Commonly used in the automotive industry, snap hooks are a type of fastener that involve the insertion of a hook into a slot. When designing snap hooks, it is important to analyze the forces required for the insertion of the hook as well as its removal. We can address this through simulation.

Lightweight and portable washing machines are great to use in situations where you do not have access to traditional washing machines. Yet problems may occur when a varied distribution of clothing causes walking instability in these machines. We tested for walking instability during the spin cycle of a portable washing machine and used an active balancing method in an attempt to remove this instability.

Often, the most tedious step of finite element modeling is subdividing your CAD geometry into a finite element mesh. This step, usually just called meshing, can sometimes be fully automated. More often, however, the careful finite element analyst will want to semi-manually create their meshes. Although this does require more work, sometimes there are significant advantages in doing so. In this blog entry, we will look at one of the key manual meshing techniques: the concept of geometric partitioning.

The Vivaldi antenna, also known as the tapered slot antenna (TSA), is an ideal antenna for wide-band applications. It stands out due to its uncomplicated structure, simple manufacturing requirements, and high gain. When working on a Vivaldi antenna design, we can use simulation software to evaluate its far-field pattern and impedance.

Try pouring some wine into a glass. Don’t drink it yet — this is a scientific experiment. When you hold up your glass, you’ll see what look like teardrops running down the sides. These tears of wine are caused by the Marangoni effect, which describes a mass transfer along the surface of two fluid phases caused by surface tension gradients along the interface between the two phases (for example liquid and vapor).

Behind the wheel of a car is not the ideal place to discover that the steering wheel is defective. That’s why special precautions are taken during the manufacturing process. The carefully controlled cooling of an injection mold ensures that whatever the product may be, its standards are up to par. Here, we use the Non-Isothermal Pipe Flow interface with the Heat Transfer in Solids interface to study the cooling path of an injection mold for a polyurethane car steering wheel.

We often need to work with experimental data in COMSOL Multiphysics, usually to represent material properties or other inputs to our model. However, experimental data is often noisy; it contains experimental errors that we do not want to introduce into our simulations. In this blog post, we will look at how to fit smooth curves and surfaces to experimental data using the core functionality of COMSOL Multiphysics.
