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 […]

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 […]

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 […]

Ultra-precise optical components require blemish-free surfaces that often cannot be achieved by the machining processes that grind these components. Fluid jet polishing (FJP) is a new technology being developed by Zeeko Ltd to replace the hand polishing that was often required. With the help of COMSOL, Zeeko was able to create a product that polishes the optical components in only ten minutes instead of an entire day, and without waveforms.

The Structural Mechanics Module has numerous capabilities, enough for a video containing all of them to last days. This video demonstrates one of the many mechanical capabilities of COMSOL Multiphysics, by outlining a Static Linear Analysis. The chosen physics interface for this problem is Solid Mechanics, one of 13 physics interfaces in the Structural Mechanics Module. The video shows step-by-step how to set up the model of a bracket with a standard workflow (i.e. import the geometry, create global parameters […]

It’s that time of year again for all the foodies out there; on January 29th the 2013 Bocuse d’Or will be in full swing with 24 chefs each representing their country, vying for the Gold Medal in the Olympic Games of the culinary world. In this biennial event, the chefs will have to combine classical and innovative cooking techniques to come out on top. At the last Bocuse d’Or in 2011, Gunnar Hvarnes propelled past the competition with the aid […]

SOund NAvigation Ranging, or Sonar, has been an important part of naval warfare and since the 1950’s. Although it is a relatively simple way to locate objects, it’s the best for doing so in water, emitting sound waves and listening for echoes made by objects in the water. In today’s world of undersea warfare, the threats and the necessary responses to them are becoming more important and urgent. Sonar systems are required to detect these threats, making it necessary for […]

The latest version of COMSOL Multiphysics features a brand new way to use COMSOL. With LiveLink™ for Excel® you can modify and run COMSOL models in Microsoft Excel® 2007 or 2010. This combines the familiarity of Excel® with the physics simulation capabilities of COMSOL. Thus, making it easy for users of Excel to run multiphysics simulation without operating COMSOL themselves. A new LiveLink™ for Excel® video tutorial demonstrates the powerful combination. In the video, the main features to help you […]

Here’s a story we’ve all heard before: due to the inefficient nature and inevitable decline of fossil fuels, alternative energy resources are becoming increasingly popular. Wind energy is a popular source of alternative energy, with wind farms sprouting up all over the world. Here’s something you may not have thought about: lightning strikes are a major problem for these wind turbines. Intuitively, places with high wind speeds also have stormy weather, and a 150 meter tall metal pole makes an […]

Growing older is an inevitable part of life, and with it, our body slowly begins to show that. I recently started wearing eye glasses because my eyesight is weakening. It’s a little unnerving, but I am comforted by the ever-improving technology being produced. My hearing is still fully intact, but the same cannot be said for 17% (36 million) of American adults who report some degree of hearing loss. In most cases, regular hearing aids are sufficient in treating hearing […]
