I had to prepare a fluka input using a python code which reads material data. For some materials, not all the atoms are present (for example, see f2 M2, f7, M7 entry in mat26 and mat27). My query is, is it right to keep f2 and M2 blank in the compound block? I mean there is no error while running, but I want to confirm if this is allowed or will this input skip any compound after the blank entry (i.e. f3 M3 and so on … ).
I tested by keeping the first entry f1, M1 blank and rest of them were filled, but then I got errors. So I am afraid that, although the input is running, it is not reading any compound entry after the blank entry.
I hope I have conveyed my query properly, otherwise please let me know.
