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 […]

When you work with multiphysics all day you tend to notice physics phenomena everywhere you go. For me, one such moment was when I was walking on the beach this past summer. I noticed that the sand appears whiter around a person’s feet than elsewhere. You may have noticed this too, and like I, wondered “why?” This phenomenon can be explained by the theory of poroelasticity.

As you probably know by now, the European COMSOL Conference took place in Milan, Italy on October 10-12. As Phil has already mentioned in his blog posts, it was truly a remarkable event and I would like to share some of my impressions with you as well. This year’s program was packed with a wealth of very exciting presentations, training opportunities, and networking events.

As much as we would like to think that finite element analysis (FEA) is the be-all and end-all of simulations, it’s not true. There is also a camp of engineers out there that model integrated circuits and similar systems. These are based on different physics and equations than what FEA typically solves for. Yet, as is happening more and more in the world of virtual prototyping, the two types of simulations are converging. Now they need to integrate with each […]

About a month ago we had a webinar on CFD, and one of the demonstrated examples was the modeling of fluid flow from an inkjet. This technology has many applications and is a great example of how accurate CFD simulation is being used in the design process.

These days, RFID tags are used in many applications. Ranging from packing slips to ID badges, RFID tags are embedded into many different objects by businesses everywhere. Once tagged, these can be tracked to improve functions such as inventory management, security, manufacturing processes, and more. You can also implant an RFID tag into animals, such as cattle or pets, so that they can be found in case of theft or loss, for instance. Wild animals that are found far from […]

The “Gonzaga Room” at the COMSOL Conference in Milan was a pleasant setting for an interesting presentation. There, I saw Dejan Grabovickic present his paper titled: “Analysis of Super Imaging Properties of Spherical Geodesic Waveguide Using COMSOL Multiphysics”. His waveguide consisted of two copper spheres about the size of a soccer ball, one inside the other and separated by a very thin gap. I’m happy I attended this particular presentation, as it would later receive one of the Milan Conference […]
