alastormoody11 is on a distinguished road
Has anyone used the FFT option in STARCCM+ to process data.

I am trying to use the the FFT to process force variation in a cube to determine its sloshing frequency.

Can anyone tell me what options I need to choose so as to accomplish this? I am a bit confused regarding the frequency range option specially since that is what I am trying to find out.

Also where does the FFT option come from, coz when I right clicked on the data process functions it just showed the options of Fourier and inverse Fourier but no FFT.

Any help would be appreaciated
