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.
