How to Create Animations Along the Azimuthal Direction for 3D Models

June 4, 2018

Here’s a useful postprocessing trick for presenting your 3D modeling results: combine slice plots along the azimuthal direction in order to generate a nontrivial animation.

Terminal Velocity, Drag Coefficients, and FIFA World Cup™ Predictions

June 1, 2018

Is it possible to predict the winners of the FIFA World Cup™? We forgo consulting a psychic and instead analyze the terminal velocity and drag coefficients of different balls with CFD simulation.

Modeling Free Surfaces in COMSOL Multiphysics® with Moving Mesh

May 31, 2018

You can model free liquid surfaces that do not undergo topology changes using moving mesh functionality in the COMSOL® software. Here’s a thorough guide on how to do so.

Studying the Van Allen Belts with Particle Tracing Simulation

May 30, 2018

Get a closer view of the Van Allen belts, 2 doughnut-shaped belts of radiation that surround Earth, with the help of particle tracing software.

What Is the Doppler Effect?

May 29, 2018

A siren passes by and you hear a change in pitch. A bug swims across a puddle, causing ripples on the surface. A star in the sky has a reddish hue. These are all examples of the Doppler effect.

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.

Analyzing the Current Distribution in a Lead-Acid Battery Design

May 24, 2018

The lead-acid battery in your car is not much different from the original one developed by Gaston Planté in 1859. 1 change is that you can now analyze the current distribution using simulation.
