Dear FLUKA experts:
For an experimental beam line I am designing, I would like to score the neutrinos emitted by the decay of pions and muons. I have used the card DISCARD, setting -neutrinoe/m/t and -antineutrinoe/m/t, and as scorers I have used USRYIELD and USRBDX. I am simulating pions of 12 GeV and I am expecting them to have decayed by the end of my beam line. However, when I try to plot the USRYIELD with neutrinos I see the following error message:
line 0: all points y value undefined!
ERROR: Gnuplot errors or warnings found
Is there some other card that I should add to my input to “see” the neutrinos? Or is it just the result of my simulation an empty file?
Thank you for your help.
Anna
