Evaluating an Insulin Micropump Design for Treating Diabetes

July 21, 2016

In any form of treatment, it is always desirable to minimize the level of discomfort that the treatment process causes patients, while ensuring overall safety and effectiveness. For diabetes patients, insulin injections remain an important form of treatment, but the process itself can be painful. With the help of multiphysics simulation, a team of researchers from the University of Ontario Institute of Technology sought to develop a MEMS-based micropump that could administer insulin injections in a safe and painless way.

Using the Application Builder as a Tool for Teaching Students

May 19, 2016

Maximizing the efficiency of the learning process while keeping students engaged is the common goal that professors hope to achieve in any course. In the realm of physics- and engineering-based courses, simulation apps are helping to strike such a balance by introducing students to complex concepts in a simplified format. Here, we’ll take a look at some of the innovative ways that university professors are utilizing apps within the classroom.

Control Current and Voltage Sources with the AC/DC Module

February 25, 2016

If you’ve ever worked with the Terminal boundary condition in COMSOL Multiphysics, you know that this electrical boundary condition can apply a current or voltage, among other options. But did you know that you can also dynamically switch between excitation types during a transient simulation? This is useful if you are trying to model a current- or voltage-limited power supply, for example. Today, we will look at how to implement such a switching behavior.
