Class
    Foam::yPlus

Group
    grpUtilitiesFunctionObjects

Description
    This function object evaluates and outputs turbulence y+ for turbulence
    models. The field is stored on the mesh database so that it can be
    retrieved and used for other applications.

    Example of function object specification to calculate the y+ (LES):
    \verbatim
    yPlus1
    {
        type        yPlus;
        functionObjectLibs ("libutilityFunctionObjects.so");
        ...
    }
    \endverbatim

        type         | Type name: yPlus        | yes         |
        phiName      | Name of flux field      | no          | phi
