Dear FLUKA Experts, In the attached input file, I want to score Dose-Eq. at z=56 (top surface) of the geometry. I used four USRBIN cards: x-y-z, z= 56 to 57, y = -0.5 to 0.5, x = -59.5 to 59.5 (119 bins), Volume of one bin: 1cc x-y-z, z= 56 to 58, y = -1 to 1, x = -59 to 59 (59 bins), Volume of o…

Dear @jyoti.grg , I have run your input with 30 million primaries after having add a few USRBINs to it. I added a large Cartesian USRBIN to look at the particle fluence: USRBIN 10. ALL-PART -24 50 50 60ap USRBIN -50 -50 20 …

Dear @jyoti.grg , You are in the same situation you were in February ( Relation between errors in successive scoring bins ). 1-As I already told you, you should not use X-Y-Z USRBIN having 1 single bin in two dimensions, create instead a X-Y-Z USRBIN that while having 1 bin in z can instead create an…

Dear Expert I was scoring From -x to +x and -y to +y, I kept a single usrbin from x = -59 to 59 (at the whole plane) and I kept two different usrbin at x = -32.1 to -33.1 and x = 32.1 to 33.1. The results are asymmetrical in both the cases. There is a sudden increase in DOSE EQ values near the ai…
