Detailed Description

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

Usage

Example of the boundary condition specification:

<patchName>
{
    // Mandatory entries
    type            nutUWallFunction;

    // Inherited entries
    ...
}

where the entries mean:

Property	Description	Type	Reqd	Deflt
`type`	Type name: nutUWallFunction	word	yes	-

The inherited entries are elaborated in:

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.
