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)!
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.
Designing District Heating Networks Using Topology Optimization
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®
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.
