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.

Analyzing Multiphase Flow in an Airlift Loop Reactor Benchmark Model
