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.

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.
