The Charged Particle Tracing Interface (
 ): Use it to model charged particle orbits under the influence of electromagnetic forces. In addition, it can also model two-way coupling between the particles and fields. Some typical applications are particle accelerators, vacuum tubes and ion implanters. The physics interface supports time-domain modeling only in 2D and 3D. The interface solves the equation of motion for charged particles subjected to electromagnetic forces. |

The Particle Field Interaction, Non-Relativistic Interface (
 ): Combines the Charged Particle Tracing interface with the Electrostatics interface. The Electric Particle Field Interaction multiphysics coupling feature is added automatically. The Particle Field Interaction, Non-Relativistic interface is used to model beams of charged particles at non-relativistic speeds. The particles generate a space charge density term as they propagate through domains. The space charge density is then used as a source term in the Electrostatics interface, and the resulting electric force on the particles is computed. |

The Particle Field Interaction, Relativistic Interface (
 ): Combines the Charged Particle Tracing, Electrostatics, and Magnetic Fields physics interfaces. The Electric Particle Field Interaction and Magnetic Particle Field Interaction multiphysics coupling features are added automatically. The Particle Field Interaction, Relativistic interface is used to model beams of relativistic charged particles. The particles generate space charge density and current density terms as they propagate through domains. The space charge density and current density are then used to compute electric and magnetic forces, respectively, which are exerted on the particles. |
