Dear FLUKA experts,
I am trying to model a simple problem using lattice cards for repeated structures. I have taken help from the following topic to prepare my input using the LATTICE feature of FLUKA:
My model consists of 9 cubes of iron containing smaller cylinders made of carbon. These cubes have been replicated using LATTICE card. Following is how the geometry looks like:
A planar photon beam of 1 MeV is incident on the assembly along one direction.
My objective here is to score photon flux within each small cylindrical regions (filled with Carbon). I am trying to use USRTRACK scorer for this purpose.
However, I am not sure how to score in all the smaller cylinders using USRTRACK card (both individually in each cylinder and also as an average over all cylinders) as it asks for one region where flux will be estimated. I thought about putting multiple USRTRACK cards. But in that case, I am not sure how to specify regions corresponding to each smaller cylinder. That is because in the region definitions, I have defined lattice unit regions using only the outermost solid. So, as such there is no separate region defined for the containing cylinders.
Please let me know about possible solutions to this issue. Following are my input files:
