alastormoody11 Senior Member Join Date: Jun 2009 Posts: 100 Rep Power: 16	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
