Detailed Description

This boundary condition provides a wall constraint on the turbulent kinematic viscosity, i.e. nut, when using wall functions, based on velocity, U.

Usage

Property	Description	Required	Default value
`Cmu`	Model coefficient	no	0.09
`kappa`	Von Karman constant	no	0.41
`E`	Model coefficient	no	9.8

Example of the boundary condition specification:

    <patchName>
    {
        // Mandatory entries
        type            nutUWallFunction;

        // Optional entries
    }

See also: Foam::nutWallFunctionFvPatchScalarField

Note: Suffers from non-exact restart since correctNut() (called through turbulence->validate) returns a slightly different value every time it is called. See nutUSpaldingWallFunctionFvPatchScalarField.C
