I am implementing a mechanism to enforce a cap on particle velocities so that particles cannot move more than one subdomain per time step. The ultimate goal is to completely eliminate global communication from the particle solver. While this does violate the mathematical formulation of the method, such very fast particles should be extremely rare and are not expected to be well resolved by the method anyway.
