unsteady data)

2) FFT analysis for surface data (FW-H .asd files only)

Did you set up solution monitors during your simulations and wrote the data to .out files (e.g. for pressure fluctuations at a point of interest)?
