Creating custom source

Dear Experts,

I have cross-section, and from it i can get particles momentum direction and momentum. For example i can generate file with data for number of primaries i need. For example (part1 E=100 cosx = 1 cosy = 0 cosz = 0). Can i put this file inside Fluka source defining routines?

Dear Semyon,

yes, it is possible. You may have a look at the source_newgen.f user routine, especially it’s external phase space file. (13.2.20} source.f: user-written source | FLUKA, bottom half of the page)

However, since you are planning to generate the input file, it would be much easier to implement the sampling directly inside the source routine.

Cheers,
David
