object s in LES 0 time directory. Which turbulence model is it used for?

HappyS5 · July 9, 2019, 19:05

Hello,

I am doing a tutorial on turbulence modeling. Unfortunately, the tutorial uses a different version of OF.

In the tutorial, he has a nutsgs file. I have nuTilda and an s file in the 0 time directory. In OF version 5, my version, does the s replace nutsgs? What turbulence model is the s file used for in OF?

nuTilda is for spalart almaras model, why do you have that for an LES tutorial?

old versions used nuSgs, newer versions have renamed it to nut. What's nutsgs?

s file is something else entirely. Do you have some custom code that does more than just LES?
