A broken street sign turned into an online contest at the Dutch university TU Delft earlier this month. The TU Delft Webcare Team challenged their social media fans to determine what wind speed led the sign to buckle over — and the winner happens to be a COMSOL user. Here’s how Rob Eling solved the street sign challenge using COMSOL Multiphysics.

A little while ago we wrote about being Intel® Cluster Ready (ICR) certified and the advantages for companies in need of high performance computing (HPC). The conclusion of that blog post was that you can install and run COMSOL Multiphysics on any ICR cluster without additional preliminary work. There is a solution even simpler than that, thanks to a joint project between COMSOL Multiphysics GmbH and Fujitsu in Germany, called Ready-To-Go+ (RTG+). RTG+ is a complete solution, bringing you an […]

Microelectromechanical systems, also referred to as MEMS, involve very small devices, such as actuators, sensors, and resonators for instance. Inherent to the design of these devices is the coupling of many physics. Therefore, if you are an engineer who designs MEMS devices, you are likely familiar with multiphysics simulation software. If not, you can learn how to model these devices in our upcoming free webinar.

The future of high performance computing (HPC) is in clusters and parallel computing. The last single processor computers on the TOP500 list disappeared in 1997 — more than 15 years ago. Clusters allow us to compute larger and more detailed models faster than ever before, but taking the step into the world of HPC can be a challenge. A lot of time, money, and research must be invested when building a cluster from scratch. What kind of hardware should the […]

In June it was time for the International Supercomputing Conference (ISC) in Leipzig, Germany. Many of the largest hardware and software vendors for High Performance Computing (HPC) were there to present new equipment, and the latest TOP500 list, a list of the fastest supercomputers, was presented as well. In a world where we continuously demand faster computations and higher resolution in our models, it’s not only necessary to have better hardware; we also need software that can handle the ever-growing […]

Recently, I was given a copy of the book Finite Element Modeling Methods for Photonics, by B.M. Azizur Rahman and Arti Agrawal. This book proved to be a good companion to the RF Module and Wave Optics Module for graduate students starting in photonics and new users of COMSOL who would like a very targeted introduction to the field. The website accompanying the book comes with some sample computer codes used by the authors in simulation that readers can use […]

You may be familiar with the humming start of the mechanical fan that turns on when booting up your laptop computer. Such a fan is necessary to prevent electronic devices from overheating, and the accompanying whirring sound of the cooling system is an unavoidable side effect. As electronic devices become smaller, this mechanical fan must decrease in size as well, and therefore spin faster and faster in order to deliver the same amount of heat dissipation as a larger fan. […]

There are many necessary steps required in order to create a superior product. Based on some initial (or existing) design, you first need to evaluate the physical characteristics of the system. Once some level of understanding of the system has been obtained, it should then be possible to refine and optimize the design based on some reasonable choice of a figure of merit for a good design. The final stage is to prototype the design, which is where 3D printing […]

Last month, the Acoustical Society of America (ASA) and the Canadian Acoustical Association (CAA) held the 21st joint meeting of the International Congress on Acoustics (ICA) in Montreal, Canada. This joint congress is one of the major acoustics conferences of 2013, featuring a range of parallel sessions that covered most topics in acoustics. These included, among other things, psycho acoustics, underwater acoustics, transducer modeling, acoustics of musical instruments, nonlinear acoustics, and many more. This year’s acoustics conference also featured a […]

It’s been a busy and exciting past few weeks here at COMSOL, with the recent release of COMSOL Multiphysics 4.3b and all the updates it entails. We have been working on quite a bit of release-related content, including creating videos about the capabilities added to the COMSOL family, making updates to the Introduction to COMSOL Multiphysics tutorial, and generating many new simulations using the new features and modules. In the same vein, we’ve also been working to put together the […]

As computer hardware becomes more powerful and affordable, simulations are becoming commonplace in new disciplines of science and engineering. Food science engineering is one such area, and there is no shortfall of publications using COMSOL Multiphysics for food-related simulations. Such kinds of analyses pretty much always require several types of physics to be practically relevant.
