Error while trying example of 'Modeling hexagonal lattices'

Hi Paul Romano,
I tried the example that is provided which is ‘Modeling of Hexagonal lattices’. But, I got error. The screenshots are attached. Would you be able to help me out. Thank You.

Can you restart your jupyter kernel by simply clicking Kernel > Restart and Run All from the Jupyter menu?

Hi Karthik,

The exception that is shown indicates that the OpenMC executable did not complete successfully. To get further information. I would advise going to a command line in the same directory where you have your Jupyter notebook and running ‘openmc -p’ directly, which will give you more information on the error when OpenMC was run in plotting mode.

Best,
Paul
