How to solve an ODE in COMSOL Multiphysics

I plan to show you how to model a magnet falling through a copper pipe. To do this, we first need to learn how to solve an ODE in COMSOL and how to perform a moving mesh analysis. In this video, I show how to implement a general ODE in COMSOL. Using this, we can perform the moving mesh study in the next video, which will prepare us for modeling a falling magnet.
