Re: Run aborts with more histories

Hi
the problem is in the USRYIELD definition : you ask the scoring of
neutrons exiting from inelastic interactions ( -1 and -2 as "regions"),
and at the same time you ask for fluence scoring ( what(6)=6 in the second
card ). In order to score fluence, a reference surface is needed, but in
the case of yield from single interactions there is no reference surface..
and the code crashes. You should put what(6)=3 (plain double differential
yield) in the second definition card
Let me know
Paola
