Cross section HDF5 file 'c5g7.h5' does not exist

[samiullah27]

Hi.

I am running this file using docker and got this error at line "openmc.run()", saying "Cross section HDF5 file 'c5g7.h5' does not exist". Now I have downloaded ENDF/B-VIII.0 ACE data which has lib80x_hdf5 folder with h5 files along with cross_section.xml. At first, I simply run the script and got this error but for the second time, I set my environment variable to this folder using the following command after importing the volume from my computer which is given below:

import os
os.environ['OPENMC_CROSS_SECTIONS']='/home/workspace/cross_sections.xml'

Now, this command has helped me with previous exercises but for this one, it didn't work. I have also tried writing "OPENMC_MG_


CROSS_SECTIONS" in os.environ but it's still the same. I really appreciate your help on this one

Regards,
Sami
