Simulating Permanent Magnet Generators

November 6, 2012

Permanent magnet generators, or PM generators as they are also called, generate power without batteries. PM generators consist of a magnetic stator coiled with wire and a wheel with permanent magnets rotating inside the stator. From motorcycles to wind farms, PM generators can be used in many electrical machinery applications. Let’s take a look at how these types of generators work and how they can be simulated.

Impedance Boundary Conditions Help in Modeling Non-Destructive Testing (NDT)

July 23, 2012

How do you simplify a 3D geometry to reduce the computational resources required to model it? Do it in 2D. What if the phenomenon can only be properly simulated in 3D? Find the planes of symmetry and reduce the size, most engineering objects are symmetric in some way. What if there is no symmetry, such as the propagation of random cracks through a steel pipe? Well, as this story from COMSOL News shows, there are other methods, such as using […]

Investigating the Fundamentals of an “Old” Technology

July 13, 2012

Transformers were first commercially used in the late 1800’s, but they are still being investigated at their fundamental levels. One of the stories from our latest COMSOL News concerns ABB (who themselves have been around since the late 1800’s) and their research into these apparatuses.

Now There’s Thermal Cloaking

March 27, 2012

As an avid reader of the physorg.com blog, I was pleasantly surprised to see a figure show up that could only have been made with COMSOL Multiphysics. Reading the article on thermal cloaking, I understood why.

What Is the Nature of Pain?

March 26, 2012

A second user story for the next COMSOL News is also reaching completion with exciting results (read about the first one here). This is an interesting case as it wasn’t really a group of people traditionally associated with finite element that managed to perform some pretty sophisticated modeling. In fact two of them are medical doctors while the final one has his background in physics.
