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.
Why Do Pigeons Have Iridescent Feathers?
If you look at a pigeon a certain way, the feathers around their necks shine in bright hues of emerald and amethyst. As it turns out, a prehistoric animal exhibited a similar trait…
6 Examples of Simulation-Driven Loudspeaker Development
From headphones for virtual reality gaming to powerful transducers for hearing aids, here are 6 examples of multiphysics simulation being used to develop new and improved loudspeaker products.
Add a Full State-Space Feedback Controller to a Control System Model
Get a brief overview of full state feedback, learn how to use the State-Space Controller add-in, and get a demonstration of implementing the add-in using a mass-spring-damper system example.
Happy Birthday, Joseph Fourier
From heat conduction and the Fourier series to the greenhouse effect and Fourier transform, Joseph Fourier’s research has many implications in the modern world.
Combining Adaptive Mesh Refinement with Data Filtering
In a follow-up to our previous blog post on data filtering, we demonstrate how to implement adaptive mesh refinement and a Helmholtz filter for a thermal model with a nonuniform heat load.
Using Data Filtering to Improve Model Performance
Want to include experimental data in your model as a load or boundary condition, but the data varies over space or time and is noisy? Try implementing data filtering, such as a Helmholtz filter.
How to Model a Hall Effect Sensor with COMSOL Multiphysics®
Basic working principle of a Hall effect sensor: A nearby magnetic field deflects the path of current through a semiconductive sensor, which causes a measurable change in potential.
