Computing Total Normal Flux on a Planar Surface

June 9, 2014

1 way to bridge the gap between simulation and experiment? Compute the total normal flux through a cross-sectional plane passing through your simulation geometry. Here’s how >>

Understanding Stabilization Methods

May 30, 2014

When modeling transport applications driven by convection, you need a stabilization method — whether you’re working with finite elements, finite volumes, or finite differences.

How to Include Geometry Surfaces with Solution Plots

May 26, 2014

You’ve solved your model. Now you want to include geometry surfaces with your solution plots. But how? We demonstrate the steps with an RF antenna example.

Intro to Corrosion Modeling for the Oil and Gas Industry

May 22, 2014

From impressed cathodic current and anodic protection to sacrificial anodes, there are several ways you can protect structures from corrosion. We discuss some modeling considerations here.

Quick Intro to Modeling RF and Microwave Heating

May 20, 2014

If you’ve attended a COMSOL webinar about an RF topic, you’ve probably seen our model of a waveguide with a bend. That’s because it illustrates microwave heating in an easy-to-understand way.

Intro Model: Studying the Signal Strength of RF Coils

May 9, 2014

Electronics designers need to ensure that RF coils contained within their devices can properly transmit information from a source to its destination. Electromagnetics simulation can help.

How to Integrate Functions Without Knowing the Limits of the Integral

April 30, 2014

Did you know that the COMSOL® software can solve integrals as well as partial differential equations? Learn how to integrate functions — even without knowing the limits of the integral.

The Strength of the Weak Form

April 29, 2014

Learn about the origins of the weak form equations, how to derive them from classic equations, how to express them in the COMSOL Multiphysics® syntax, and more >>
