Class
    Foam::nutUWallFunctionFvPatchScalarField
 
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 turbulence models.
 
Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        // Mandatory entries (unmodifiable)
        type            nutUWallFunction;
 
        // Optional (inherited) entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property  | Description                    | Type   | Req'd  | Dflt
      type      | Type name: nutUWallFunction    | word   | yes    | -
    \endtable
 
    The inherited entries are elaborated in:
      - \link nutWallFunctionFvPatchScalarField.H \endlink
 
Note
    - Suffers from non-exact restart since \c correctNut() (called through
    \c turbulence->validate) returns a slightly different value every time
    it is called.
    See \link nutUSpaldingWallFunctionFvPatchScalarField.C \endlink.
    - See \link nutWallFunctionFvPatchScalarField.H \endlink for the wall
    function blending treatments.
