Structural Mechanics Tutorials: Rigid Connector and Linear Buckling

Andrew Griesmer | June 6, 2013

Continuing our structural mechanics tutorial blog series, we have created two more videos of different functionality existing in COMSOL’s Structural Mechanics Module. The first post in the series introduced you to the Structural Mechanics Module via a linear elastic analysis of a bracket, and the following post included two supplemental videos for adding Initial Strain and Thermal Stress to the this model. Next up we have two more “mini-tutorials” — this time outlining the Rigid Connector feature and the Linear […]

Multiphysics Users Shine in COMSOL News 2013

Lauren Sansone | June 5, 2013

Multiphysics simulation is all around us, although everyone may not realize it. Simulation may be the last thing people consider when cooking breakfast on the stove, driving with their sun-roof open, or crossing a bridge, but behind these routine activities lies a team of engineers and researchers working to make it all possible — perhaps a team you’re part of. I hear bits and pieces of the cool things COMSOL users are doing with the software from my colleagues around […]

Meet the Program Committee for COMSOL Conference Rotterdam 2013

Tycho van Noorden | June 4, 2013

I have attended many conferences during my career, but until this year I have never been on the organizing side of the equation. Admittedly, I’m enjoying my new role as Program Chair immensely. With the help of my colleagues from all of the European COMSOL offices, I’ve put together the program committee for the COMSOL Conference Rotterdam 2013. Now it’s time for you to find out who they are.

Learn How to Model Electrochemistry with an Orange Battery Tutorial

Fanny Littmarck | June 3, 2013

Did your chemistry teacher use an orange or lemon to demonstrate the concept of a battery, back in the day? You might remember how she magically produced electricity by sticking a couple of metal nails into the citrus fruit, as the whole class watched in awe. What if we now used simulation tools to demonstrate how an orange battery works, and then use that as an intro to electrochemistry modeling?

3D Printed Cloaking Device in a Matter of Hours

Fanny Littmarck | May 31, 2013

It’s been almost a year since we declared 3D printing the hottest topic in manufacturing, and it hasn’t cooled off yet. If anything, 3D printing has seen a recent surge in popularity. By now you’ve heard a lot about the technology and what you can print with it, but did you know you could print invisibility cloaks this way, too?

In many applications, loads applied to structures are random in nature. The sampling results of the structural response will differ depending on the data collection time. Although the stress experienced is not always high, the repeated loading and unloading can lead to fatigue. The engineering challenges in these types of applications are defining the stress response to the random load history in the critical points, and predicting fatigue damage. This is simulated with the Cumulative Damage feature in the Fatigue […]

Meet the Program Committee for the COMSOL Conference Bangalore 2013

Prajakta Sabnis | May 29, 2013

The program committee for the COMSOL Conference Bangalore 2013 has now been established. Exciting times are ahead of us, and personally, I cannot wait to work closely with these experts from industry and academic fields, as part of the user’s conference in Bangalore.

Using Curvilinear Coordinates

Bjorn Sjodin | May 28, 2013

Curvilinear coordinates are a coordinate system where the coordinate lines may be curved. The new user interface for automatic computation of curvilinear coordinates is a very practical addition to version 4.3b for those working with anisotropic materials in free-form CAD designs. If you have a generic bent shape and try to apply the usual coordinate systems like Cartesian, cylindrical, or spherical, you are out of luck. Curvilinear coordinates are needed to smoothly follow the design, which typically has no mathematical […]

Modeling Electroanalysis: Cyclic Voltammetry

Edmund Dickinson | May 27, 2013

If you’re not an electrochemist, chances are you’ve never come across cyclic voltammetry. But look at any electrochemical journal, conference proceedings, or company website for manufacturers of electrochemical sensors. Somewhere near the front, you’ll see a distinctive “double-peaked” graph.

Mesh Refinement for Wave Problems

Kyle Koppenhoefer | May 24, 2013

This week we are happy to have Kyle Koppenhoefer of AltaSim Technologies as a guest blogger. As COMSOL Certified Consultants, AltaSim can share valuable insights into using the software — today on the topic of meshing wave problems. As part of our efforts to assist COMSOL users in performing high-quality analysis, we recently used our bi-monthly email to remind users to include twelve degrees of freedom per wavelength when meshing wave problems. This article builds on our previous advice. Wave-type […]
