Dear Kevin,
You are right : the usual way of doing that is to call MGDRAW with Userdump. You could even use the version of the mgdraw given in the distribution, it will yield among others the information you seek. However, not only will it give to you lots of information about the whole history that you might not need, it will also give it unformatted. What could be better for you is to have a look at the Mgdraw routine, locate the place where all the printouts are and comment them out, replacing them with a write command dumping as text in any unit specifically the info you seek (for example x, y, z for tracking the path).
Try that and if you need any further help in modifying the routine, I'll be happy to assist
Cheers
Philippe

Subject: [fluka-discuss]: Attempts to track particles using USERDUMP
Dear FLUKA experts,
I am a new user of both FLUKA and FLAIR, and am currently teaching myself how they work. I have a very specific problem that I am attempting to use FLUKA for, and am currently having some difficulty understanding how to best go about it. The basis of the problem is tracking neutrons (the particles being introduced by me to the system) as they interact in a medium (in the preliminary case, pure ice). I am only really interested in the position and trajectory of the neutrons that I introduce, and have little to no concern for any other particles. The end result would be a complete path of the neutrons travelling throughout the ice until they are ultimately captured by some atom.
From the last few days of reading and researching through the guides and manual, I believe the solution lies somewhere in the realm of USERDUMP and the mgdraw user routine. I am also fairly certain that I will be unable to simply use the regular input cards provided by FLUKA.Before I go in depth in attempting to use mgdraw, I would like to have a better understanding of what I should be modifying to avoid the information overload warnings that I have read about.
I know this may be a very simple question, but I would greatly appreciate any assistance with it.
Regards,
Kevin Crust
