Metamaterials are a new and emerging technology with vast potential to reshape our views on what is and isn’t possible in this physical world of ours. Unlocking the mysteries and overcoming the obstacles associated with metamaterials would lead to a host of technological advances once thought impossible by even the most imaginative of individuals. From making computer chips smaller and faster than the most advanced current ones, to protecting structures from earthquakes, to developing imaging technology that doesn’t harm tissue […]

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.

“The Bumblebee Flies Anyway” was a book by Robert Cormier that I read as a young teenager. In it, Cormier describes how bumblebees are natural anomalies as they seemingly do not have the aerodynamic capability to actually fly. Their wing span and flapping speed should not provide enough lift to allow flying, and this is a fact that I have always associated with bumblebees since. Yet, this has been proven not to be true, as a closer investigation of the […]

Having used COMSOL Multiphysics for over six years now, we are pleased to have Dr. Jon Ebert, Director at SC Solutions, join us in the next Mechanical Engineering Magazine Webinar Series titled “Heat Transfer in Solid and Fluids”. On March 7th, he will co-host an instructional webinar together with COMSOL’s John Dunec. Dr. Ebert will discuss SC Solution’s simulation activities within a wide span of heat transfer-related applications, particularly with respect to semiconductor manufacturing. As a long-time user of COMSOL […]

The electrical grid describes the network created for producing electricity, transmitting it and delivering it to the consumers. A “smart grid” is an electrical grid that gathers information on the suppliers and consumers automatically to improve efficiency and sustainability in the system. As the automated technology improves, the hardware that physically connects the electrical grid together must improve as well. This hardware, the “nuts and bolts” of the grid, is comprised of transformers, cable joints, terminations, bushings, and fault current […]

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 […]

Induction occurs when a metal object moves in the presence of a magnetic field inducing a current in that object. The induced current causes it to heat up (called inductive heating), as all current does. Yet, simulating these two coupled physics together can be difficult to do as they are intrinsically based on different time scales. COMSOL Multiphysics is able to cleverly simulate them through combining the frequency domain modeling of the magnetic field with a stationary simulation of the […]

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.

In a popular post from last year, I discussed accessing and manipulating the underlying equations in COMSOL. This blog post instigated reader comments, and most of the respondents appreciated, or even required, the ability to look at the mathematical model (i.e., equations) behind the physics. While considering this, I realized that there is more to the story, and with a little perspective, the community could benefit from further discussion.

As discussed in On Solvers: Multigrid Methods (referred to as “Part 1″), iterative methods eliminate oscillatory error components efficiently while leaving the smooth ones almost untouched (smoothing property). The main idea behind multigrid methods is to use the smoothing property, spatial aliasing, and the residual correction to the advantage of convergence. Before putting all the pieces of this proverbial puzzle together, we need to introduce residual correction and, even though we talked about it in the previous blog post, dig […]

Decisions have been made, locations have been selected, and the dates have been confirmed. The COMSOL Conference 2013 has been finalized and you are all invited! While October may seem a ways off for many of you, I know there must be some “planners” out there, like me. If you too like marking your calendar, here are this year’s conference dates: Boston, MA: October 9-11 Bangalore, India: October 17-18 Rotterdam, Netherlands: October 23-25 Singapore, Singapore: October 24-25 Taipei, Taiwan: October […]
