Modeling the Pulsed Laser Heating of Semitransparent Materials

January 3, 2023

Laser light is often used to rapidly heat materials within the semiconductor processing industry. Here, we explore this method with heat transfer simulation.

Intro to Modeling Transient Heating of Solids in COMSOL Multiphysics®

December 12, 2022

Transient heat transfer models are easy to set up and solve, but the interpretation of their results can lead to confusion. Here, we explore this scenario with a simple heat transfer model.

Computing Orbital Heat Loads with COMSOL Multiphysics®

November 23, 2022

As of version 6.1, the Heat Transfer Module includes a new interface for defining satellite orbit and orientation, orbital maneuvers, and varying planetary properties.

Losses in Three-Phase Transmission Lines

July 26, 2022

Explore how to model the losses in three copper wires in a linear and an equilateral arrangement.

How Large of a Model Can You Solve with COMSOL®?

May 6, 2022

Ever wonder how large of a model you can solve in COMSOL Multiphysics®? It depends on memory requirements, model size, and the dimension of your finite element problem.

Computing and Visualizing Satellite Orbits in COMSOL®

March 9, 2022

Here, we introduce a new, out-of-this-world tutorial model of a spacecraft in orbit.

Computing and Using Partial Inductance with COMSOL®

March 3, 2022

COMSOL Multiphysics® version 6.0 brings new functionality for computing total and partial inductances and AC resistances. Get an overview here.

Creating Schlieren-Type Visualizations in COMSOL Multiphysics®

February 17, 2022

Did you know that Schlieren imaging might predate written history? Here, we explore this ancient imaging technique with CFD modeling.
