Detailed Description

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

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            nutLowReWallFunction;

        // Optional entries
    }
