Particle Tracing in Electric and Magnetic Fields

Particle tracing modeling and simulation are crucial for accurately predicting the motion of ions or electrons in electric or magnetic fields. Even the smallest leakage current can result in a particle that can damage a chip. Such leakage currents can arise from phenomena such as cold field emission or Townsend discharges. Particle tracing can be used to model these effects, leading to a deeper understanding and the optimization of the process.

The Particle Tracing Module is equipped with specialized functionality for these types of models. The software offers various predefined forces that affect the motion of particles, such as electric, magnetic, gravitational, and collisional forces. Additionally, users can incorporate custom-defined expressions to account for the particles' interactions with other fields. Furthermore, the software contains unique functionality for using bidirectional couplings between fields and particles, specifically for situations where particles impact electromagnetic fields.

Introduction to Simulation Apps

Modeling and simulation are no longer limited to the expertise of a few individuals within an organization. The availability of simulation tools throughout the product or process design workflow — from R&D to the factory floor — allows for a more collaborative and innovative approach to problem-solving. Now, even those without prior modeling knowledge can contribute to the process, leveraging the expertise of modeling experts.

To facilitate this collaboration, the Application Builder in COMSOL Multiphysics® allows modeling experts to create custom apps with user-friendly interfaces that can be used by scientists and engineers without modeling experience. These simulation apps serve to simplify the modeling process and extend the functionality of simulations to more users, regardless of their skill level.

By using the Application Builder together with the COMSOL Multiphysics® platform's built-in Model Builder and Model Manager tools, engineering organizations can establish an efficient, collaborative, simulation-based environment to foster innovation.

In this session, you will learn how to use the Application Builder to create simulation apps and how to distribute them for use by others.
