There are two aspects of home brewing: the culinary side and the engineering one. Many beer lovers start brewing either to improve a recipe, try to clone their favorite beer, or even simply just to see how it works. After brewing a few batches, however, it turns out that the brewing process can also be very challenging from an engineering point of view.

Billions of dollars are spent each year in the U.S. to repair corrosion damage. To help reduce the high cost of corrosion, engineers at the Naval Research Laboratory (NRL) in Washington, D.C. are using multiphysics simulation to gain a better understanding of the fundamental mechanism. A successful research outcome at NRL will establish the correlation between metal microstructure, corrosion, and mechanical strength. Material designers could then develop stronger, corrosion-resistant materials using this new information.

In the 2012 edition of Multiphysics Simulation, we featured an article about modeling spinal cord stimulation to determine the effect that scar tissue can have on electrical current distribution during the treatment of chronic pain. Recently, the full-length paper by Beth Israel Deaconess researchers Jeffrey Arle, Kris Carlson, Longzhi Mei, and Jay Shils was published in the journal Neuromodulation.

In order to carry astronauts safely beyond earth’s atmosphere to where they can explore outer space, spacecraft must provide a very important chemical mixture: breathable air. Given the limits on space and weight for a manned shuttle, the systems flying aboard the craft must revitalize the air inside rather than carry the full amount needed for a mission. With this in mind, a team at NASA has developed an approach to atmosphere revitalization that relies on water adsorption.

This is Part 3 of a blog series on how to handle selections and entity numbers when using LiveLink™ for MATLAB® and the COMSOL® Application Programming Interface (API). In this section, I’ll discuss how the internal handling of selections and entity numbers in COMSOL Multiphysics® simulation software is performed and how you can utilize these methods when setting up your own models.

One of the main issues with high-power electrical devices is thermal management. Together with BLOCK Transformatoren-Elektronik GmbH, we created a model using COMSOL Multiphysics simulation software that encompasses all of the important details when modeling heating of high-power electrical devices. To do so, we had to utilize high performance computing (HPC) with hybrid modeling. Here, we will discuss how to approach this real-life task with the COMSOL software.

In Part 1 of this blog series, I introduced how you can export a model M-file from COMSOL Multiphysics® simulation software to learn about the structure of the COMSOL Application Programming Interface (API). One important part of a model M-file is the selections that are made in order to set up properties for the domain, boundaries, etc. These selections are identified using numbers. Here, we explain how you can automate the handling of the entity numbers using LiveLink™ for MATLAB®.
