Spatial Fourier Transform (DFT/FFT)

TomWaits · August 15, 2018, 23:28

Hi all,
Is there a way to extract the fourier transform of a 3-D domain in terms of the spatial frequency; my Data>Fourier Transform is greyed out.

Thank you,
Tom Waits

The Fourier Transform currently is only supported in line plots. So to use Tecplot's Fourier methods, you must either extract a line or take an average to get this into a line to analyze.

We would be interested in your workflow of this, so for more specific directions please contact support@tecplot.com
