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.

Computing Loss, Temperature, and Efficiency in Electric Motors

September 23, 2021

Follow along as we investigate the variation of iron and copper losses, the resulting temperature rise, and its effect on the efficiency of a permanent magnet machine.

Wrapping and Warping Geometries for Analysis in COMSOL®

September 10, 2021

CAD parts are typically designed in an undeformed, as-manufactured state. When it comes to analysis, however, we are only interested in the deformed, as-assembled state.

Zooming in on a Compact Camera Module Design with Simulation

July 20, 2021

Lights, camera, simulation: Read about factors that help define the performance of compact camera modules (CCMs) as well as how optical ray tracing can be used to analyze their design.

Designing Antireflecting Microstructures for Infrared Applications

June 29, 2021

Explore how 2 microstructure designs can improve the bulk transmittance of silicon (~70%) and cadmium zinc telluride (~79%) to more than 90% within the specific wavelength spectrum.

Voltage and Ground When Modeling Wave-Like EM Fields

June 17, 2021

We continue our discussion of voltage and ground by defining and interpreting these terms for sinusoidally time-varying electromagnetics models.

Do Voltage and Ground Exist?

June 15, 2021

Remember how the terms “voltage” and “ground” were taught in your university electrical engineering classes? Get a precise definition (in terms of modeling computational EM problems) here.
