Photos from the COMSOL Conference 2013 Bangalore
This year, over 260 multiphysics enthusiasts joined us for the COMSOL Conference 2013 Bangalore. While we did see some familiar faces, it was exciting to see plenty of new users at the event. We were able to capture some of the good moments on camera, and would like to share a selection of the photos with you here on the blog.
How to Identify and Resolve Singularities in the Model when Meshing
In our previous post on Meshing Considerations for Linear Static Problems, we found that, in the limit of mesh refinement, the solution to the finite element model would converge toward the true solution. We also saw that adaptive mesh refinement could be used to generate a mesh that would have smaller elements in regions where the error was higher, rather than simply using smaller elements everywhere in the model. In this post, we will examine a couple of common pitfalls […]
Modeling Electroosmotic Flow and the Electrical Double Layer
Microfluidic devices are so small that the micropumps and micromixers that control and mix the fluid inside the device cannot involve any moving components. Instead, they must take advantage of electroosmotic flow. Here, I will describe the concept of electroosmosis and the electrical double layer (EDL), and how to model these in COMSOL, walking you through two example models.
COMSOL Conference 2013 Bangalore Award Winners
After having excellent poster and oral presentation sessions at the COMSOL Conference 2013 Bangalore, winners for the top papers and posters were announced during the award ceremony. Selecting the best ones was indeed the toughest decision that the Program Committee had to make. It was observed that the presenters had conducted rigorous analyses using COMSOL Multiphysics, and many of them also had experimental validation for their work. Now I would like to congratulate the winners once more, and allow you […]
ABB Uses Electrostatic Simulation to Design Tap Changers
Households and industries alike depend on reliable electrical power. To serve the diverse power needs of end users and consumers, the electrical grid is undergoing a major overhaul to upgrade a technology that is over 100 years old. The new infrastructure — the smart grid — is being developed for reliable, economic, and environmentally friendly electrical systems. A great example of equipment for the smart grid comes from ABB. Along with many other products, ABB has introduced the world’s fastest […]
COMSOL Conference 2013 Bangalore Keynote Sessions
At the COMSOL Conference 2013 Bangalore we had three speakers who delivered each of their keynote talks to a full house. It was an interesting mix, with one speaker each from the government, academic, and corporate backgrounds. Here is a glimpse of what attendees got to listen to.
Meshing Considerations for Linear Static Problems
In this blog entry, we introduce meshing considerations for linear static finite element problems. This is the first in a series of postings on meshing techniques that is meant to provide guidance on how to approach the meshing of your finite element model with confidence.
Photos from the COMSOL Conference 2013 Boston
Thank you to everyone who came out to the COMSOL Conference 2013 Boston for making this year’s event superb as ever. Each year, it is great to see so many familiar faces and meet many new people. I would like to share some photos with you from the conference, here on the blog. Can you find yourself in any of the pictures?
