Understanding MCNP Tally F5 Output: Tips for Beginners

[Sonong]

I am beginner in MCNP. Could someone please show me how to read the output file when using Tally F5. I saw that the result involves collided and uncollided photon flux, so which part needs to be chosen for calculating? Thank you.

Welcome to physicsforums!

If you are using an input file written by an expert that you can share you should rename it to add .txt and attach it to the thread. If you wrote it yourself and chose an F5 over another tally I would ask why?

For a real world problem you would calculate using collided and uncollided flux unless you know you want something different. Real world experiments can't tell one from the other, that is only possible in a simulation.
