[Paraview] Parallel VTK file format with multiple levels

[Xunlei Wu]

Hi,

I would like to use .pvtu to represent a multi-level unstructured grid by stating

===level 1 PVTU===
<VTKFile type="PUnstructuredGrid" version="0.1" byte_order="LittleEndian">
  <PUnstructuredGrid GhostLevel="1">
...
    <Piece Source="energy_1.0/nsp.pvtu"/>
    <Piece Source="energy_2.0/nsp.pvtu"/>
  </PUnstructuredGrid>
</VTKFile>


===level 0 PVTU (energy_1.0/nsp.pvtu)===
<VTKFile type="PUnstructuredGrid" version="0.1" byte_order="LittleEndian">
  <PUnstructuredGrid GhostLevel="0">
...
    <Piece Source="nsp_316.vtu"/>
...
    <Piece Source="nsp_523.vtu"/>
  </PUnstructuredGrid>
</VTKFile>

After constructing these PVTU's and VTU's, I opened the level 1 PVTU and got below errors: ERROR: In ..\..\..\ParaViewSrc\VTK\IO\vtkXMLPDataReader.cxx, line 364 vtkXMLPUnstructuredGridReader (00000000055D5860): File for piece 0 cannot be read. Note loading level 0 PVTU's and individual VTU's are of no error in ParaView. Did I miss anything? I could not find an example showing multi-level parallel VTK data construction. Would you please help? Thanks a lot.

Best,
