Discretizing the Weak Form Equations
In another installment of our blog series on the weak form equations, get an overview of how these equations are discretized and solved numerically in the COMSOL® software.
Why Car Batteries Perform Poorly in Cold Weather
Have you ever gone to start your car on a cold winter morning and nothing happens? The battery’s ability to convert chemical energy into electrical energy can be affected by low temperatures.
Predicting Cavitation in Journal Bearings
When designing journal bearings for use in a rotating shaft, the effect of cavitation needs to be considered, because it can affect the performance of these components.
How to Compute the Acoustic Radiation Force
Did you know that objects can actually be moved by sound? This effect is called acoustic radiation, and it is an acoustophoretic phenomenon that can be analyzed in the COMSOL® software.
Using Perfectly Matched Layers and Scattering Boundary Conditions for Wave Electromagnetics Problems
Learn how to use scattering boundary conditions and perfectly matched layers to truncate domains for your wave electromagnetics problem — and which technique is best for your modeling scenario.
Cloaking Advancements for Flexural Waves in Elastic Plates
A European research group discovered a theoretical framework to both overcome the limitations of cloaking and achieve exact cloaking for flexural waves in Kirchhoff–Love plates. Get details >>
From Books to Technology: Pop-Up Fabrication Techniques
Fabricated “pop up” books aren’t just for kids: Researchers are using the same fabrication techniques to turn 2D micro- and nanostructures into extended 3D layouts.
