Dear Hans,
I am not sure that comscw.f is the right user routine for your problem. Residual nuclei are best
filtered via usrrnc.f

Dear Hans, I'm not sure you are evaluating the same quantity (apart from the prompt products you loose scoring after 1s of irradiation , which shouldn't be much)
What I see naively is that your comscw.f is always returning "ONEONE", maybe you want to return something else if it's not a Sodium isotope?
Best,

Dear Fluka experts,
When I calculate the production of a specific Na-24 in a piece of
aluminum that is hit by an electron beam in two different ways, i.e.
using the RESNUCLE or USRBIN (and RADDECAY,DCYTIMES,IRRPROFI,DCYSCORE
with comscw.f to get the right isotope), I get two very different
results: (4.70p/m0.29)xe-8 nuclei/cm3 with RESNUCLE and
(4.355p/m0.067)xe-2 nuclei/cm3 with USRBIN. The USRBIN result has been
divided by the decay constant to get number of nuclei per cm3. The input
file and comscw.f routine are attached. Obviously I am doing something
wrong, but I cannot find the mistake. Any suggestions are highly
appreciated.
Yours truly,
Hans Beijers
