I am wondering if anyone has any experience with or has any idea how to add an energy loss term within a particular volume. My application is that I want to track electrons in a magnetic field where, upon entrance to a specified volume, the electrons lose energy due to interaction with the material.

The energy loss takes the simple form of dE/dx*s where the dE/dx is the energy loss per unit length and s is the path length. I can foresee that the velocity magnitude would need to be reduced after each tracking step based on the step size thereby reducing the Larmor radius as the electron penetrates the material.

I am not certain how to implement this in COMSOL.
