Hello,
Once I open a .xmf file, if I close it and try to open it again I get these two errors:
ERROR: In vtkXdmfReader.cxx, line 487
vtkXdmfReader (000001BED83E0F50): Failed to read data.
ERROR: In vtkExecutive.cxx, line 741
vtkPVCompositeDataPipeline (000001BEB7F78A70): Algorithm vtkFileSeriesReader (000001BED8BA3E00) returned failure for request: vtkInformation (000001BEEDA2D190)
Debug: Off
Modified Time: 412731
Reference Count: 1
Registered Events: (none)
Request: REQUEST\_DATA
FORWARD\_DIRECTION: 0
ALGORITHM\_AFTER\_FORWARD: 1
FROM\_OUTPUT\_PORT: 0
This happens both with some file I have already opened and visualized and some I have not.
Can you please help me solving this problem?
Thank you in advance

Hi,
I am attaching the file
[T4621\_L.xmf](https://discourse.paraview.org/uploads/short-url/zw1QeijqAoIVLcuC4YNdGa6gRun.xmf) (2.3 KB)
I managed this problem saving the file in .pvd format but I am still interested in understanding why this happens.
Best,
Marta

I confirm that these file cannot be read by ParaView. But I do not know if this is a ParaView issue or a file issue. Investigation is needed.

The problem is that I was able to open it a first time and then I couldn’t do it anymore… I had to rerun the simulation and rewrite the .xmf file!
For now I will just save it with the .pvd format after opening it the first time, since this seems to work…

I wonder if some caching is getting confused here. Not sure what filter is doing such things though.

Wild guess here. Assuming Marta isn’t being fooled, the file is opened once. ParaView then (on closing) will write a configuration file. The file won’t open again. Issue with something in the configuration file? One way to test, Marta, is to blow away configuration files. Edit/ Reset to Default Settings. Backup the files please. If this fixes it, Kitware will probably want these files.
