The Graphene Revolution: Part 2
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.
How to Model Multiphysics in Multimaterial?
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.
Introduction to COMSOL Multiphysics, a Book to Get you Started
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 […]
When Marshmallows Become Rock-hard
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.
Boosting COMSOL’s Cooperation with Siemens PLM Software
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 […]
What is Efficiency?
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 World: Human Space Flight and Autonomous Flying Robots
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 […]
Magnetic Shells Designed to Improve Energy Transfer
Engineers and scientists are known to step up to the challenges posed by nature. After developing an understanding of how the current object or process works, the next step often includes figuring out how to manipulate the situation to improve said object or process. One such example is cloaking; controlling light and sound waves to render something invisible. Phys.org recently ran a story on progressive research on controlling magnetic fields via cloaking to harvest and transfer energy using a magnetic […]
