Even with SetNumberOfPieces(4), only 2 files (Test.pvtu and Test_0.vtu) are generated.

#include <vtkSphereSource.h>
#include <vtkXMLPUnstructuredGridWriter.h>

int main(int, char *[])
{
  vtkSmartPointer<vtkSphereSource> sphereSource =
    vtkSmartPointer<vtkSphereSource>::New();
  sphereSource->Update();

  vtkSmartPointer<vtkDelaunay3D> delaunay =
    vtkSmartPointer<vtkDelaunay3D>::New();
  delaunay->SetInputConnection(sphereSource->GetOutputPort());
  delaunay->Update();

  vtkSmartPointer<vtkXMLPUnstructuredGridWriter> writer =
    vtkSmartPointer<vtkXMLPUnstructuredGridWriter>::New();
  writer->SetInputConnection(delaunay->GetOutputPort());
  writer->SetFileName("Test.pvtu");
  writer->SetNumberOfPieces(4);
  writer->SetStartPiece(0);
  writer->SetEndPiece(3);
  writer->Update();

  return EXIT_SUCCESS;

Download and Build XMLPUnstructuredGridWriter

Click here to download XMLPUnstructuredGridWriter. and its CMakeLists.txt file.

Once the tarball XMLPUnstructuredGridWriter.tar has been downloaded and extracted,

cd XMLPUnstructuredGridWriter/build 
  • If VTK is installed:
cmake ..
  • If VTK is not installed but compiled on your system, you will need to specify the path to your VTK build:
cmake -DVTK_DIR:PATH=/home/me/vtk_build ..

Build the project:

make

and run it:

./XMLPUnstructuredGridWriter

WINDOWS USERS PLEASE NOTE: Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time.
