Your input file cannot run because it is not currently possible with FLUKA to score DOSEQLET with a USRYIELD card. Try to score another particle by changing the “Part.” option of your “let2” detector (in Flair) or the WHAT(2) of the first card directly in the input file.

I suggest you check the .err files that are generated when you run FLUKA. These could be insightful to determine the issue.

thank you, I ''ll try it
