The ability to adapt to unpredictable or dangerous environments is an important advantage for any vehicle or device. Developing materials with the ability to shift in shape can offer potential for new technologies to handle such situations. With the design of a new hybrid material, engineers at Cornell University are bringing new developments of this nature to the fields of soft robotics and aeronautics.

You can use the residual operator, new with COMSOL Multiphysics version 5.2, to evaluate and plot your model’s algebraic residual in order to troubleshoot convergence issues. This blog post demonstrates the use of the residual operator for visualizing and understanding the convergence properties of a turbulent flow simulation.

Behind every glass of beer is a series of steps that deliver its unique taste. Fermentation, the process during which sugars are converted into alcohol, is one of these important steps. With the help of COMSOL Multiphysics, we can study the fermentation process, identifying ways to optimize its efficiency and serve up a better-tasting beer.

We’ve talked a lot on the blog about the different types of simulation apps that you can build. But did you know that you can create an app that plays sounds? The Organ Pipe Designer allows users to investigate the parameters behind an organ pipe configuration and then play the resulting sounds to really see — and hear — a design in action. Let’s learn more about the physics behind our underlying model and its transformation into an easy-to-use app.

Removing bacteria and contaminants from water is an important point of concern for safety reasons. One method of purification involves the use of water treatment basins. CFD modeling provides an efficient route for optimizing the design of these basins to ensure their overall effectiveness. Simulation apps, as we’ll highlight here, are taking things one step further by extending the scope of such modeling capabilities to a much wider audience.

The Newman model and its variants form the standard theory used to successfully predict the behavior of lithium-ion battery design under a range of operating conditions. In the Newman model, the geometry of the porous structure of the battery electrodes is not described in detail; instead, typical averaged dimensions are used as input to describe the electrodes as homogeneous and isotropic materials. But how accurate is this approach compared to a detailed, heterogeneous geometric model? Let’s find out.

Magnetic gears are the contactless mechanisms for torque-speed conversion using permanent magnets or electromagnets. They are utilized in several renewable energy applications, increasing the speed of wind energy, ocean energy, and flywheel energy storage in order to match the specification of the electromagnetic generator. Unlike their mechanical counterparts, magnetic gears offer inherent overload protection, have high reliability due to frictionless operation, and require no lubrication. Today, we’ll discuss how to simulate magnetic gears in 2D and 3D with COMSOL Multiphysics.

We previously wrote about how engineers at IAV, a leading automotive engineering company, used simulation to reduce sloshing in vehicles. Today, we’ll demonstrate how to set up your own sloshing tank model in COMSOL Multiphysics using a separated two-phase flow model with two fluids that have a large difference in density.

Inductive devices exhibit a range of electromagnetic effects that have to be taken into account when they are utilized as part of any application. With the tools provided by the AC/DC Module in COMSOL Multiphysics, you can model and design an inductor in a straightforward yet accurate way, as well as calculate the device characteristics your application demands.

We’ve learned how to simulate a simple bit-by-bit holographic data storage model in COMSOL Multiphysics by choosing an appropriate beam size and implementing the recording and retrieval process. Today, we step forward and demonstrate how to simulate a more difficult and complex, yet more realistic and interesting model of a holographic page data storage system.

We can solve many of the world’s energy sustainability problems by harnessing the power of the sun through fusion energy. Tokamaks are devices that test the practicality of employing fusion energy on Earth. ITER, which will be the largest tokamak on Earth when complete, has required years of research and a magnitude of resources. Using COMSOL Multiphysics, a group of researchers investigated whether the tritium breeding modules (TBMs) in ITER produce magnetic perturbation that could generate unacceptable plasma losses.
