How to Model Rotating Machinery in 3D
There are many different types of electrical machines, but rotating machines like generators and motors play a major role in our modern industrial society. Learn how to model these systems in 3D.

Using Deformations to Visualize Physical Motion
Postprocessing and visualization can help enhance your understanding of simulation results, and using plots to illustrate physical motion allows you to put everything into perspective.

Do Hybrid and Electric Vehicles Have the Pulling Power?
Designers of hybrid and electric vehicles need to have a good understanding of how the car’s lithium-ion battery operates to ensure both performance and safety.

Implementing the Weak Form with a COMSOL App
First we implement the weak form equation and examine its matrices. Then we create a simulation app that displays all relevant matrices at once, arranged logically on one screen.

Which Module Should I Choose for Working with My CAD Data?
We go over which add-on module or LiveLink™ interfacing product is best for your modeling scenarios involving CAD data. Get a comprehensive overview here.

Modeling Laser-Material Interactions with the Beer-Lambert Law
Did you know that you can use the Beer–Lambert law to model laser–material interactions in COMSOL Multiphysics®? Learn how here.

How Can I Build an Efficient Stirling Heat Pump?
Did you know that heat pumps are also called Stirling engines? These systems can operate on incredibly low temperature differences — some only need human body heat to work!

Using the Boussinesq Approximation for Natural Convection
Today, we compare the Boussinesq approximation to the full Navier-Stokes equations for a natural convection problem. We also show you how to implement the Boussinesq approximation in COMSOL Multiphysics software and discuss potential benefits of doing so.

Can We Hear the Shape of a Drum?
Over half a century ago, Mark Kac gave an interesting lecture on a question that he had heard from Professor Bochner ten years earlier: “Can one hear the shape of a drum?”

Improving Your Meshing with Partitioning
It can be tedious to subdivide your CAD geometry into a finite element mesh. In this blog post, we demonstrate how to use a manual meshing method called geometric partitioning to do so.

Curve Fitting of Experimental Data with COMSOL Multiphysics
Have you ever had to work with experimental data in a model? Learn how to fit smooth curves and surfaces to experimental data using the core functionality of COMSOL Multiphysics®.

Modeling Current Distributions in a Molten Salt Electro-Refiner
A guest blogger from SIMTEC discusses how he uses simulation to analyze current distributions in a molten salt electrorefiner. Get details here >>
