Hi Deepak,
Coming back to your question, if you want to filter an ENERGY scoring to the direct contribution of primaries (excluding secondaries), you would need to apply that filter via the comscw.f subroutine (actually it is a function), where you would set COMSCW = ONEONE for primaries (IF condition).
Fluka labels primaries in the logical variable LOFLK (in the FLKSTK stack) in the default template of source.f routine, i.e. you don’t actually need to add any additional latch for that specific property.
So you would have something like this in comscw.f
IF (LOFLK) THEN
COMSCW = ONEONE
ELSE
COMSCW = ZERZER
END IF
Remember also to tell FLUKA that you want to enable this feature by 1) adding a USERWEIG card with WHAT(6)>0 and 2) including your edited comscw.f in your compilation instruction (along with source.f).
