Simulation-Based Design of New Implantable Hearing Aids
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 […]
Coal: The Energy of Right Now
While alternative energy is the energy of the future, fossil fuels are the energy of right now. Coal, especially, is still heavily relied on for energy production and is a primary source of electricity generation in many countries including the US and China. In fact, world coal consumption is actually increasing year-to-year. Scientists need to be concentrating on how to make alternative energies more widespread, but they also need to make coal a better, more efficient fuel source. Designing systems […]
Simulating Permanent Magnet Generators
Permanent magnet generators, or PM generators as they are also called, generate power without batteries. PM generators consist of a magnetic stator coiled with wire and a wheel with permanent magnets rotating inside the stator. From motorcycles to wind farms, PM generators can be used in many electrical machinery applications. Let’s take a look at how these types of generators work and how they can be simulated.
Impedance Boundary Conditions Help in Modeling Non-Destructive Testing (NDT)
How do you simplify a 3D geometry to reduce the computational resources required to model it? Do it in 2D. What if the phenomenon can only be properly simulated in 3D? Find the planes of symmetry and reduce the size, most engineering objects are symmetric in some way. What if there is no symmetry, such as the propagation of random cracks through a steel pipe? Well, as this story from COMSOL News shows, there are other methods, such as using […]
Investigating the Fundamentals of an “Old” Technology
Transformers were first commercially used in the late 1800’s, but they are still being investigated at their fundamental levels. One of the stories from our latest COMSOL News concerns ABB (who themselves have been around since the late 1800’s) and their research into these apparatuses.
Now There’s Thermal Cloaking
As an avid reader of the physorg.com blog, I was pleasantly surprised to see a figure show up that could only have been made with COMSOL Multiphysics. Reading the article on thermal cloaking, I understood why.
What Is the Nature of Pain?
A second user story for the next COMSOL News is also reaching completion with exciting results (read about the first one here). This is an interesting case as it wasn’t really a group of people traditionally associated with finite element that managed to perform some pretty sophisticated modeling. In fact two of them are medical doctors while the final one has his background in physics.
