Stop point wise neutron data not found

Hello dear experts,

I have got this point wise neutron data not found error. I tried to add LOW-PWXS card but as soon as I add this card, flair window closes itself. In ubuntu terminal says “Attribute error-segmentation fault (core dumped)”

Does anyone suggest how to fix it, please?

Best regards,
gulmen

Dear gulmen,

please install the necessary libraries. See: FLUKA libraries for low-energy neutron pointwise interaction cross sections | The official CERN FLUKA website.

Cheers,
David
