Modeling Metallic Objects in Wave Electromagnetics Problems

May 14, 2015

What is a metal, anyway? These materials are highly conductive and very good at reflecting incident electromagnetic waves, including light, microwaves, and radio waves.

Which Module Should I Choose for Working with My CAD Data?

April 14, 2015

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

April 13, 2015

Did you know that you can use the Beer–Lambert law to model laser–material interactions in COMSOL Multiphysics®? Learn how here.

Improving Your Meshing with Partitioning

March 27, 2015

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

March 19, 2015

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®.

Ports and Lumped Ports for Wave Electromagnetics Problems

March 9, 2015

The Lumped Port boundary condition can be used to model boundaries through which a propagating electromagnetic wave will pass without reflection. Learn how to use this feature in your EM models.

Implementing a Thermostat with the Events Interface

February 19, 2015

Hot or cold? You can use the Events interface in COMSOL Multiphysics® to implement a basic on-off thermostat in your model for controlling a heat load. Get a demonstration of how to do so here.

Modeling a Periodic Heat Load

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…
