COMSOL Day: AC/DC
See what is possible with multiphysics simulation
Join us for this 1-day event to learn about how simulation can be used to develop your low-frequency electromagnetics applications. You will have the opportunity to meet with COMSOL technical staff and COMSOL users from industry where AC/DC phenomena is integral, such as for motors, generators, transformers, and small inductive devices. We will also discuss coil modeling, electromagnetic heating, rotating machinery, and electrical circuits.
We welcome both experienced COMSOL Multiphysics® users and those who are new to the COMSOL® software to attend COMSOL Day: AC/DC. The sessions will focus on modeling techniques, and you will learn about the software features and best practices for specific topics. In a panel discussion, COMSOL users from industry will provide perspective on the importance of simulation for their applications.

The AC/DC Module is designed for low-frequency electromagnetics modeling. As an introduction to COMSOL Multiphysics® and this type of modeling, this session will investigate the phenomena and demonstrate some of the key features and techniques included in the AC/DC Module, such as coil modeling, inductive heating, electric motors, electrical circuits, and the efficient modeling of thin layers.
Looking at industrial applications, coils (or inductors) are found everywhere. Examples include converters and motors, as well as smaller devices such as mobile phones and headphones. This session starts with an overview of the different coil types you can model in COMSOL Multiphysics® and works toward the most prominent industrial application — the transformer. In the second part, we will cover multiphysics simulations and how they can help you predict the actual performance of your transformer.
Whether you want to protect your sensitive electronics from interference or reduce high-voltage fields around your power station, you need electromagnetic shielding. The AC/DC Module comes with a variety of boundary conditions useful for modeling the thin geometries that are involved. In this session, we will cover dielectric and magnetic shielding with linear and nonlinear materials, and look at how you can model the shielding efficiency versus the frequency.
Industry organizations will showcase how they are using multiphysics simulation to improve products and solve problems.

Turn on a power switch and you inevitably get heating. Joule and induction heating are easily the most common multiphysics phenomena in low-frequency electromagnetics, and this session will show you how to model them. We will cover the basics, such as analyzing how conductive or induced currents create heat, as well as more complex applications, including heating a moving mechanical part or the effect of the Curie temperature.
Ferromagnetic materials are at the heart of motors, transformers, inductors, and many other electromagnetic devices. A challenge with simulating these applications and devices is to consider the variable and nonlinear properties of ferromagnetic materials, such as magnetic saturation, hysteresis, and anisotropy. Join us in this Tech Café to discuss and ask questions to COMSOL technical staff about techniques for modeling magnetic materials and phenomena, such as iron loss estimation, using Steinmetz or Bertotti loss models for fundamental frequency and harmonics, and explicit hysteresis modeling.
In this session, you will learn about using COMSOL Multiphysics® to model induction and permanent magnet electric motors. We will cover simulating the static, transient, and frequency-domain electromagnetic fields that arise around magnets and coils, which make up these motors, and further introduce various ways of modeling magnetically permeable materials. You will also see how the AC/DC-based physics in electric motors can be coupled to heat transfer to calculate cooling requirements, as well structural mechanics and acoustics behavior to predict noise.
Accurately calculating electromagnetic forces and torques is a key element in many electromagnetics-based models, for instance, in electric motor modeling. What techniques are available for calculating electromagnetic forces in the AC/DC Module? How can you estimate and improve the numerical accuracy of the calculated forces? This will be demonstrated and discussed during this Tech Café session.
Cable modeling is important for a wide range of applications in the power & energy industry. In recent years, dramatic improvements have been made in designing and optimizing these applications, through engineers simulating them with COMSOL Multiphysics®. Now, with the advent of the Application Builder, sophisticated cable models can be packaged into easy-to-use simulation apps, making the advantages brought by modeling accessible to all engineers and technical operatives in your organization.
To conclude COMSOL Day: AC/DC, this session will consist of live demonstrations and showcase examples from industry where HVDC applications have been simulated through models and with apps. We will discuss specific topics, such as twisted periodicity, magnetic armors, bonding types, dielectric loss, thermal effects, and more.
