Hello,
I've attached my input & flair file and hope that if you take a look at it
you'll see what I've been trying to do.
************************************************************************
Thanks for the good advice, my example runs without errors now.
Right now I'm trying to create simulation that calculates the energy
spectrum (i.e Neutron Energy vs Neutron Fluence) for a beam of neutrons
20 cm after interacting with a steel target. I'm not entirely sure which
detector to use in this case, because I am getting slightly confused by
the detector definitions in the manual. Could you help me decide which
detector to use and possibly explain to me how to set it up in a simple
way? I have used a usrbdx, with two adjacent cubes defining the upstream
and downstream of the detector. Since that didn't work, I've tried to
create a usrcoll detector defined by a simple vacuum region.
All in all I think I'm always getting exclusively zero for the fluence at
any energy. I Hope you can help. I feel like I understand a lot about
whats going on, but just not enough to really get going.
Thanks again,
Jay
