Do Bumblebees Use Their Hairs or Antennae for Electroreception?
A research team at the University of Bristol combined the power of physical experiments and simulation to study how exactly bumblebees use electroreception.
How to Analyze an Induction Motor: A TEAM Benchmark Model
In this blog post, we demonstrate the modeling of the three-phase induction motor described in Testing Electromagnetic Analysis Methods (TEAM) workshop problem 30a.
How to Dynamically Modify Geometries in Simulation Apps
We demonstrate how to use the Method Editor to create an app for: 1.) dynamically creating and modifying geometry parts and 2.) applying appropriate physical specifications and mesh.
How to Model Solar Concentrators with the Ray Optics Module
Learn how to predict the concentration ratio for an idealized, parabolic solar reflector using Monte Carlo ray tracing in the Ray Optics Module, an add-on to COMSOL Multiphysics®.
Using the New Ray Tracing Algorithm in COMSOL Multiphysics® 5.2a
The ability to trace rays in unmeshed domains, and even release and trace rays outside a geometry, has been available in the Ray Optics Module as of COMSOL Multiphysics® version 5.2a. Learn more.
AltaSim Uses Simulation to Improve Bolometer Sensitivity
Bolometers can be used to detect and measure the power of incident electromagnetic radiation. To efficiently design bolometers with increased sensitivity, AltaSim Technologies used simulation.
