Hi Chi Hin

Thanks for your reply. Yes I meant the spanwise averaging. But I guess this method would give a 2-D expansion containing the mean mode of instantaneous quantities.

What can I do if I'd also want to spanwise-average quantities such as Reynolds stresses?

Kind regards

Hi Syavash,

Are you referring to averaging across the homogeneous (z-th) direction? i.e the Fourier 0-th mode.

If so, you can use FieldConvert -m meanmode. Hope this helps

Cheers

Dear All,

How can I average the solutions of planes across the homogenous direction in a Quasi 3-D simulation?

Kind regards
