In a previous blog entry I discussed some of the exotic properties of graphene. The fact that graphene consists of a single layer of atoms means the aspect ratio of any graphene-based structure may be very high. High aspect geometries present their own array of modeling challenges.

Dr. Raj Thiagarajan is a prolific producer of interesting research articles ranging from waste-water treatment to acoustics metamaterials, and lots in between. As the Managing Director at ATOA (“Atom TO Application”) Scientific Technologies, a COMSOL Certified Consultant, Raj has had to simulate all types of applications. Now he will show you how to use multiphysics simulations in multimaterial and composite product design.

About 13% of the world’s power is nuclear. During the 1990′s, this figure was almost 18%. This trend may continue to decline or undergo a renaissance, but in the meantime nuclear waste disposal remains a hot topic among engineers and governmental agencies. Safe procedures for the disposal of nuclear waste have been in place for decades, and continued improvement of these techniques remain in discussion today.

What does it take to get started using COMSOL Multiphysics? Of course, it depends on where you set the bar. However, grasping the workflow and handling the basic tools can be relatively easy to pick up. To make this process even smoother, first-time users will benefit from the recent major update of the COMSOL Multiphysics instruction manual. The book, Introduction to COMSOL Multiphysics, is a valuable tool for learning COMSOL simulation software and the new version is now available for […]

A while back, I bought a bag of marshmallows, indulged a bit, and then forgot about the opened bag for a few weeks. To my surprise, and disappointment, when my marshmallows cravings returned the top ones were rock-hard while the bottom ones were almost as soft as when I bought them. Why was this the case? By leaving the bag open, water had migrated from the marshmallows into the air.

In April last year, we entered into a partnership with Siemens PLM Software and started developing the functionality that would connect COMSOL Multiphysics® simulations to Solid Edge® CAD modeling. Siemens gave us access to their tool, and we were quick in developing LiveLink™ for Solid Edge® as part of the version 4.3a release. This project led to boosting our cooperation with Simens PLM Software, as we had already implemented Parasolid® to be an integral part of the CAD Import Module […]

If you’re in the business of designing transducers, resonators, actuators, or sensors, odds are you deal with piezoelectric materials — a key component in these devices. As we’ve said before, multiphysics simulation should play a central role in the product design-stages to ensure top quality without wasting time or money. For those of you who design piezoelectric devices, we have an upcoming piezoelectric simulations webinar on February 28th.

Transformers are used to increase the voltage of an alternating current (AC) before moving it along the power grid via power lines. Since power lines lose energy through heating cased by electric currents, you can achieve more economical power transmission by transforming to a high voltage and low current. As a matter of fact, high voltage (HV) power transmission lines transmit portions of its power in the air surrounding it. Furthermore, as the current travels long distances through many transformer […]

Students at Ohio State University can take a course on numerical simulations in biomedical engineering with Richard T. Hart. In the course, they will learn how to use computer modeling to solve biomedical engineering problems. Hart is now providing anyone who is interested in this application area with three video tutorials from the course via the Ohio State University iTunes U page.

When I first heard about Carnot’s theorem, I was impressed with its simplicity. Yet, no matter the amount of hard thinking we put into the design of everyday heat engines, we will never reach the efficiency of a Carnot engine. Still, modern-day heat engines are still effective as they get us from point A to point B by car or truck.

SolidWorks always puts on a great show. I just got back from SolidWorks World where I was able to go to a number of technical sessions, and understand how CAD design can better complement finite-element analysis. We had a booth there, and it was great to meet a few COMSOL users, who like to use SolidWorks® and COMSOL Multiphysics together via LiveLink™ for SolidWorks®. I also got to meet potential customers-to-be. In typical SolidWorks World fashion, I and the other […]
