You’ve seen glimpses of our new software release at the COMSOL Conference and perhaps engaged in commentary around it in social media. Today marks the official release of COMSOL Multiphysics version 4.4, and you can now learn about the software updates in detail and download it if you are on subscription.

I recently stumbled upon a neat tool from Autodesk┬« called “Autodesk┬« Homestyler”. It’s surprising to see they have rolled out a tool that is more entertaining than utilitarian, but if a CAD company were to develop something fun for the general population, I suppose an interior design app makes sense. We took it for a test-drive. Here’s how it went.

Joule heating is a fairly standard type of simulation for COMSOL users nowadays. It involves solving for electrical voltage and temperature fields simultaneously with highly temperature-dependent material properties. Controlling Joule heating is very important when designing and manufacturing electrical systems components. The electric protection group at manufacturing company Mersen France used to base their busbar and fuse designs on trial-and-error, but these days they turn to COMSOL Multiphysics.

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.

There were many interesting posters at this year’s COMSOL Conference in Boston. A couple that caught my eye involved microwave heating and chemical applications. One of them showcases the use of microwave irradiation to speed up chemical reactions. Another — one of the recipients of the Best Poster award — used simulations to optimize their microreactor design with respect to microwave propagation.

Over the past few years, Microsoft® has introduced updates to the user interface (UI) for its Office programs. Microsoft® Office 2013 is all about being touch-screen friendly, and Microsoft® Office 2007 brought the Ribbon interface. The Microsoft® Ribbon was designed to be easier to use than the nested drop-down menus of yore. These days, it’s what we’re used to seeing when working with their tools — and we’ve come to appreciate the ease-of-use, guidance, and clear workflow overview it provides. […]

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 COMSOL Conference 2013 Boston finished up on Friday last week. There were lots of excellent posters and user presentations, and some enriching conversations during the coffee breaks. On Thursday, our three keynote speakers took to the stage and treated us to each of their multiphysics simulation stories. Here’s a round-up of who presented and what they shared with the audience.

A Gaussian beam that is striking an array of nanorods is an example of optical scattering. Consider metallic nanorods that are very close together and have a diameter much smaller than the wavelength of a Gaussian beam that falls upon them. If the beam were to be polarized along the rods, they would act as though they were not actually individual rods, but a sheet of metal. The array is nearly transparent to the wave when it is polarized perpendicular […]

Wireless systems are growing increasingly thinner and more advanced. In order to keep this trend going, engineers must consider how to optimize the designs of the components that make up data transmission systems. One such component is the spiral resonator, which allows the system to communicate properly by filtering out unwanted frequencies and letting the appropriate ones through. Spiral resonator filter design can be analyzed and optimized using simulation software, as seen in a recent story from AltaSim Technologies.

Plate heat exchangers have a larger surface with respect to their volume as compared to a conventional shell and tube design, making for an efficient temperature regulation device. As the name infers, these types of heat exchangers consist of layers of corrugated metal forming channels in between. In order to optimize their performance, you need the flow through the channels to be well-distributed. As you can imagine, the flow is very detailed and modeling it can be computationally demanding, if […]
