Hi,

I would like to use system modeller to simulate physical experiments for my
studies. One example would be to derive the gravitational constant for an
Earth-bound system from the oscillations of a simple pendulum. I have been
reading in the book from Peter Fritzson: "Introduction to modelling and
simulation of technical and physical systems with Modelica" and from what I
understand this approach to modelling an experiment could be referred to as
inductive modelling.

Obviously, there seems to be a Catch-22, as the pendulum won't oscillate
unless we define the gravitational constant in the first place ..

I would like to hear some opinion about how to go about working with system
modeller to the end of replicating physics class experiments in a virtual
environment.

Regards

Berthold Hamburger
