Unable to visualize data from Firedrake in Paraview

[Arijit-Majumdar]

Hi,
I am running a 3D linear thermoelasticity problem with Firedrake. I created the mesh using gmsh and I exported the data as VTK file using the following commands
from firedrake.output import VTKFile
outfile = VTKFile("output.pvd")
outfile.write(T_soln, u_soln, alpha)

When I try to read the file in Paraview (version 5.10.1) I am getting the following error
ERROR: In /opt/glr/paraview/paraview-ci/build/superbuild/paraview/src/VTK/IO/XML/vtkXMLReader.cxx, line 306
vtkXMLUnstructuredGridReader (0x7fc7d4b41fd0): Error opening file /Users/arijitmajumdar/Downloads/output/output_0.vtu

I am not sure where the issue is coming from. I am providing a link to my code in colab for the simulation. Any help is greatly appreciated.

It looks like at least one other person has hit this issue. Unfortunately no one has responded to them so I am not sure what the issue. Does the error persist with different saved functions? With a different version of Paraview?

I am getting that problem with .vtu files and Paraview 5.11.2 on ubuntu also.

Other users reported that this issue was sorted out with Paraview 5.12 installation.

It works indeed. Thank you for that!
