two basic questions
 

Hi guys

I have two question:

1) Which wall model is used in LES for near wall modelling. Is it wall functions?

2) What is difference between average courant number and RMS courant number. In LES documentation they recommend courant number of 0.5-1 for LES, but i have Max courant and RMS courant during the run. No avearge courant number!
