Veryst Combines Material Testing and Simulation for Reliable Results

Fanny Griesmer March 11, 2019

Success in today’s marketplace comes down to both developing reliable products that work as intended and launching them at the right time. Like many other companies out there, Veryst Engineering has found that simulation is an effective tool for looking inside a product and ensuring that the design meets specifications prior to prototyping or manufacturing. For this to work, simulations have to match real-world responses, and understanding material behavior plays a central role. However, not all materials behave predictably.

Charge exchange cells can alter the charge of an ion beam, making them useful in fusion reactors, particle accelerators, and semiconductor fabrication equipment. Improving the design of these devices, though, can be time consuming, as many factors (like the input beam’s energy, cell geometry, and neutral number density) affect their performance and must be tested. While these analyses are typically done by simulation experts, they can make the design of such devices accessible to others by building a simulation application…

Industry 4.0 and digital twins are buzzwords we hear on a daily basis. But how far have companies come, and how does COMSOL come into play in the new era? Here, we will look into one successful case, where ABB Traction Motors intends to make mass customization available by using simulation applications for electric motor design. By turning high-fidelity multiphysics models into simulation applications, new analysis capabilities are planned to be available to several departments, from product design to sales.

Cables provide power to sky-high airplanes, underground mines, and offshore wind farms. Depending on the use case, cables can have vastly different shapes, sizes, and environments — all of which affect their performance. In his keynote talk at the COMSOL Conference 2018 Lausanne, Adrien Charmetant of Nexans explained how multiphysics modeling is used to optimize cable designs. Below, you can find a summary and video of his presentation.

The EPFLoop team took the stage at the COMSOL Conference 2018 Lausanne with their hyperloop pod design, setting it down for the crowd to see. Learn about the different ways that the team of students and faculty from the École Polytechnique Fédérale de Lausanne, led by Mario Paolone and including Nicòlo Riva, Zsófia Sajó, and Dr. Lorenzo Benedetti, used multiphysics simulation to land in the top spot for hyperloop design at the 2018 SpaceX competition.

In a fluid-structure interaction (FSI) scenario, the fluid can affect the structure, the structure can affect the fluid flow, or both. When modeling a device that relies on FSI, you may want to simulate one of these options, a combination, or all three. The Fluid-Structure Interaction multiphysics coupling in the COMSOL® software makes it easy to implement FSI in your analyses. In this blog post, we study the flow through a ball check valve for different flow directions and pressures.

The goal of mesh adaptation is to modify the mesh to solve a problem more efficiently. We want to use as few elements as possible to obtain an accurate solution. Typically, we would like a coarser mesh in regions that are not very important and a more refined mesh in regions of interest. We might even consider anisotropic elements. As of version 5.4, the COMSOL Multiphysics® software includes enhanced tools to adapt a mesh. Let’s take a look.

Radioactive materials have a long half-life, so they must be stored safely — usually in steel drums. These drums are then stored in confinement systems, which are designed with safety in mind (so that they can resist, for instance, a fire event exceeding two hours). Sogin, the state-owned company responsible for the Italian nuclear sites decommissioning and radioactive waste management, evaluated the fire resistance of a confinement system overpack using the COMSOL Multiphysics® software.

Groundwater is an important source of irrigation and drinking water, so keeping it pure is crucial. However, once contaminants get in, it isn’t so easy to get them out — creating systems to remove contaminants from groundwater requires an understanding of the complex way immiscible fluids move through soil. To gain insight into this behavior, engineers can use the phase transport functionality in the COMSOL® software.

Until the early 1900s, shock waves were an academic problem studied from a theoretical point of view only. Many great scientists, including Lord Rayleigh, worked on the field until the theory of inviscid shock waves was established in the 1920s. During World War II, this theory started to be applied, mostly to supersonic vehicles. To study shock waves, one important gas dynamic instrument is the shock tube, which is used to test supersonic and hypersonic flows and high-temperature gases.

Heart failure is a global health concern, affecting millions of people and keeping them from their everyday lives. But what if there was a device that could keep patients’ hearts pumping and even improve their quality of life? In his keynote presentation at the COMSOL Conference 2018 Boston, Freddy Hansen from Abbott Laboratories discussed a heart pump that could do just that. If you missed his talk, you can watch a recording of the video and read a summary below.
