CAD: COMSOL - Particle Tracing Module
Minimum Subscription Required:
The Particle Tracing Module extends the functionality of the COMSOL environment for computing the trajectory of particles in a fluid or electromagnetic field, including particle-particle, fluid-particle, and particle-field interactions. It 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 visulatization of the results, two new plot types are available:
- Poincare Map: You can use a Poincare Map plot for 2D and 3D models to visualize particle trajectories in a section that is transversal to the particle trajectories.
- Phase Portrait: You can use a Phase Portrait plot for 2D models to visulalize large data sets of particle trajectories. A phase portriat is a geometric representation of the particle trajectories in the phase plane.
All of the interfaces provide many different ways of releasing particles, either on the boundary or domain level. Particles can also be released at multiple deifferent times. There are several options available for describing how the particles interact with the wall, including specular reflection. The interfaces can all be used with COMSOL Mulitphysics but tracing charged particles benefits from the AC/DC Module because it makes it possible to model complex alternating or direct current systems. Similarily, tracing particles ina fluid system benefits from the CFD Module or the Microfluidics Module due to the number of advanced fluid flow features available in those modules.
