The first computer I used was a real performance beast. Equipped with Intel’s 486 clocking in at 66 MHz, this machine was ready to take on whatever challenges the future would bring us. Or so I thought. The CPU clock speeds increased and soon passed 500 MHz, 1 GHz, and continued upwards. Around 2005, the top speed of the high-end processors settled around 4 GHz and hasn’t increased much since then. Why is that? I’ll explain.

How the sun, solar system, and planet Earth formed and how life began are fundamental science questions that still remain unanswered. Today, we may be one step closer to answering these questions, because the spacecraft Philae, which is aboard the Rosetta, is in the process of landing on a comet for the first time ever. I was able to interview two of the scientists involved in this project to gain insight into how Rosetta’s mission may answer these very questions.

With its growing use in numerous applications, the demand for graphene has steadily increased over the years. This heightened interest has prompted new research behind the methods for synthesizing graphene — one of which is chemical vapor deposition. See how one research team used modeling to analyze and enhance the CVD graphene growth mechanism.

Around this time last year, we introduced a new ribbon user interface to COMSOL Multiphysics. Now, with version 5.0, we are introducing many improvements that make COMSOL Multiphysics more intuitive to use. Updates include a change in color scheme, additional multiphysics interfaces, a materials tab, global materials, and Material Sweeps and Function Sweeps.

In addition to the general Solid Mechanics interface, the Structural Mechanics Module consists of specialized interfaces: Shell, Plate, and Membrane for the modeling of thin structures; and Beam and Truss for modeling slender structures. An engineering structure that has a mix of solid, thin, and slender components can be modeled by combining these physics interfaces with each other. Here, we will explore the options for coupling the structural mechanics interfaces by using examples from the Model Library.

Probably the most common reactor in the chemical industry is the packed bed reactor. This reactor is used in chemical synthesis and for effluent treatment and catalytic combustion. Oftentimes, heterogeneous catalysis requires packed beds. A common design is a cylindrical column filled with catalyst pellets. The pellets can be contained within supporting structures, like tubes or channels, or packed in a single compartment in the column. The latter is called dumped packing.

Figure skating is a beautiful but dangerous sport; repetitive jumping and landing on ice can cause a lot of joint stress. Researchers are working on “smart” blades to measure the force that is exerted on the ice. The data could then be used to prevent injuries.
