Exploiting Hardware Parallelism with COMSOL® Batch Sweeps

June 2, 2020

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®

May 20, 2020

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

April 14, 2020

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®

June 19, 2019

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.

Using Discontinuous Meshes for Conjugate Heat Transfer Modeling

November 21, 2018

You can use different discontinuous meshes in neighboring domains in COMSOL Multiphysics®. This capability comes in handy, particularly when modeling conjugate heat transfer problems.

3 Approaches to Modeling Moving Loads and Constraints in COMSOL®

October 22, 2018

Learn 3 ways to model moving loads and constraints in COMSOL Multiphysics®: using variables, interpolation functions, and paths imported from CAD geometries.

How to Model Conductors in Time-Varying Magnetic Fields

May 25, 2018

You can use the AC/DC Module to perform frequency-domain simulations for conductors in time-varying magnetic fields by describing the skin effect.
