Use Editor Tools to Simplify Your App-Building Process

Bjorn Sjodin | December 8, 2015

In the Application Builder, included with COMSOL Multiphysics version 5.2, the new Editor Tools window makes it possible to create simulation apps with a lot fewer clicks of the mouse. In this blog post, we will demonstrate how to create an app with Editor Tools using a simple simulation example, as well as show how to perform common user interface creation tasks more easily.

Microchannels are versatile structures that can be used for thermal management. One way to optimize heat transfer within such systems is by adding a pin fin heat sink to the microchannel configuration. Applying this approach, a team of researchers created a novel pin fin design, analyzing its heat transfer efficiency with COMSOL Multiphysics. They presented their innovative work at the COMSOL Conference 2015 Boston.

Healthcare-associated infections (HAI) affect millions of people around the globe. While the most common cause of HAI is direct contact with the source, airborne bacteria may also play a role in patient infections. To prevent airborne infection and make hospital clean rooms safer, it’s important to design efficient ventilation systems. As an added benefit, efficient ventilation designs also lead to lower energy-related costs. The first step to a better design is CFD modeling.

During the discharge of a battery, the current in the circuit flows from the positive to the negative electrode. According to Ohm’s law, this means that the current is proportional to the electric field, which says that current flows from a positive to negative electric potential. But what happens inside the battery? Does the current flow from negative to positive electric potential? This blog post explains the potential profile inside a battery during discharge and recharge.

When developing a new product or functionality, the first step is typically to understand the functional properties in isolation. To achieve reliable and accurate predictions via mathematical modeling, it is essential that the critical components, test setup, and boundary conditions are specified in great detail. Most engineers, however, would prefer to focus on the critical components rather than “irrelevant” boundary conditions. New impedance boundary conditions in the Acoustics Module of COMSOL Multiphysics help to close this gap.

In structural mechanics, you may want to specify user-defined material models in your simulation. COMSOL Multiphysics® software version 5.2 enables you to access material models derived from external libraries as well as material functions programmed by yourself. We demonstrate how the new functionality works with the example of implementing Mazars’ model to describe damage to concrete.

Many different tools are available for counting particles. Choosing the optimal method depends on the application; specifically, whether you want to use the number of counted particles in equations or during postprocessing. The Particle Tracing interfaces in COMSOL Multiphysics feature three main particle counting options. While these approaches are versatile enough to compute quantities such as charge density and momentum flux, our focus here will be computing the number of particles on a set of domains or boundaries.
