During my time as a PhD student, a blue “Chemical Landmark” plaque was fitted to the building a couple of hundred yards down the road from my lab. The plaque commemorates the achievements of the researchers who made the lithium-ion (Li-ion) battery viable. Whether or not you know about the electrochemistry of rechargeable lithium-ion batteries, you probably rely on one. We carry them around in our phones and laptops, and ride in cars and planes that use them for power. […]

It’s not always obvious what a major role temperature control plays in modern technology, as the interchange happens in the background. Plate heat exchangers, made up of successions of metal plates and various coiled pipes, regulate and manipulate temperature, and they get the job done quickly — thanks to an active surface that is large with respect to their volume.

Quite often we get asked the question “can I 3D print my COMSOL model?” Well, as of version 4.3b, the answer is “yes!” This is because it is now possible to export geometries and meshes as STL files, which is one of the standard file formats for 3D printing. This allows for rapid prototyping of designs; there is no need to outsource parts to machine shops. It is quite remarkable that you could conceive, simulate, optimize, and prototype a design […]

Sharp is a powerhouse in the electronics industry, involved in televisions, liquid crystal displays, LED lighting systems, solar cells, multi-function business machines, and many other electronics-based products. One of a global network of Sharp R&D laboratories, Sharp Laboratories of Europe (located in Oxford, England), has been busy researching and developing LED lighting, display technology, microfluidic lab-on-a-chip, and energy systems for incorporation into Sharp’s products.

I’ve written several blog entries involving permanent magnets, in one way or another. Reading those may have raised the question “what about a more simple introduction to permanent magnet simulations?” Fair enough, here’s how to model a permanent magnet and its surrounding magnetic field.

The Coplanar Waveguide (CPW) is commonly used in microwave circuits. COMSOL Multiphysics, with the RF Module, makes it easy to compute the impedance, fields, losses, and other operating parameters needed when designing a CPW.

Deadlines always approach faster than expected, and the early bird abstract submission for the COMSOL Conference 2013 is no exception. This is why I have put together a simple abstract submission guide to help you through the submission process. Submitting your abstract by the early bird deadline not only means saving on your registration fee (something your boss and budget are sure to appreciate), but it also gives you the possibility to interact with your Program Chair and the Program […]

If you roast a turkey for dinner and you need to check the temperature, the technology exists to find it. But what happens if the temperature is so hot that a consumer-grade thermometer, or any man-made device, really, would instantly melt and be destroyed? This might not be a common occurrence in your kitchen, but it is a real concern in blast furnaces, where temperatures can reach close to 1,500°C. Simply guessing is far from safe. Luckily, by simulating with […]

The fact that oil and water don’t mix is something that you are probably all familiar with. At one point or another, you’ve most likely noticed what happens when you shake a bottle of say, Italian salad dressing, and the liquids mix momentarily, only to become separated again within seconds as oil bubbles rise to the surface. Creating a simulation describing how these two immiscible fluids interact is a great way to introduce computational fluid dynamics (CFD) applied to two-phase […]

A swashplate mechanism, used in a helicopter to control the pitch of the rotor blades, can be easily simulated using the Multibody Dynamics Module available in COMSOL Multiphysics. This module enables simulation of an assembly of flexible and rigid bodies, together with physical phenomena from fluid, heat, and electrical applications, among others. Here, we will show you a model to convey how a swashplate mechanism works and at the same time analyze the stresses and deformation in the flexible rotor […]

Did you know that you can combine the strengths of COMSOL Multiphysics® and MATLAB® in real time to solve engineering simulations? To me, that sounds like getting the best of both worlds. Let me explain.
