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™.

If you are in the process of learning how to build simulation apps, the video shown here is a fantastic introduction to writing methods. With a fully functioning app already built, we create a method with the click of a button and then proceed to play a sound, include user inputs, and add an if-else statement. All of this is done using Language Elements, which are included in the Method Editor to help make creating methods a breeze.

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.

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.

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.

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.

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.

Modeling geometries with high aspect ratios can be one of the more challenging tasks for the finite element analyst. You want to have a mesh that will accurately represent the geometry and the solution, but you do not want too many elements, as solving your models would then require excessive computational resources. Here, we will look at using swept meshing to generate efficient and accurate finite element meshes in the context of some common modeling cases.
