Question How to not track particles below a specified energy or of a specified particle species 

Forum: Fast Simulation, Transportation & Others
Date: 19 Jan, 2017
From: <adamrouh>

I need to know a way to have my simulation not track particles below some energy threshold. I am using the physics in example Hadr03, and elastic collisions of a neutron creates many protons, and these protons are transported by a few angstroms, as shown in the attachment. I do not care about these protons and would like to somehow ignore them for computational efficiency purposes only.

I would also like to somehow ignore particles of some specified species. Sometimes a neutron at a high enough energy will produce photons somewhere in my simulation. I do not care about these photons and would like to somehow ignore them as well.
