Application-Specific: Polar, Far-Field, and Particle Tracing Plots
When postprocessing your electromagnetics models, you can use polar, far-field, and particle tracing plots to effectively display your results. Learn how to use these 3 plot types here.
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.
