I just bought NODAL and it looks good if you really want to simulate electronic circuits. My purpose, however, was to use Nodal in the same way some os us have used PSpice for years, namely as a general purpose simulator for generalized flow problems, network thermodynamics, compartmental analysis, chemical reaction networks, etc. It turns out that Nodal is ill- adapted for this kind of work, because the key feature that makes Spice (and PSpice is even better) good for this is the possibility to define nonlinear voltage- or current-controlled sources with any constitutive relation you want. Nodal includes only linear-first order controlled sources, which hobbles it completely for our purposes. Perhaps there's a workaround that I haven't found, yet, since I've only had it two weeks. If so, I'd be happy for the help. Randall Thomas
