Class
    Foam::nutUWallFunctionFvPatchScalarField
 
Group
    grpWallFunctions
 
Description
    This boundary condition provides a wall function for the turbulent
    viscosity (i.e. \c nut) based on velocity (i.e. \c U) for low- and
    high-Reynolds number applications.
 
Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        // Mandatory entries
        type            nutUWallFunction;
 
        // Inherited entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property  | Description                    | Type   | Reqd | Deflt
      type      | Type name: nutUWallFunction    | word   | yes  | -
    \endtable
 
    The inherited entries are elaborated in:
      - \link nutWallFunctionFvPatchScalarField.H \endlink
      - \link wallFunctionBlenders.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.
