Micromagnetic Simulation with COMSOL Multiphysics®

September 24, 2021

A guest blogger from Fudan University in China used the Physics Builder in COMSOL Multiphysics to create a “Micromagnetics Module” for performing micromagnetic simulations.

3 Examples of Optimizing Loudspeaker Components

June 3, 2021

Whether in a home theater system, gym, or massive concert venue, loudspeakers need to perform optimally. 1 way to do so is by performing a shape or topology optimization study of its components.

Simulating Wind Load on a Sports Car’s Side Door and Mirror

May 27, 2021

Vroom vroom: In this blog post, we use large eddy simulation (LES) and structural analysis to analyze wind loads and airflow on the door and side mirror of a sports car driving at high speeds.

Building a Solid Foundation for Understanding Seismic Waves

April 22, 2021

In 1906, there was the California earthquake. In 1908, there was the Lawson Report. In 1910, Harry Fielding Reid proposed the elastic rebound theory. Continue on a deep dive into seismology…
