Hello, Dear Circuit Lab stuff! I am in awe with what I see, it is very innovative, cool and well done, but I think an important feature is missing - the ability to calculate the energy dissipated in a component over time. The power in Joules should be the integral of the power in watts over time in seconds (yeah, sorry for my bad math if it really isn't). The thing with Joules is that in power electronics it should help determine the reliability of the element, for example when switching inductive loads. I would also like to have a glimpse of the total energy dissipated by my Xenon flash simulation attempts:

This shows a way to calculate and plot the energy delivered to a load:

For background on why the ustep() is of the form:

ustep(T-1p)

and not simply:

ustep(T)

For background on why the Laplace integrator is of the form:

1/(s+1p)

and not simply:

1/s

Cool. Thanks, it works well. The behavioral sources are a pretty neat feature too.
