zebu83 is on a distinguished road
I modify "channelOodles" tutorial like this: 3.5 x 2 x 2 with 80*180*120, and I have Retau = 180 (more or less).
Your resolution is better then my resolution, but what about your Retau?

Are your results good? Is it like Moser or Marusic DNS?

The most evident difference are urms, my urms are 2.5 instead 2.8! But other quantities are not so bad. I thik that my channel is too small, and also finite volume are less conservative than spectral method, for example.

What do you thik about this?
I am interesting on it.
What I want to do it's a good channel DNS, but it is not so simple that I thought!!!

Bye
