Hi Bob,
even though Vensim is really good in solving automatically the system of differential equations "behind" a system dynamic model and in hiding the complexity of a model, can you give me some highligths about the methods Vensim uses for solving the systems? I think it's really a system of differential-algebric equations as we can combine both in a system dynamic model. Can you advice some introductory textbook or papers on that?
Many thanks in advance
Giovanni
