As long as these are your stated objectives I certainly can't take any issue with them. In fact, I qualified my statement with "I don't know your ultimate goals" for precisely this reason. Without knowing your goals I certainly can't made a valid argument about your approach. I am glad that you appear to have understood the spirit of the comment. If you ever do decide to consider larger scale models, you might want to look into "OpenModelica" (an open source implementation from Linkoeping University). It includes a compiler that can take Modelica code and generate "flat Modelica" (processing inheritance, hierarchy, replaceable components, etc. down to just variables and equations). One final note on perspective. The main driver for my comment is that I am an industrial user but I would love to have these kinds of analysis capabilities. I see that as one of the remaining opportunities in Modelica (i.e. the ability to build niche analysis capabilities, which commercial vendors perhaps could not justify, around a standard description). Having it done within a Python framework would be icing on the cake. :-) > Rob -- Mike -- http://mail.python.org/mailman/listinfo/python-list
