Hi Bastian,
I had/have a similar problem regarding parallel xdmf.
If you can’t find the xdmf2 reader, you should recompile paraview with setting your specific options. All that I can find is for VTK:
//Request building vtkIOXdmf2
Module_vtkIOXdmf2:BOOL=ON
//Request building vtkIOXdmf3
Module_vtkIOXdmf3:BOOL=ON
//Request building vtkIOParallelXdmf3
Module_vtkIOParallelXdmf3:BOOL=ON
//Request building vtkxdmf2
Module_vtkxdmf2:BOOL=ON
//Request building vtkxdmf3
Module_vtkxdmf3:BOOL=ON
But beware, I’m not an expert and just figuring those things out myself as those options are not very well documented (or at least I can’t find them!).
As I have a problem with partitioning my large unstructered grid I want to use the D3 filter who does a great job. The only problem here is that every process reads in the complete mesh, so that the memory footprint is very high and not feasible in my case. That’s why I try to develop a sequential partitioning program, that saves the output in VTK, as this file format is very well implemented in paraview and tests with a smaller dataset gave me very good results in parallel I/O.
Greetings,
Chris
