XMLPUnstructuredGridWriter

Repository source: XMLPUnstructuredGridWriter

Description

vtkXMLPUnstructuredGridWriter object writes the PVTK XML UnstructuredGrid file format.

One unstructured grid input can be written into a parallel file format with any number of pieces spread across files.

The standard extension for this writer's file format is "pvtu". This writer uses vtkXMLUnstructuredGridWriter to write the individual piece files.
