Dear fluka experts,
I want to simulate ADS problem with 60 MeV proton beam impinging to PbBi target surrounded by a subcritical core using FLAIR. My work is to detect all primary neutrons that scatter by using fluscw.f to write down neutron properties including IJ, TXX, TYY, TZZ, WEE, XX, YY, ZZ, PLA into .txt file and ready to convert to hdf5 format for calculating as fix-source calculation in OPENMC.
On my fluscw.f, I have chosen yield estimator which I thought would give me all desired neutron properties, and other two cards, USRBIN and USRBDX cards in my input it would give me neutron fluence with unit neutrons/cm^2 per primary(which is neutron distribution in the area) and neutron fluence interval in energy from 1E-9 to 0.6 GeV at the target to target clad region respectively. Actually, in USRBDX output I want to plot from target to vacuum region but the result in tab. lis file columns 3 and 4 become zero values and can’t generate a plot so I decided to plot in the target region instead as shown in the input.
My questions are 1.Did I do it right to gather all neutron properties? I have read about PHYSICS card but I’m not sure is it needed or not, please give me some advice.
2.Why can’t I plot usrbdx output from target to vacuum area?
I have attached my ads.inp, my plot, and neutron properties in .txt file that I got below here.
Thanks for considering my problem.
