1 Wall Treatment

The LES wall function in OpenFOAM assumes an instantaneous correlation between the the velocity at the first off-the-wall grid point and the wall shear using an assumed velocity distribution (usually done). In the particular case of OpenFOAM, the Spalding's continuous law is used.
