velikaDjoka New Member Join Date: Mar 2021 Posts: 6 Rep Power: 5	Hello, In the k-omega SST model I know that at values of y+<11.25 The model k-omega is used. And this model do not need wall functions. If the y+>11.25, the k-epsilon is used. Normally, when we select the k-epsilon model (not k-omega SST) we can select the wall function. While in k-omega SST, it is not possible. My question is: Does the k-omega SST apply a wall function if the y+>11.25 ( when the k-epsilon is used ) ?
