When Marshmallows Become Rock-hard

Valerio Marra February 25, 2013

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 […]

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 […]

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 […]

I noticed a lot of activity when I posted the question concerning “FEM vs FVM” in a previous blog post, so I started looking into it a bit. A lot of people went to the COMSOL Discussion Forum thread on the matter, from the blog, which got me thinking that this must be a hot topic out there. Not Much Debate How disappointed I was when I typed ‘FEM vs FVM’ into Google and saw that there wasn’t much to […]

An interesting discussion has been going on in the COMSOL Discussion Forum. What is the difference between the Finite Element Method (FEM) and the Finite Volume Method (FVM)?
