The end goal is to be able to plot the amplitude as a contour at each point for a given frequency. I have attached an incredibly crude...

Let me try and describe my problem once again. I'm not looking for FFT analysis at a single point, rather all points in the domain. So, rather than...

So, you're basically performing FFT at each data point using a reduced set of data (one temporal point for each saved time step). So, rather than doing FFT of a single probe location using 2,048...

Replies: 9 OpenFOAM FFT of Entire Transient Data Views: 4,438 Posted By minger OpenFOAM FFT of Entire Transient Data I was wondering if there was any utility or outside code that could perform an FFT analysis of an entire unsteady solution set. By that, I mean if I run my analysis and determine the fundamental...
