This seems interesting. I teach circuits and networks every semester as an application of ODEs/systems of ODEs. The EMF is not necessarily constant and occasionally we might have a variable term (eg, a variable capacitor). Questions:
1. Does his program allow non-constant terms and symbolic terms? 2. How does it draw circuits? (I use Dia now for cicuits in lecture notes and exams but his circuits look nicer, IMHO.) 3. Are there any examples of an output (eg, given a parallel circuit with a capacitor, EMF, resistors and inductors, can it find the charge on the capacitor as a function of t)?
