Class
    Foam::kqRWallFunctionFvPatchField

Group
    grpWallFunctions

Description
    This boundary condition provides a suitable condition for turbulence
    \c k, \c q, and \c R fields for the case of high Reynolds number flow using
    wall functions.

    It is a simple wrapper around the zero-gradient condition.

    \heading Patch usage

    Example of the boundary condition specification:
    \verbatim
    myPatch
    {
        type            kqRWallFunction;
    }
    \endverbatim
