Insert inlet velocity waveform
 

Dear all,

I have a velocity waveform, given as a large set of points, and I would like to define it as the inlet velocity in my case file (in FLUENT). What is the best way to do that? I can build a profile file (UDF file), but I wonder if there is another way. I heard about FFT but I have no idea how to use this technique. Anyone?

Thanks,

Hila.
