Thanks Christopher! I'm not sure how I missed the demos, but the LorenzDifferentialSystem is exactly what I was looking for.

The docs for the Ptolemy DifferentialSystem actor may be found at http://chess.eecs.berkeley.edu/ptexternal/src/ptII/doc/codeDocViptos/doc/codeDoc/ptolemy/domains/continuous/lib/DifferentialSystem.html There are these demos that might help: * ptolemy/domains/gr/demo/FurutaPendulum/FurutaPendulum.xml * ptolemy/domains/continuous/demo/FurutaPendulum/FurutaPendulum.xml * ptolemy/domains/continuous/demo/Lorenz/LorenzDifferentialSystem.xml _Christopher On 10/21/13 4:42 PM, Godbole, Pranav wrote: Hi! I'm looking to solve a sizable number of 2nd order ODE's in Kepler. Given the large number of equations I need to solve, I think using the standard 'expression / integrator' method may become too messy, so I was looking into using the Differential System actor to keep things tidy. The problem is I'm not sure how to correctly use the actor. I found the documentation to be confusing and could not find any tutorials for Kepler/Ptolemy II/Simulink to clarify. If someone could write a quick tutorial using a minimal example (maybe an undamped pendulum) or point me in the right direction, I would greatly appreciate it! Aside: The ODE's are in reduced (1st order) form, so it is really just a matter of getting it into Kepler.
