Hi Richard, if you have separate studies for computing the magnetic fields and electric fields, then you just need to pass the solution from the magnetic fields study into the study computing the electric fields, then pass that solution into the study which computes the particle trajectories.
There is a Model Library example which demonstrates how to pass the solution from 2 prior studies into a third one. The model requires the AC/DC and Particle Tracing Modules.
