Anyone else with any thoughts on this?

Here is an interesting web simulator, which might answer your questions on simulators.
This is the N-body simulator, which I've used regarding some papers on multiple stars. Fairly easy to use and add parameters too. It runs in Java,
showing effects like interactions, perturbations, relativistic effects, etc.
It might seem rater complex, but it is a useful example of simulations in astrophysics.
