Online Training: AC/DC Modeling (4 Days)

June 15–18, 2021 10:00 a.m. EDT

Back to Events Calendar

Join us for an intensive introduction to using COMSOL Multiphysics® for modeling electromagnetic phenomena and devices in this online training course. Through 4 days of training, you will develop a strong foundation for your future electromagnetics and related multiphysics modeling needs.

The course starts at an introductory level, leading attendees through the essential steps needed in low-frequency electromagnetic simulations using COMSOL Multiphysics®. You will learn how to model devices such as inductors, capacitors, transformers, and motors. You shall be empowered to perform coupled FEM–circuit simulations, extraction of lumped parameters, electromagnetic heating, and other multiphysics analysis and use postprocessing to assess the performance of electromagnetic devices.

To teach this course, we use a combination of presentations, model demonstrations, guided hands-on training, self-guided exercises, and Q&A sessions. The goal is to immerse you in all of the main aspects of using COMSOL Multiphysics® and the relevant add-on modules so that you feel comfortable working with the software. By the end of the 4-day training course, you will know how to set up an electromagnetic model, choose the right boundary conditions, select appropriate mesh settings, and use the postprocessing for visualization and getting useful insights.
