<div style="RIGHT: auto">I have been stydying the par files that are provided, but can't seem to figure out how to add an external scalar, spinor, or vector field to the simulation. Specifically, I am interested in periodically sweeping a polarized electromagnetic plane wave across a simulation volume, from a source point that is outside the simulation volume. I am also curious about permeating a volume with a bispinor field. Is there a package that I would have to add?</div>
