Modeling a Rapid Detection Test in COMSOL Multiphysics®

April 21, 2021

Curious about how exactly the rapid detection tests for COVID-19 work? Get a comprehensive explanation here, as well as 3 example models in COMSOL Multiphysics®. (Part 2 of 2)

An Introduction to the Physics of Rapid Detection Tests

April 20, 2021

Rapid detection tests based on lateral flow assay (LFA), also called immunochromatographic tests, can be thought of as quite advanced, yet very robust, microlaboratories. (Part 1 of 2)

Analyzing Tsunami Waves with an Established Benchmark Model

April 8, 2021

The 1993 Hokkaidō earthquake in Japan caused tsunami waves that reached massive runup heights — one recorded wave in Monai Valley even reached as high as 32 m (~104 ft)!

Modeling the Behavior of an Oldroyd-B Polymer

April 1, 2021

Have you ever noticed that when a certain force is applied to a viscoelastic fluid, the fluid starts to look like beads on a string? Here, we showcase an example that uses an Oldroyd-B polymer.

Designing District Heating Networks Using Topology Optimization

February 8, 2021

District heating networks help power plants reach high efficiencies by utilizing cogeneration, which is especially helpful in the winter. How does topology optimization fit in? Keep reading…

Modeling Droplet Flow in an Open Space with COMSOL Multiphysics®

November 23, 2020

If you are jogging six feet apart from someone else, should you both be wearing masks? Simulation was used to analyze the motion of particles between two runners in an open space to find answers.

How Does This Lip Gloss Appear to Defy Gravity?

September 10, 2020

We attempt to explain a mysterious, gravity-defying phenomenon involving a viral video, dielectric materials, electrostatics, and lip gloss.

Optimizing an NIV Mask Design with Multiphysics Simulation

August 13, 2020

NIV masks offer a form of noninvasive monitoring and ventilation for COVID-19 patients, which lessens the need for ventilators and other mechanical respirators.
