New Method for Performing Topology Optimization of FSI Problems
Many topology optimization methods are only available for FSI problems within a purely academic scope. Enter the TOBS-GT algorithm for fluid-structure design…
The Beauty of Vortex Streets
Vortex streets occur quite frequently in nature and are relevant in a variety of technical applications. This fluid mechanics phenomenon can also be quite beautiful to watch!
Modeling a Rapid Detection Test in COMSOL Multiphysics®
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
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
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)!
The Science Behind Cooking Caramel
Whether you’re adding it to brownies, crème brûlée, or an ice cream sundae, cooking caramel is a precarious task: One wrong move and it could burn and taste bitter or recrystallize and harden.
Modeling the Behavior of an Oldroyd-B Polymer
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.
Which Radiation Interface Should I Use for My Heat Transfer Model?
Compared to the mechanisms of heat transfer by conduction and convection, heat transfer by radiation has unique characteristics. How should you account for radiation in your heat transfer models?
