ayoros New Member Join Date: Mar 2009 Posts: 29 Rep Power: 17	Hi all, and good Monday morning for everyone (at least for those close to my meridian time) ! About the nuSgsWallFunction, I still have some doubts. Do the yPlus values have to be higher than say 11 for the wall function to be effective ? Or can LES wall function cope with yPlus values from say 1 to 30 ? Also, if I don't use wall function, am I right applying 'zeroGradient' for nuSgs boundary condition at walls ? Thanks in advance, Fabien
