Class
    Foam::functionObjects::yPlus

Description
    Evaluates and outputs turbulence y+ for models. Values written to
    time directories as field 'yPlus' or 'yPlus.<phase>'.

    Example of function object specification:
    \verbatim
    yPlus1
    {
        type        yPlus;
        libs        ("libfieldFunctionObjects.so");
        ...
    }
    \endverbatim

Usage
    \table
        Property | Description                | Required   | Default value
        type     | type name: yPlus           | yes        |
        phase    | phase name                 | no         |
    \endtable

    Note:
        Writing field 'yPlus' is done by default, but it can be overridden by
        defining an empty \c objects list. For details see writeLocalObjects.
