Have you been interested in learning how to create fillets on 3D designs or how to generate shell approximations of imported geometric objects? The latest version of the COMSOL Multiphysics® software includes the new Design Module, which provides these and other tools for easier and more advanced geometric modeling. This optional add-on also includes interoperability tools for the import and export of CAD designs. Let’s take a look in more detail at what you can do with these new features.

Among its neighboring buildings on the Las Vegas strip, the Vdara® hotel can be identified by its unique crescent-shaped design. While visually appealing, this architectural element became an area of concern as it contributed to the development of a caustic surface on the hotel’s pool deck. As a result, guests at particular locations experienced severe sunburns at certain days and times of the year. Here, we model the generation of a caustic surface in the case of the Vdara® hotel.

The Membrane interface has undergone a number of changes with the release of COMSOL Multiphysics version 5.0. This includes a restructured menu, new feature nodes, improvements to the Linear Elastic Material model, and support for the Hyperelastic Material model. You might remember the Nonlinear Structural Materials model Inflation of a Spherical Rubber Balloon. We have now rebuilt it using the Membrane interface. I will discuss these changes and the new model in today’s blog post.

Here’s a question for all you electromagnetics-focused simulation engineers out there: Have you ever looked in envy at your structural, fluid, and chemical counterparts as they mesh their models with the click of a button, while you struggle to mesh your infinite elements or perfectly matched layers? Well, now you too can enjoy automatic meshing with a click (or two). Let me show you how.

When you think of evaporation, you probably think of the cup on your desk that spreads the aroma of coffee or tea. But evaporation is also a process with many industrial and scientific applications, ranging from meteorology to food processing. This blog entry is the beginning of a new blog series on modeling evaporative cooling. Here, we introduce the basic concepts using your coffee cup as an example.

When the Newtonian telescope was first developed in 1668, it was recognized as the earliest operating reflecting telescope. With its low cost and simplistic design, this optical system became a favorable alternative to refracting telescopes, and the technology continues to be widely used today. Using the Ray Optics Module, we can analyze ray propagation within this type of telescope system.

Bright light-emitting diodes (LEDs) are revolutionizing the lighting industry and blue LEDs in particular are ushering in a new age of widespread efficient LED lighting. The importance of blue LEDs was marked by this year’s Nobel Prize in physics, which went to the inventors. But, because bright LEDs are driven by larger currents, they suffer from reduced efficiency — a phenomenon known as LED droop. Using multiphysics simulations, we can investigate and understand the mechanisms behind LED efficiency.

We just launched a new app for you to download from the Application Library update. This app is a dedicated tool for modeling the flow and pressure distribution inside a network of connected pipes. Engineers in semiconductor processing could use a tool like this to test a given design and ensure it will meet specification before prototyping the physical device. Here, I’ll give you some background info and walk you through how this app works.

In the previous installment of the postprocessing series, we showcased techniques for visualizing results on cross-sectional slices. Now, we’ll discuss how contour and isosurface plots can be used to show quantities on a series of lines or surfaces. Though they’re usable in many applications (from heat transfer to acoustics), we’ll specifically look at how they can show mechanical stress in a driving pulley and sound pressure levels in a loudspeaker.
