Hi,
I'm studing about turbulence and others topics about it. Because of that, I need to create a turbulence spectra in unstable simulation on fluent. Is it possible?
I alredy created some points to take a magnitude of velocity. The turbulence model is KE, but my target will be use Reynolds stress model.

I think the following links might help you:

You can compute any high order statistics you want, provided that you use DNS/LES formulation.

With RANS approach is imited the cut frenquancies and wave number you can 'see'. As wrote Filippo: LES or DNS
