I am using OpenMC with multigroup cross sections and I get the following warnings.
WARNING: 2entries in the Multiplicity Matrix were changed from 0 to 1
WARNING: 1entries in the Multiplicity Matrix were changed from 0 to 1
WARNING: 1entries in the Multiplicity Matrix were changed from 0 to 1

WARNING: 1entries in the Multiplicity Matrix were changed from 0 to 1
WARNING: 1entries in the Multiplicity Matrix were changed from 0 to 1
WARNING: 1entries in the Multiplicity Matrix were changed from 0 to 1
Is this something I need to be concerned about? Could you please explain what is going on here?
I have included my multigroup h5 file here as well.
Thank you!
