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.

The Institute of Electrical and Electronics Engineers (IEEE) is doing some really cool things for its members. Chances are that you have attended their top rated conferences, downloaded papers from IEEE Xplore, or participated in one of many local chapter events. For electrical engineers like me, IEEE certainly is a rock to lean on for continued education and to connect with colleagues from around the world. Even if you are not a member you can tap into IEEE resources such […]

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.

This week we have the honor of having Professor Wolfgang Joppich as a guest blogger. As you may know, COMSOL Multiphysics provides great default solvers for all applications. For the interested user, it is good to know that you can optionally tune or completely change the solver settings. We strongly recommend that you read this blog posting to get an experts’ perspective on the solver technologies offered by COMSOL. I am an avid reader of the COMSOL Blog and an […]

Optical fibers are used to transmit information in the form of light through an optical waveguide made of glass fibers. The light is sent in a series of pulses that can be translated as binary code, allowing the transfer of information through the fiber. Because such pulses can travel with less attenuation and are immune to electromagnetic disturbances, fibers are used instead of traditional metallic wires thus allowing data transmission over longer distances and at higher bandwidths.

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.

I will always remember a Geotechnical Engineering class I took during the pursuit of my Civil Engineering degree. It contained both the high and low points for that academic semester; the lab portion was a lot of fun, learning about (read: playing with) the different soils and clays existing in the state of Georgia. The final project, on the other hand, tasked us with designing a retaining wall to match certain specifications — a tough and lengthy assignment. A retaining […]

It’s always been hard to place the field of electrochemistry into a more traditional engineering field. Departments and institutions that focus on electrochemical applications can be found within the faculties of Chemical Engineering, Physics, Materials Science, Physical Chemistry, and even Civil Engineering and Electrical Engineering. I believe this is because electrochemistry is heavily involved in applications that are quite varied — and in some ways quite new. Electrochemical applications need to be studied before they can be understood and optimized, […]

If you’re the type of person who appreciates structure and ease-of-use, then as a COMSOL Conference 2013 registrant you will love the My Conference tool. This year we have revamped the system to let you quickly customize your conference program. Now you have the opportunity to add and edit your conference minicourse program whenever you prefer. We have also improved the functionality for presenters to edit and upload their abstracts and papers or posters, as well as get updates on […]
