I was wondering if anyone has used dnsFoam recently or knows how to use dnsFoam.
The problem that I am facing, is that I can't find any case setup where I actually see a energy cascade in the Ek-k plot. I only see a energy build up at very low wavenumbers.
I ran the tutorial case and I have played around with the forcing input parameters and grid resolution, however, I still can't see anything looking like a energy cascade.
Does any know how to setup dnsFoam to actually see a energy cascade in the Ek-k plot?
