Paraview crashes when opening xdmf files created with FEniCSx

Hello,

I am trying to open an xdmf file that was generated by running some code on FEniCSx, to visualize the results. But the software crashes when I hit the ‘Apply’ button after import. This only happens when I run the code on multiple processes. The output file generated by the exact same code when run in serial was handled by ParaView without any trouble.

Here are the files I am having trouble with.

s.h5 (91.8 KB)
s.xdmf (1.0 KB)

Thank you for any help I can get!

Is the file size of “s.h5” the same for serial and multiprocess calculations?

The file size in the serial case is slightly bigger. 94344 bytes compared to 94016 bytes. I am attaching the files for serial case, just in case.

s.h5 (92.1 KB)
s.xdmf (1.0 KB)

Thank you

I have no idea why, but naming the function instance when I create it in FEniCSx solves this problem for me. Perhaps a bug in the FEniCSx software.

Thank you
