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.

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.

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.

We are very excited for our upcoming multiphysics conference in Milan this October. We have received many high-quality abstracts for this year’s event and we are happy to see that so many of you have registered to attend. The COMSOL Conference Milan 2012 will be our biggest event so far — and we have you to thank for that.

We’ve noticed that a lot of our customers use spreadsheets, such as Excel®, as part of the modeling process. They use them for storing material property and other data, such as from experiments or other information about workflow associated with their engineering project, and then import this data into COMSOL Multiphysics®. Spreadsheets are also the forum for taking in results from COMSOL software and using this to compare, optimize and verify these material properties. Let’s delve deeper into how spreadsheets […]

In short, electronic computer-aided design (ECAD) is typically used to design and develop electronic systems. Although it’s a mere letter away from spelling out “CAD”, there’s actually more to the story than appending the word “electronic” to “CAD”. So what is ECAD and why is it used in Finite Element Analysis (FEA)?

Located not far away from our Burlington, MA office is the ZINK Imaging Image Science Laboratory. The manager of that lab is a brilliant COMSOL Multiphysics user, Dr. William Vetterling. With over 60 published scientific articles and books, and 30 U.S. patents, Dr. Vetterling truly understands numerical modeling. At the COMSOL Conference in Boston he is going to speak about “The Library of Babel” — and you are not going to want to miss his presentation.

At the heart of any simulation software are the solvers. Those are things that take geometry/mesh/physics to the computational results. While it’s convenient to think about solvers in terms of the type of study (think time-dependent, parametric, or eigenvalue), there is a hierarchy of solvers that are usually employed. And at the foundational level of any simulation — and for every iteration — there is a linear solver.

Coupled physics phenomena (like electrical heating, fluid structure interaction, and conjugate heat transfer) demand multiphysics, which I’ve written about previously in “What is Multiphysics?”. But what if you just have a simple analysis to do — one that has been simplified to the point where only a “single physics” (to coin a term) is considered? What benefits does multiphysics have for this?
