Class
    Foam::compressible::RASModels::nutkFilmWallFunctionFvPatchScalarField
 
Group
    grpSurfaceFilmBoundaryConditions grpCmpWallFunctions
 
Description
    This boundary condition provides a turbulent viscosity condition when
    using wall functions, based on turbulence kinetic energy, for use with
    surface film models.
 
    \heading Patch usage
 
    Example of the boundary condition specification:
    \verbatim
    myPatch
    {
        type            nutkFilmWallFunction;
        value           uniform 0;
    }
    \endverbatim
