[Bugami]

Hi...
I am using openmc through anaconda3 and start Modelling a Pin-Cell. when I run the code, error showed me there is no cross_sections.xml. how to have cross_sections.xml in order to run the code?

Thank you in advance...

Hi @Bugami. Thanks for trying out OpenMC!

I'll refer you to the user's guide section on cross section configuration. We have a number of pre-processed cross section datasets at https://openmc.org/.

If you have further questions along these lines, the OpenMC discussion forum is a good resource for this kind of question or any other issues you may run into.

@Bugami you might also be interested in this package https://github.com/openmc-data-storage/openmc_data_downloader which can download the nuclear data required for your materials and set the cross_section.xml See the end of the readme.md for examples.
