Dear Fluka users and developpers,
I'm trying to simulate a 50 MeV / 10 ľA electron beam on a U238-C2
target, so far so good.
The resnuclei distribution seems to be quite as I expected.
When I calculate the radioactive decay "offline" with usersuwev program,
I get good results, still OK.
But, when I try the same "online" this time, using RADDECAY, IRRPROFILE,
DCYTIMES and DCYSCORE cards, I get a core dump before the end, but not
at the very beginning. The run goes normally till it crashes.
I would like to know what seems to be the problem.
I figure it's the RADDECAY option, since everything goes OK without it,
but I don't find where.
I don't get any understandable answer when using gdb command applied to
the core file.
I don't think that my machine has a memory problem or something like
that. I run on Redhat FC3.
Is it a problem of time left for termination (defined in START card) ? I
tried several termination times, with the same negative result.
Any clue ?
Thank you.
Sebastien
PS : Attach file is the used input file "target.inp"
