Creating 2D Models from 3D Geometries in COMSOL Multiphysics

May 6, 2013

Our newest release, COMSOL Multiphysics version 4.3b, contains so many new modules and features, certain additions might get lost in the fray. One addition to the COMSOL Multiphysics base package we don’t want you to miss is the ability to create 2D models from cross sections of 3D geometries. This easy-to-use feature allows engineers to simplify the model, gain understanding of and fine-tune parameters, and dramatically reduce simulation time.

This Just In: COMSOL Multiphysics 4.3b

May 3, 2013

We’ve been dropping hints for the past few weeks here on the blog, and the time has finally come when we can officially unveil the release of COMSOL Multiphysics 4.3b. Five new products extend our product suite, and there are plenty of new features to enhance your simulation experience. The latest version of COMSOL Multiphysics is here, and you do not want to miss out on the news.

The Graphene Revolution: Part 4

May 2, 2013

Graphene can be created by way of thermal decomposition at high vacuum. In order to design and optimize these high-vacuum systems engineers might look to simulation, but there are currently not many modeling tools that are up to the task. Let’s have a look at how vacuum systems are relevant to graphene production, why you should simulate them, and how.

The Greenhouse Effect

May 1, 2013

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.

Wave Optics, to Approximate or Not?

April 30, 2013

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.

IEEE Spectrum Puts the Spotlight on Multiphysics

April 29, 2013

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 […]

On Solvers: Benefits and Limits of Solution Methods

April 24, 2013

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 […]

Step-Index Fiber Simulation

April 23, 2013

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.
