Detailed Description

Write faces/points (optionally with fields) as a vtp 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.

Here is the call graph for this function:

◆ writeGeometry()

bool writeGeometry ( )
virtual

Dummy write mesh topology method - Fatal if called.

Provided for special-purpose writers that do not hold their own geomety, but use writePolyGeometry() directly

Implements fileWriter.

Reimplemented in GenericPatchWriter< PatchType >, lineWriter, and surfaceWriter.

◆ writeLineGeometry()

bool writeLineGeometry ( const pointField points,
const edgeList edges

Low-level write edge/point topology. Normally used by writeGeometry() in a derived class

Also writes the file header if not previously written.

Note
Must be called prior to writing CellData or PointData
