Detailed Description

template<class PatchType>
class Foam::vtk::GenericPatchWriter< PatchType >

Write concrete PrimitivePatch faces/points (optionally with fields) as a vtp file or a legacy vtk file. The patch type is limited to representations of polygon faces and 3D points and must support the following methods:

- localPoints()

  • localFaces()

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.
