Usage

Property	Description	Required	Default value
`Ks`	sand-grain roughness height	yes
`Cs`	roughness constant	yes

Parameter ranges

roughness height (Ks) = sand-grain roughness (0 for smooth walls)
roughness constant (Cs) = 0.5 - 1.0

Example of the boundary condition specification:

    <patchName>
    {
        type            nutURoughWallFunction;
        Ks              uniform 1e-5;
        Cs              uniform 0.5;
        value           uniform 0;
    }
