February 16, 2015

Interested in modeling periodic, or pulsed, heat loads? Modeling such a situation accurately and efficiently in COMSOL Multiphysics® is simple with the Events interface. Learn more…

Discretizing the Weak Form Equations

February 9, 2015

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.

Application-Specific: Polar, Far-Field, and Particle Tracing Plots

February 2, 2015

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.

Using Perfectly Matched Layers and Scattering Boundary Conditions for Wave Electromagnetics Problems

January 28, 2015

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.

Dielectrophoretic Separation

January 23, 2015

Dielectrophoresis is a phenomenon in which an electric field is used to control the movement of electrically neutral particles. Learn about how to model this effect in both DC and AC fields.

How to Use COMSOL Multiphysics, a Tutorial Video

January 16, 2015
