Detailed 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.
