Using Simulation in the Race Against Corrosion

Lexi Carver December 28, 2015

Corrosion is one of the most serious factors affecting the transportation industry. In an effort to minimize its impact, a German research institute and the manufacturers of Mercedes-Benz joined forces to investigate the corrosion occurring in automotive rivets and sheet metal. Using COMSOL Multiphysics simulation, they were able to study corrosion’s effects on car components.

In this blog post, we will introduce the concept of shape optimization for adjusting part dimensions by using analytic sensitivity methods. If you have a single objective function that you want to improve, a set of geometric parameters that you want to change, as well as a set of constraints, then you can use the functionality of the Optimization Module and the Deformed Geometry interface in COMSOL Multiphysics to find the optimal structure without any remeshing. Let’s find out how!

3D printing, also known as additive manufacturing, has been a popular topic of discussion on the COMSOL Blog and throughout the scientific community. New initiatives have furthered the capabilities of this technology, while extending its reach in various fields of research, manufacturing, and design. With the help of COMSOL Multiphysics, researchers at the Netherlands Organization for Applied Scientific Research (TNO) are investigating the promise of 3D printing in the realm of material design.

After recently encountering the equations of motion for rotating bodies for the first time, one of my sons came home with a number of interesting questions. His questions brought about a flashback, as I remembered sharing this sense of confusion when studying mechanics many years ago. In today’s blog post, I will present two COMSOL Multiphysics models — one of a gyroscope and one of a spinning top — that illustrate the remarkable properties of rotating bodies.

Reinforced concrete beams are commonly used in modern construction due to their strength and durability. To avoid failure, each new beam design needs to be optimized and tested for safety. Building physical prototypes to test every design modification can be a long and costly endeavor. Simulation apps offer a solution, saving time and money as they bring simulation power into the hands of more people. Explore the benefits of this approach with our Parameterized Concrete Beam demo app.

In COMSOL Multiphysics version 5.2, the CFD and Microfluidics modules include a new fluid flow interface for modeling separated three-phase flow. The model behind this fluid flow interface accounts for surface tension between each pair of fluids, contact angles with the walls, as well as the density and viscosity of each of the fluids. The phase field method computes the shape of the interfaces between the three phases and also accounts for interactions with walls.

The demand for better performance and increased accuracy in touchscreen devices is growing. Simulation, a fast and cost-effective approach to product development, helps to meet this goal. With each design modification, colleagues will typically rely on you to run simulation tests, awaiting your feedback before reaching out to customers. As researchers at Parade Technologies (formerly Cypress Semiconductor) have discovered, creating apps and distributing them to colleagues is a valuable way to save time and more effectively communicate with customers.

When the loudspeaker was first introduced, it fascinated listeners by translating electricity into amplified sound. Since that time, the device continues to be recognized for its innovative properties, while undergoing improvements and finding new uses. On this day, which marks 100 years since the first public display of a loudspeaker, we explore the device’s rich history and simulation’s role in advancing its design.

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.
