Class
    Foam::nutUTabulatedWallFunctionFvPatchScalarField
 
Group
    grpWallFunctions
 
Description
    This boundary condition provides a wall constraint on the turbulent
    kinematic viscosity, i.e. \c nut, when using wall functions, based on
    velocity, i.e. \c U.
 
    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 $FOAM_CASE/constant directory.
 
Usage
    \table
        Property     | Description             | Required    | Default value
        uPlusTable   | U+ as a function of Re table name | yes |
        Cmu          | Model coefficient       | no          | 0.09
        kappa        | Von Karman constant     | no          | 0.41
        E            | Model coefficient       | no          | 9.8
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        // Mandatory entries
        type            nutTabulatedWallFunction;
        uPlusTable      myUPlusTable;
 
        // Optional entries
    }
    \endverbatim
 
Note
    The tables are not registered since the same table object may be used for
    more than one patch.
