Training Course: Modeling Plasma in COMSOL Multiphysics^®

If you are a new or experienced user of COMSOL Multiphysics^® who wants to learn about modeling plasma, this online training course is for you. Join our 5-day program to deepen your understanding of the Plasma Module, an add-on to the COMSOL Multiphysics^® software.

The course will begin at an introductory level, with discussion of how to build and mesh geometry in COMSOL Multiphysics^®. We will then present the specialized features for modeling low-temperature and thermal plasmas, focusing on various study types, interfaces, and their settings. Next, we will demonstrate the use of the Inductively Coupled Plasma and Microwave Plasma interfaces. We will conclude with an overview of how plasma physics can be coupled with fluid flow and heat transfer.
