This module is new in version 4.2a. The Particle Tracing Module
is a general purpose, flexible tool that allows you to trace the
trajectories of particles in the presence of an external field.
The Particle Tracing Module includes the following physics
interfaces: - Mathematical Particle Tracing: - Specify the
equations of motion using massless, Newtonian, Lagrangian, or
Hamiltonian formulations. - Complete freedom over the equations
makes it possible to model ray tracing, for example. - Charged
Particle Tracing - Use this interface to model ion and electron
trajectories in electric and magnetic fields - This interface
make it easy to define electric, magnetic, and collisional
forces - Particle Tracing for Fluid Flow - Use this interface to
model microscopic and macroscopic particles in a fluid -
Includes drag, gravitational, dielectrophoretic,
acoustophoretic, and many other forces. For visualization of the
results two new plot types are available: - Poincaré Map: You
can use a Poincaré Map plot for 2D and 3D
