Hi guys,


I verified the k value in near wall cell with the formulation of k in boundary layer (Utau^2/sqrtCu) and I found they are not consistent with each other. I am confused that kqrwallfunction is applied at the wall for k, which is similar to zerogradient condition. I did not find the code how to calculate the value in near wall cell. Do you have any ideas about this issue?


Many thanks,
