Hi all, Sorry for the silly question, but I’m a bit confused on how to make a slice plot. I’m using Jupyter, and when I run my code with !openmc --plot the .png file is generated but it is empty due to the warning of zsh:1: number expected When I use openmc.plot_geometry() or openmc.plot_inline…

Hi all, I found a workaround by using the universe.plot() command instead of trying to plot from a .XML file using the openmc.plot_geometry(), the command line prompt, openmc --p, or the openmc.plot_inline() function. Specifically, creating a universe with all of my cells and then creating a single…

Sorry to hear this is giving you trouble @madhofs . That’s really strange. If you list the resulting png file from the !openmc --plot command with ls -l, what do you see?

Hello @pshriwise , thanks for your response! So sorry for the delayed reply. When I run !openmc --plot and then use ls -l in the directory, the line for the .png appears as -rw-r--r-- 1 username staff 0 Dec 5 09:49 plot_5.png Let me know if I can provide anything else for you. Thanks!

Thanks for the info @madhofs . It appears that the library found for the openmc executable at runtime isn’t the same as the one it was linked to when it was built. Do you see the same warning if you run openmc -p from the command line (in the same directory with your jupyter notebook)?

I have the same problem. When running the plot() function on my universe, it gives me RuntimeError: OpenMC aborted unexpectedly. If i run openmc -p from the same directory as my jupyter notebook, the following is written out (openmc-env) <retracted> % openmc -p %%%%%…

Hi @paulromano , thanks for the response! This may be a silly question, but if I were to install OpenMC from source as @sop_kretzschmar did, I assume this means that I cannot install it with Conda/Anaconda? I noticed that to install the OpenMC Python package, you must use a pip command, and I have ha…

Hi @pshriwise , when I run OpenMC from the command line with openmc -p , the following prints: =======================> PLOTTING SUMMARY <======================== Plot ID: 1 Plot file: plot_1.png Universe depth: -1 Plot Type: Slice Origin: 0 0 0 Width: 100 20 Coloring: Cells …

Hey @madhofs , could you send me an example of your code? I’m having the same issue and can’t get it to plot in-line in Jupyter Notebook. I’m doing: Create root Cell root_cell = openmc.Cell(name=‘root cell’) root_cell.fill = universe Add boundary planes root_cell.region = -outer_surface Create …

Hi @srichr221 , here you go! First, I create the cells and whatnot in my first universe. This is only one of a few cells I have, so this doesn’t define the entire universe, but it gives you an idea of how I create it. Geometry for Beryllium Reflector (Source) innerCylinder = openmc.ZCylinder(x0=-4…

I am having a similar issue with openmc compiled from source on INL’s hpc: Processing plot 1: plot_1.png… libpng warning: Application built with libpng-1.6.37 but running with 1.5.13 Segmentation fault (core dumped)
