Auguri & congratulations !

The tube amp example is really nice - including the interaction 
with the speaker - all of it: electrical, mechanical and acoustic. 
This is also the first time I see both the impedance and mobility 
models explained in a graduation paper. The fact that the two
exist is the source of *lots* of confusion - you did well to
include this, even if it's just a detail in the whole paper.

A question: how many iterations does the tube model typically
require to converge to the required precision ?

I hope you will continue to develop Permafrost, even without
optimisation it would make a very nice simulation tool.
