Now Live: Showcase for Electrical Engineering
Alexandra Foley August 11, 2014
Interested in using COMSOL Multiphysics to simulate electrical applications? The new Electrical showcase is a resource for those of you who want to learn about the COMSOL software’s capabilities for modeling a variety of electrical systems, components, and devices. The showcase provides you with valuable content such as how-to videos, user case studies, white papers, and example models specific to your area of expertise.
Designing and Modeling Electrical Systems and Devices
The Electrical showcase, called Designing and Modeling Electrical Systems and Devices, is a resource created by COMSOL applications engineers and developers alike to demonstrate the modeling capabilities of COMSOL Multiphysics in a comprehensive and resource-oriented guide.
In the showcase, you’ll find information about the six modules offered by COMSOL specifically designed for simulating such diverse applications as transformers, electronic packaging, the propagation of waves in and around structures, analyzing microwave devices and antennas, and much more. The showcase introduces the philosophy of the COMSOL software by demonstrating the various ways in which you can use it to perform detailed simulations with real-world accuracy. The showcase is divided into sections to display this functionality most effectively; you’ll find sections on Joule and Induction Heating, Optics and Photonics, and Plasma physics, just to name a few. Explore these and other areas by selecting from the available categories.
The Multiphysics Approach to Modeling
When exploring the showcase, and the COMSOL Product Suite in general, the philosophy of the multiphysics approach to modeling will become apparent. We developed the Product Suite to allow you to conduct fully-coupled analyses of applications involving multiple physics in one and the same simulation environment. For electrical engineers, an example of this modeling approach is the design of a power transmission line, where heat transfer, structural mechanics, and electromagnetics all come into play.
Electrical Engineering Example: Power Transmission Line
In a power transmission line, operating temperatures can affect load-carrying capabilities and even the protective coating that surrounds electrical cables. As a result of the heat produced as current flows through the conductor, the system temperature rises and the electrical and thermal material properties of the conductor change. The interaction between these physics can change their expected behavior, altering, for example, the current-carrying capabilities of the conductor as well as the durability of the cable’s protective coating.
In this application, the electrical and thermal effects are interdependent and strongly coupled. Therefore, the simulation must couple the physics the same way they are in the real world. The objective is to find a self-consistent solution that satisfies all physics. This is the key strength of COMSOL Multiphysics, where accurate analyses are accomplished through the use of a truly multiphysics code that allows engineers to apply an unlimited number of physics analyses in a single simulation.
The Designing and Modeling Electrical Systems and Devices resource shows you more about this approach to multiphysics modeling and how you can employ it in your own simulations.
Learn More by Contacting COMSOL Experts
Once you have finished exploring the different application areas, you can contact COMSOL experts to ask any additional questions you might have. A short form is provided at the end of the showcase that will put you directly in contact with our application engineers.
