Designing Spiral Slot Antennas with Electromagnetics Simulation

February 21, 2018

Spiral slot antennas have nearly perfect circularly polarized radiation and wideband frequency response, and they can maintain a consistent radiation pattern and impedance over large bandwidths.

Analyzing Vehicle Suspension with Multibody Dynamics Modeling

February 20, 2018

How much damage can a pothole do to a car? Automotive engineers can set up lumped mechanical systems in COMSOL Multiphysics® to analyze vehicle suspension technology.

Happy Birthday, Alessandro Volta

February 18, 2018

Alessandro Volta started out by studying how static electricity generates a physical response in frog legs. The unit of electric potential and electromotive force, the “volt”, is his namesake.

Optimizing the Interference Fit Between 2 Pipes with Structural Analyses

February 15, 2018

The interference fit between 2 pipes can’t be too tight or too loose. Like the porridge in the “Goldilocks and the Three Bears” story, it has to be just right.

How to Model Roller Bearings in COMSOL Multiphysics®

February 14, 2018

Roller bearings are one of the most commonly used industrial components, found in gearboxes, conveyors, motors, and rolling mills, among other devices. Learn how to model this part in COMSOL®.

Analyzing the Deformation of a Biomedical Stent with Simulation

February 13, 2018

By studying deformation in an arterial stent, biomedical engineers can account for unwanted effects like dogboning and foreshortening long before the device is ever implanted.

Modeling the Flow of Ice in COMSOL Multiphysics®

February 8, 2018

The dynamics of glaciers are a complex (and “cool”) subject to study. One method is by using fluid flow simulation to analyze the flow of ice, from accumulation to ablation.

Simulating Natural Convection in Air with COMSOL Multiphysics®

February 7, 2018

From small electronic components to large buildings, natural convection is a transport phenomena found in engineering disciplines of all sizes. Here’s an example of natural convection in air.
