Hi, everyone. I followed The FEniCSx tutorial to study how to calculate the displacement and the von Mises stress of an elastic body. I got the same deformation result as shown in the example, but when I calculated the stress I met some errors below: HDF5-DIAG: Error detected in HDF5 (1.14.3) MPI-…

You seem to be running the code in a mounted disk whgfs-fuse. Try running the same code in your home: if the error is not there anymore, then it is due to the mount options you chose.

That sounds like an error when trying to create the file itself. Is the disk mounted with the correct permissions? Is there enough free space?

I use a virtual machine in Win and run the code in root. I use the command ‘’ df -h’’ which shows that there is enough space. [space]

Thank you for your help!! It works and there is no error now. But I still cant get the image of the stress, the result I get like this: [图片] which is far from the result shown in the tutorial

Thanks for your advice. I changed the position and the code runs without error, but the result seems not right like this； [图片]

You may try Paraview, but your image looks nothing like the one in tutorial (assume we’re talking about the same demo): [image] Also you could print out some numbers.

It seems that we are talking about different ones. The result is like this: [图片] I’ll learn how to use Paraview, thanks for your help.

It is totally unexpected that I have exactly the same problem, I sourced export HDF5_USE_FILE_LOCKING=FALSE in .bash_profile, but nothing happened, the errors were still there. This is wired. Both 2019.1.0 docker image and standalone 2019.2.0.dev show same error. So may I ask what did you do?

I just gave up using Pyvista after trying many times. I export the result as a .xdmf file to visualize it in Paraview
