Did your chemistry teacher use an orange or lemon to demonstrate the concept of a battery, back in the day? You might remember how she magically produced electricity by sticking a couple of metal nails into the citrus fruit, as the whole class watched in awe. What if we now used simulation tools to demonstrate how an orange battery works, and then use that as an intro to electrochemistry modeling?

It’s been almost a year since we declared 3D printing the hottest topic in manufacturing, and it hasn’t cooled off yet. If anything, 3D printing has seen a recent surge in popularity. By now you’ve heard a lot about the technology and what you can print with it, but did you know you could print invisibility cloaks this way, too?

Given the title of this blog post you might expect it to be about global warming, and I won’t blame you for it; greenhouse effect has become another popular term used when debating climate change. However, its original and literal meaning refers to a very different process, in particular when it comes to heat retention. Here we will describe the effect of heating up an actual greenhouse and suggest steps for optimizing its design.

Engineers working with lasers, optical fibers and waveguides, nonlinear optical processes, metamaterials, and other large photonic devices ultimately deal with wave optics. Photonic devices are considered “large” when they are larger than a wavelength of light. In that case, you deal with optics frequencies as opposed to radio frequencies, and the device is not complex enough to justify approximating with rays.

Each year in May we host a multiphysics simulation workshop specifically for U.S. government employees. This year’s agenda will provide attendees with an overview of COMSOL Multiphysics, tutorials, a user presentation, and more — all in a setting that allows classified work to be shared among federal employees and contractors only.

Chemical reaction fluids can be cooled using glass flanges. The reaction fluid is passed through the flange and the air surrounding the flange then serves as the coolant. Engineers looking to optimize the cooling performance of such flanges can look to simulation for help.

Everyone’s talking about graphene right now. When was the last time a material received this much attention? Sure, other materials have peaked our interest before, but when something breaks into more mainstream news you know it’s going to be a very big deal.

We’ve all encountered hinges before; they are frequently used to connect different parts of mechanical assemblies in a way that allows them to move freely relative to one another, in a single degree of freedom. There are several different types of hinges, including everything from barrel hinges to friction hinges, with lots in between. Before incorporating a hinge into a mechanical assembly, you might want to get a sense of how it will hold up by performing a hinge analysis.

In the world of bearings, there are many different types to choose from. For certain applications, magnetic bearings trump their mechanical counterparts in several regards. In order to understand how the bearing will perform, using a simulation tool to calculate design parameters is a good idea.
