Happy Birthday, Nicolaus Copernicus
Polish astronomer Nicolaus Copernicus first theorized the concept of a heliocentric universe. At the time, this was controversial. Now, more than 500 years later, we believe him.
Piezoelectric Materials: Crystal Orientation and Poling Direction

Which Current Distribution Interface Do I Use?
See the different current distributions with a wire electrode example to help you choose between the current distribution interfaces in COMSOL Multiphysics® for your electrochemical simulations.
Intro to the What, Why, and How of Shared Memory Computing
A couple of weeks ago, we published the first blog post in a Hybrid Modeling series, about hybrid parallel computing and how it helps COMSOL Multiphysics model faster. Today, we are going to briefly discuss one of the building blocks that make up the hybrid version, namely shared memory computing. Before that, we need to consider what it means that an “application is running in parallel”. You will also learn when and how to use shared memory with COMSOL.
Improving Bioreactor Performance with COMSOL Multiphysics
A guest blogger from Continuum Blue gives an overview of what the consultancy can do using simulation for their biomedical engineering clients.
New Technology Advancements for Indoor Navigation
Global position systems, more commonly known as GPS, make it easy to navigate from place to place. But what about navigating inside an actual building? Indoor navigation makes this possible.
The Linac-MR Project: Tumor Tracking and Treatment
Not too long ago, my colleague Jennifer wrote a blog post about the Cross Cancer Institute, and the research being conducted there into the design of a new device for treating cancerous tumors. The device, known as the Linac-MR, is revolutionary due to its ability to both image and treat cancer cells simultaneously — a capability that had previously been regarded as near impossible due to the conflicting physics interactions involved. Such a device would allow for extremely precise radiation […]
Using Adaptive Meshing for Local Solution Improvement
One of the perennial questions in finite element modeling is how to choose a mesh. We want a fine enough mesh to give accurate answers, but not too fine, as that would lead to an impractical solution time. As we’ve discussed previously, adaptive mesh refinement lets the software improve the mesh, and by default it will minimize the overall error in the model. However, we often are only interested in accurate results over some subset of the entire model space. […]
