Multiphysics Simulation for Better and Faster Sonar Development

December 18, 2012

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 […]

Lightning-Proof Wind Turbines

December 4, 2012

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 […]

Simulation-Based Design of New Implantable Hearing Aids

November 29, 2012

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 […]

New Product Video Tutorial: LiveLink™ for Solid Edge®

November 22, 2012

With the latest COMSOL release, Version 4.3a, comes new CAD interoperability. We are delighted to introduce LiveLink™ for Solid Edge® seamless associativity between Siemens’ CAD experience and COMSOL’s multiphysics simulation software. A LiveLink™ for Solid Edge® video tutorial demonstrates this integration, and gives you a leg up in your design modeling. In this video, the three main features to help you design, optimize, and troubleshoot your geometries are demonstrated.

Modeling Scar Effects on Electrical Spinal Cord Stimulation

November 21, 2012

Spinal cord stimulation (SCS) is a treatment for chronic back pain that has been around for over 40 years. It involves implanting electrodes that apply electric potentials directly to the spine, interfering with the human pain signaling circuitry. The body attempts to send pain signals to the brain, but the electrodes act as a barrier preventing the signals from reaching the brain. Although an overall successful method for treating back pain, researchers have been improving on the design since the […]
