  1. 1

    Although titled “all about”, this overview left me with some questions:

    • How can I run the code samples?
    • How can I see outputs of the simulation? How can I get the promised answers from the simulation?
    • How are nonlinear systems modelled?
    • What are the weaknesses of Modelica? When are other simulation approaches more appropriate? The article has a relentlessly promotional tone. How does it compare to other systems that I have used like Spice or VisSim or MathCAD?
    • In the RC example, suppose I want to add another resistor in parallel with the existing one. It is not at all obvious how this would be accomplished in the example code. Would this require at additional model for an electrical junction that encodes KCL? Or is there some magic in the unexplained flow keyword?
