Why Should You Simulate Fatigue?

October 8, 2012

The Fatigue Module, an add-on to the Structural Mechanics Module and the COMSOL Multiphysics® software, can be used to perform structural fatigue life computations for both strain-based and stressed-based fatigue. In this blog post, we discuss some of the potential application areas and benefits of fatigue testing.

Extend Your Modeling Capacity with LiveLink™ for Excel®

October 3, 2012

Recently, Fanny blogged about spreadsheets and how they are used in engineering. She mentioned that they are great for collating material properties and other experimental results, and for then using these in COMSOL models. The simulation results from these models can in turn be compared to the original data, and help calibrate material properties and optimize the design. With the release of COMSOL Multiphysics 4.3a, COMSOL has now made it much easier to perform these tasks and extend your modeling […]

COMSOL 4.3a Highlights Video — New Products and Features

October 2, 2012

Yesterday we announced the release of COMSOL Multiphysics Version 4.3a. The excitement around this release is already rising, and with good reason. Now we’d like to introduce you to the four new products and some of the major new features that are made available, via this COMSOL 4.3a Highlights video duo:

Equations: Who Needs Them?

September 28, 2012

Most of us take mathematical modeling for granted. After all, we’re taught physics and calculus almost hand-in-hand. But we owe a lot to the early pioneers like Isaac Newton, who demonstrated and strongly promoted interpreting natural phenomena through equations. Differential equations are especially useful since most things change as time marches on. Since we live in 3D space, partial differential equations (i.e., equations that express change in more than one “direction”) arise as the prominent tool to express continuum level […]

Preview: Virtual Conference Guide for Smartphones and other Web-enabled Devices

September 27, 2012

The COMSOL Conference is about to get kick-started with its first stop in Boston next week, and Milan to follow soon thereafter. Now we’re excited to announce a new feature for this year’s conference attendees: a virtual conference guide for smartphones and other web-enabled devices. The full version is yet to be released, but I was able to test-drive the app and will share it with you here on the blog.

Fatigue — When Cyclic Stress Produces Fractures

September 26, 2012

Many of the products that engineers design experience cyclic stresses during use that are below the material’s yield stress; unfortunately, these stresses can still be the primary reason for failure. Thus, engineers and designers must find ways of including the effects of cyclic stresses when designing products for long-term use.

User Tip: All About Icons

September 25, 2012

I give a lot of COMSOL workshops — about 20 so far this year. These are great events and they include hands-on minicourses, which allow me to connect with the audience. One topic that I often spend a few minutes on might surprise you: icons. The icons, especially those found at the nodes in the Model Builder, are packed with useful information. They’re easy to miss because they’re small, but knowing what they mean can be a big help.

Why Adopting COMSOL Multiphysics Is a Good Career Move

September 21, 2012

Are you a student thinking about where you want to end up after graduation, or a young professional considering how to make yourself more valuable in today’s job market? There are many things you might do to sharpen your skills and bolster your résumé, but here’s a piece of advice you’ll get from us: adopting COMSOL Multiphysics is a good career move. Before you say “of course you’d say that, it’s in your best interest if I use your software,” […]
