Automatically Handling Selections in COMSOL Multiphysics®

July 2, 2014

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.

How to Join Solutions in COMSOL Multiphysics

July 1, 2014

In engineering analysis, the need to compare solutions obtained under different circumstances frequently arises. Some possible scenarios include comparing the effect of different load or parameter configurations, and enveloping results to find the worst or best case at each point of the domain. In each of these and other similar cases, you need access to more than one data set. Here’s how to accomplish such tasks using COMSOL Multiphysics.

FIRST® Robotics at PTC® Live Global 2014

June 30, 2014

A couple of weeks ago, we exhibited at PTC® Live Global. In addition to manning the exhibition booth and learning about PTC® Creo® Parametric™ 3.0, we were introduced to a fantastic program called FIRST®, which gets kids involved in science and technology.

Getting the Most out of Client-Server Mode

June 27, 2014

When using COMSOL Multiphysics on a Floating Network License, it is possible to use the Client-Server mode of operation to access remote computing resources for solving large models, while still using the graphics card on a local machine to display graphics. This can have some significant advantages, so let’s look at Client-Server mode in more detail.

Studying Sonar Systems on a Component Level

June 26, 2014

Sound Navigation and Ranging (SoNaR, more commonly written in all lowercase as “sonar”) technology can be used for investigating and communicating underwater. To improve the sonar system, you need to optimize the design at a component level. A major component of sonar is the electro-acoustic transducer.

Seas of Change for Wind Turbines

June 25, 2014

Wind turbine noise is a (hotly disputed) topic that we’ve mentioned on the blog before. While research into noise production by wind farms is still being debated among researchers, one way we’ve found to overcome these noisy turbine troubles is to place turbines offshore where they can’t be heard and, conveniently, high winds with more regularity make energy production more effective. However, a question that comes to mind is: What impact do offshore wind farms have on marine life?

Portable Cordless Vaccine Storage Device

June 24, 2014

The Passive Vaccine Storage Device (PVSD) is a highly advanced container that combines ingenuity and insulation technology to empower aid workers delivering vaccines to the toughest-to-reach corners of the globe. Designed as a prototype that improves upon earlier models of vaccine transportation devices, this compact apparatus was developed with all the necessary steps: careful planning, simulation, and testing.

Modeling Convective Cooling of Electrical Devices

June 23, 2014

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.
