LES calculations
 
Hi everybody,

I am running LES simulations and have some non-understandings:
  • running pisoFoam gives me additional fields k0, ddt0(k), ddt0(U), U0 . What are these fields?
  • I am using "standard" wall functions (kqRWallFunction). How can I check my y+ ?
  • I don't know about the relaxation factors: Do I have to use them?
  • I thought there were a "internal loop" in PISO algorythm. How to control it?
Thanks for any kinf of help!
