Class
    Foam::nutkWallFunctionFvPatchScalarField

Group
    grpWallFunctions

Description
    This boundary condition provides a wall constraint on the turbulent
    viscosity, i.e. \c nut, based on the turbulent kinetic energy,
    i.e. \c k, for for low- and high-Reynolds number turbulence models.

Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        // Mandatory entries (unmodifiable)
        type            nutkWallFunction;

        // Optional (inherited) entries
        ...
    }
    \endverbatim

    where the entries mean:
    \table
      Property  | Description                   | Type | Req'd  | Dflt
      type      | Type name: nutkWallFunction   | word | yes    | -
    \endtable

    The inherited entries are elaborated in:
      - \link nutWallFunctionFvPatchScalarField.H \endlink

Note
    - See \link nutWallFunctionFvPatchScalarField.H \endlink for the wall
    function blending treatments.
