Class
    Foam::vtk::internalWriter

Description
    Write an OpenFOAM volume (internal) geometry and internal fields
    as a vtu file or a legacy vtk file.

    The file output states are managed by the Foam::vtk::fileWriter class.
    FieldData (eg, TimeValue) must appear before any geometry pieces.

Note
    Parallel output is combined into a single Piece without point merging,
    which is similar to using multi-piece data sets, but allows more
    convenient creation as a streaming process.
    In the future, the duplicate points at processor connections
    may be addressed using ghost points.
