Modeling Waveguides that Support Multiple Modes
2 ways you can model a waveguide that supports multiple modes: add a PML that can be used to absorb any modes, or explicitly add ports for each possible mode.
Computational Electromagnetics Modeling: Which Module to Use?
If you work with a particular electromagnetic device or application area, you might be wondering which module in the COMSOL product suite is right for you. Keep reading for a comprehensive intro.
Video Lecture Series: Modeling Electromagnetic Coils in COMSOL®
Get an overview of our video lecture series on modeling coils using COMSOL Multiphysics and the AC/DC Module, from setting up a coil model to analyzing electromagnetic heating and more.
Exploiting Hardware Parallelism with COMSOL® Batch Sweeps
What is a batch sweep? How do I set up a batch sweep for my model? How much batch parallelism can COMSOL Multiphysics® exploit? We answer these questions and more…
How to Use State Variables in COMSOL Multiphysics®
As of COMSOL Multiphysics® version 5.5, you can use state variables to track the state of your model; affect other fields, such as material properties; and even implement hysteresis.
Modeling the Scattering of Light Off of an Object on a Substrate
A common modeling scenario in wave electromagnetics: computing the scattering of light off of a structure patterned on top of a uniform dielectric substrate.
Join Us for Tech Cafés at the COMSOL Conference 2020 Boston
We’re introducing Tech Cafés and updated minicourses at the COMSOL Conference 2020 Boston. Here’s why and what to expect.
Building a Magnetohydrodynamic Multiphysics Model in COMSOL®
Magnetohydrodynamic models call for fluid dynamics and electromagnetics couplings. To do so, you can set up bidirectional couplings between all physics equations or building a simplified model.
