Class
    Foam::vtk::patchWriter
 
Description
    Write OpenFOAM patches and patch fields in VTP or legacy vtk format.
 
    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.
