class KnownWallShearStressWallModelFvPatchScalarField : public wallModelFvPatchScalarField

Wall model that uses the values of the magnitude of the mean wall shear stress known a priori, for example, from a RANS precursor or an analytical solution.

Requires field tauWall with the values of the magnitude of the mean wall shear stress to be present. The model converts that prescribed stress into the wall eddy viscosity needed to realize the same stress with the current wall-normal velocity gradient.
