December of 1903 marked the commencement of the Age of Powered Flight, and the Wright brothers went down in history. This was a time before personal computers and simulation software existed. Determining the optimal design of their airplane had to be done using physical prototypes and real-life experiments. What had the design looked like if the Wright brothers had been able to use computers and modeling software? Three researchers from Pennsylvania State University sought to find out how the design […]

A mixer that doesn’t move may sound like an oxymoron, but it’s not. Used in various chemical species transport applications, static mixers are inexpensive, accurate, and versatile. Still, there is always room for improvement. Optimizing the design of static mixers calls for computer modeling, but traditional CFD methods may not be the best way to model these mixers. How do these motionless mixers work and how can their performance be simulated?

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.

They say that an image is worth more than a thousand words, and I couldn’t agree more. In that vein, we’d like to show you our enthusiasm over the European COMSOL Conference held in Milan, Italy earlier in October, through a slideshow of pictures from the event. We already thanked you in advance for making this our most-registered for event of the year. Now we want to thank you again with this slideshow.

I’m back on the blog with the latest installment in the Postprocessing and Visualization Videos series. The two-part video shown here covers “Basic Visualization”. Chapter 1 and 2 will give you an overview of COMSOL’s visualization tools so that you can optimize how you view your model, both while setting up your physics and while postprocessing. I explain two tricks in the video that I’d like to draw your attention to in particular.

Since I joined COMSOL in 2010 I’ve presented about half a dozen webinars. Last week we held a webinar on Vacuum System Simulations and it was definitely the most fun webinar to-date. Historically, simulation has not been used extensively in the vacuum industry, so I was nervous that there wouldn’t be much interest in such a specialized topic.

When you need to mix something at a very small scale you don’t reach for a teeny-tiny whisk. If you’re working with microscale biochemical applications you’d be more likely to rely on diffusion to mix fluids. With highly ordered laminar flow there is no turbulence involved, thus making diffusion a prime candidate for “getting the job done”. But what if you need to mix larger molecules? Larger molecules mean higher molecular weight, which in turn leads to very long equilibration […]

What if this Halloween you could take your costume to the next level and turn yourself invisible? There are bounds of references to invisibility throughout fairy tales, folk lore, and pop culture. From capes and hats to cloaking devices, many fictional characters have been provided with a means for rendering themselves invisible. In the spirit of Halloween, let’s have a closer look at cloaking from a fictional and scientific stand-point.

Out of all metals, the most frequently extruded is aluminum. Aluminum extrusion entails using a hydraulic ram to squeeze an aluminum bar through a die. This process will form the metal into a particular shape. Extruded aluminum is used in many manufacturing applications, such as building components for example. The process of shaping metal alloys, like aluminum, can be modeled using COMSOL Multiphysics.

AMD has a new architecture for their graphics cards called Graphics Core Next (GCN). Perfect for compute-intensive applications, the new W-series are optimized and guarantee ultimate performance for visualizing and working with geometries and complex models. COMSOL is proud to announce that we now support the new W5000 and W7000 AMD FirePro™ Graphics Cards. This continues the partnership we have with AMD that I highlighted in a previous blog post about AMD FirePro graphics cards.

It’s no secret that there’s a lot of guesswork involved in oil production. Oil companies make “Big Money” decisions based on estimates – estimates with huge margins of error. What’s more, there is an incredible amount of risk involved, but with the potential for a large pay-off if all goes according to plan. The plan is based on “best guesses” and less than perfect data. Still, there are many big players in the oil industry that are doing very well […]
