Charged Particle Tracing Equations

Is there a way that I can change the underlying equations for the Charged Particle Tracing Module? I have a constant electric field created, but instead of the particles passing through it feeling a force (and therefore accelerating) F= qE, I want to make it so that the particles' drift velocity is proportional to the electric field, v = cE.

Thanks!

So your particles are effectively massless, is that it? That is, you're not interested in how they acquire that velocity, just that they get up to speed in virtually no time. If so, you can set that property in the particle tracing module's top node (change "Formulation" from "Newtonian" to "Massless") and then enter the expression for their velocity in the "Particle Properties" subnode.
