Class
    Foam::nutUTabulatedWallFunctionFvPatchScalarField

Group
    grpWallFunctions

Description
    This boundary condition provides a wall constraint on the turbulent
    viscosity (i.e. \c nut) based on velocity (i.e. \c U), for low- and
    high-Reynolds number applications.

    As input, the user specifies a look-up table of \c u+ as a function of
    near-wall Reynolds number.

    The table should be located in the \c $FOAM_CASE/constant directory.

Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        // Mandatory entries
        type            nutTabulatedWallFunction;
        uPlusTable      myUPlusTable;

        // Inherited entries
        ...
    }
    \endverbatim

    where the entries mean:
    \table
      Property    | Description                          | Type | Reqd | Deflt
      type        | Type name: nutUTabulatedWallFunction | word | yes  | -
      uPlusTable  | u+ as a function of Re table name    | word | yes  | -
    \endtable

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

Note
  - The tables are not registered since the same table object may be used for
    more than one patch.
