Detailed Description

This boundary condition provides a wall constraint on the turbulent viscosity, i.e. nut, for low Reynolds number models. It sets nut to zero, and provides an access function to calculate y+.

Usage

Example of the boundary condition specification:

<patchName>
{
    // Mandatory entries (unmodifiable)
    type            nutLowReWallFunction;

    // Optional (inherited) entries
    ...
}

where the entries mean:

Property	Description	Type	Req'd	Dflt
type	Type name: nutLowReWallFunction	word	yes	-

The inherited entries are elaborated in:
