Introducing openmc-plot a browser based option for plotting openmc geometry mesh tallies and dagmc geometry

Announcements

Version 0.2.1 release of openmc-plot is now live
https://openmc-plot.xsplot.com

It includes faster geometry plotting and support for dagmc model plotting.

The locally installed version runs a bit faster and more reliably than the webserver deployed version
pip install openmc_plot then openmc_plot to run

Hi Shimwell
I was using xsplot.com server for viewing OpenMc geometry. It worked fine for a while. It now gives

Also my install of this on MacBook is having trouble. Any help would be appreciated.

Thanks for letting me know.

Are you able to show a screen shot of the error and i can look into it.

All the best

I have just updated the pypi openmc_plot package. Not had time to do the website yet. But you could install and plot locally with

I have tried local install. Goes through steps until I select xml file. Here is the error I get

Ah yes sorry i think it needs the some features on the dev branch of openmc to work. Perhaps the next release of openmc is not far away.

Hi Richard

Sounds like openmc_plot needs an update. In the meantime perhaps just use the openmc_source_plotter directly if you want that functionality.

Here is an example
openmc_source_plotter/examples/example_plot_source_energy.py at main · fusion-energy/openmc_source_plotter (github.com)

Thanks, I will try it
