Re: [fluka-discuss]: Gas production using new FLUKA functionality in 2011.2x.8

Hi

the issue is that you asked for track length distributed binnings
for RES-NUCL scoring, hence the code interprets this request as
a track length fluence scoring which is not what you want.

If you change WHAT(1) of the USRBIN cards from 10 to 0 you'll
find that the results from your USRBIN's and your RESNUCL's estimators
are identical.

Indeed it would be advisable to stop the code if a USRBIN with RES-NUCL
is requested with scoring distributed along the track, since it is
likely not what the users wants, we'll introduce a protection for this in
the next respins/releases.

                    Hope this helps!
                   The Fluka developers
