Hello, I am trying to follow the guide here https://openmc.readthedocs.io/en/stable/usersguide/processing.html?highlight=plot%20tallies

plotting in 2D.

I want to plot a mesh tally in two dimension. I am running the

openmc-plot-mesh-tally

directly in my project directory. I got this below error

Sharifs-MacBook-Pro:JSA sharifabudarda$ openmc-plot-mesh-tally

Looks like this could be a bug in openmc-plot-mesh-tally. See this stack overflow post with a similar problem and solution. If you’re comfortable, you can try making changes in the openmc-plot-mesh-tally script, adding the following:

import matplotlib
matplotlib.use(“TkAgg”)

Hello Dr, i was using mac system when i post this. In mac system this does not work and shows this error. I move into my linux system and run the same command there. It worked. In both platform i have openmc veraion 10 installed. I will follow up with your guide above. Thanks for the reply.

Hello, Dr, Can you share me the directory of the script file stored in? I am in mac OS X10.14. I have miniconda3 installed. I looked for the main script file I found two of the script

‎⁨MAC OS X⁩ ▸ ⁨Users⁩ ▸ ⁨xxxxx ▸ ⁨miniconda3⁩ ▸ ⁨pkgs⁩ ▸ ⁨openmc-0.10.0-0⁩ ▸ ⁨lib⁩ ▸ ⁨python3.6⁩ ▸ ⁨site-packages⁩ ▸ ⁨openmc-0.10.0-py3.6-macosx-10.9-x86_64.egg-info⁩ ▸ ⁨scripts⁩

and another one is on

‎⁨MAC OS X⁩ ▸ ⁨Users⁩ ▸ ⁨sharifabudarda⁩ ▸ ⁨miniconda3⁩ ▸ ⁨pkgs⁩ ▸ ⁨openmc-0.10.0-py36hb8ecfd0_2⁩ ▸ ⁨lib⁩ ▸ ⁨python3.6⁩ ▸ ⁨site-packages⁩ ▸ ⁨openmc-0.10.0-py3.6-macosx-10.9-x86_64.egg-info⁩ ▸ ⁨scripts⁩

I tried to change in both of them as the below image shows. Please reply if I am doing right. This is only in mac OS. In linux, it works. Thanks.

I’m not too sure about the exact path on macOS, but in your case I would probably just change it in both. The change that you made looks correct to me.

Best,
Paul

Hello, Dr, Ok, I did update of the miniconda packages by

conda update conda

and also the openmc package by

conda update openmc

I also installed vtk package for conda and also update python package

now, if I run the openmc-plot-mesh-tally I am having a different issue. The log is below. can you guide what I can do here? Thanks.

Hello Dr, I was able to resolve the issue. Here is what I did, In

“/Users/sharifabudarda/miniconda3/lib/python3.6/site-packages/openmc-0.10.0-py3.6-macosx-10.9-x86_64.egg-info/scripts/openmc-plot-mesh-tally” I changed the

NavigationToolbar2TkAgg
into
NavigationToolbar2Tk

That does it. For me, Now I am able to run openmc-plot-mesh-tally command. Thanks for your guide.
