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.

Vivaldi Antenna Design Analysis

Caty Fairclough March 25, 2015

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.

Tears of Wine and the Marangoni Effect

Brianne Costa March 24, 2015

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).

Simulating Injection Mold Cooling

Brianne Costa March 23, 2015

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.

Modeling with Linearly Polarized Plane Waves

Bridget Cunningham March 20, 2015

COMSOL Multiphysics version 5.0 introduced users to a new background field feature designed for linearly polarized plane waves. Explore the use of this new feature with an example of polarization-dependent scattering from our Model Gallery.

Curve Fitting of Experimental Data with COMSOL Multiphysics

Walter Frei March 19, 2015

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.

Want to share your simulations with the world or simply your own team? After you build an application with the Application Builder in the COMSOL Multiphysics® software, you can share your app using a COMSOL Server™ license with anyone from colleagues to customers. Here is your introduction to COMSOL Server™ — what it is, why to use it, and a brief overview of how to get started.

Exploring the Natural Strength of Limpet Teeth

Bridget Cunningham March 16, 2015

A recent study from researchers at the University of Portsmouth has deemed limpet teeth as the strongest biological material known today. We shed light on the unique properties of this material and how it compares to its predecessor: spider silk.

Using Simulation to Optimize Biopharmaceutical Processes

Bridget Cunningham March 13, 2015

The biological and chemical processes behind the development of biopharmaceuticals have an important effect on product quality. With its ability to deliver quick results at a lower cost, simulation is a valuable resource in studying and optimizing these techniques. Learn how COMSOL Multiphysics can benefit your modeling of biopharmaceutical processes.

Happy Birthday, Gustav Kirchhoff

Brianne Costa March 12, 2015

Gustav Robert Kirchhoff was a German physicist famous for his vast contributions to the study of spectroscopy, electrical circuits, thermochemistry, and more. Kirchhoff developed laws and theories fundamental to electrical engineering, heat capacity in chemical reactions, and the composition of light emission from incandescent objects. He even helped discover two new elements! In honor of what would have been his birthday, here is a look at Kirchhoff’s legacy.
