import openmc
Sp=openmc.statepoint(‘statepoint.100.h5’)

This should solve your problem.

You’ve installed openmc successfully. But sorry to say, i don’t know why it isn’t working now.

Hi @imtiaj_hossain , I have a few wonders about the jupyter notebook on window sub linux. I wonder the jupyter notebook can not support on the WSL? so it shows the red error.

This maybe effects when I use jupyter notebook to load statepoint h5 file and It show error that it can not find the data. Do you have any ideas?

Cheers,

@Yos The error you’re getting says that the statepoint file is not compatible with your version of OpenMC. You’ll need to rerun your simulation to get a new statepoint file, at which point you should be able to load it in the Python API.

Thank you @paulromano for your suggestions. Now I can load it. I think it is because I don’t upgrade h5py to the latest version when I upgraded openmc-10 to openmc-11.
