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?

Who loves coffee? That’s what I thought; most of you. I for one cannot go a day without fueling up on coffee. Now that fall is on its way, the cooler weather will require better insulation of my coffee when I take it to-go, in the name of a travel mug (i.e., a thermos). This leads me to wonder: how long will coffee stay warm inside a thermos if I bring it outside?

There’s a lot to be excited about for this year’s COMSOL Conference — and it’s just around the corner. We thought, what better way to give you a clearer idea of what to expect from the COMSOL Conference 2012, than with a video?

In these days of globalization, keeping the world connected is imperative. Information needs to pass as freely and quickly as possible in order to keep markets up-to-date with the latest news and to ensure that commerce can be conducted without hindrance (at least of the technical kind). So what do you do – look to the sky? The answer is no; in fact, 99% of this information is carried by undersea cables. These unsung heroes sit at the bottom of […]

If you’re a cynic (like I am sometimes), the term “multiphysics” might irk you. There’s only one set of physical laws, after all. There’s nothing “multi” about it. So what is multiphysics?
