Göttingen, a University Town with a Rich Scientific History

Bridget Cunningham September 25, 2015

Göttingen, Germany, a city located in the valley of the Leine River, is home to one of our COMSOL branch offices. Recognized as a university town, the city features a vibrant and youthful atmosphere, with an emphasis on freedom in scientific research and exploration. Let’s take a closer look at the history of Göttingen’s prestigious university — the University of Göttingen — and learn more about the character and feel of the city.

In an operating nuclear reactor, complex and highly coupled physical phenomena occur. Analyzing such phenomena within these devices by conducting physical experiments is often difficult and sometimes impossible. Simulation offers a simplified approach to studying and optimizing nuclear reactor designs, saving time, money, and other resources.

Think about the first architects who designed a bridge above water. The design process likely included several trials and subsequent failures before they could safely allow people to cross the river. COMSOL Multiphysics and the Optimization Module would have helped make this process much simpler, if they had computers at the time, of course. Before we start to discuss building and optimizing bridges, let’s first identify the best design for a simple beam with the help of topology optimization.

The Application Builder and the COMSOL Server™ license have changed the way simulation engineers develop a project — from research and design to testing and development. If you are wondering how you can use these tools for your own modeling needs, read our list of seven use cases for the Application Builder and COMSOL Server™.

Do you drool at the very mention of chocolate? If so, you’re a “chocoholic” like me, and Nestlé’s Kit Kat® bar is one of my favorites. For 80 years, people around the globe have devoured this four-piece delight. To ensure every bar of chocolate produced has the same consistency, texture, and taste, the engineers at Nestlé’s Product Technology Centre in York, UK (PTC York) are using simulation to optimize the Kit Kat® bar manufacturing process.

Previously on the blog, we introduced you to the constructal law, the law of physics that accounts for the natural tendency of designs to evolve freely over time to flow more easily. As research has been conducted to support this pattern of design evolution, an even greater phenomenon has come to light: Humans and technology are one species, evolving together.

Weight reduction is a key design focus in many applications. This is particularly true in the automotive industry, where lightweight materials help foster the development of fuel efficient cars. Maintaining the structural integrity of these materials is, of course, an important concern. As we will show you today, simulation is a valuable tool for addressing this challenge.

Fluid dampers have a range of uses, from stabilizing skyscrapers to controlling fluid flow in microflow devices. Through a process called viscous heating, these dampers are able to dissipate mechanical energy into heat. Too much heat can cause damage to the damper, so it’s important to understand the viscous heating process when optimizing your fluid damper designs.

Good competitive paddling requires strength, timing, consistency, and teamwork. Initially, this may seem quite easy. Simply stick your paddle in the water and make the water go backward so that the boat moves forward. As it turns out, there are actually many different paddling strokes you can use depending on the situation.

When using the finite element method, we often want to model solid objects that are rotating and translating within other domains. The deformed mesh interfaces in COMSOL Multiphysics can be used to model these movements. In this blog post, we will look at the modeling of large linear translations and rotations of domains within other domains, while introducing efficient modeling techniques for addressing such cases.
