All equations to be solved
The number of solver iterations determines quality of the constraints in the world. The more iterations, the more correct simulation. More iterations need more computations though. If you have a large gravity force in your world, you will need more iterations.
subsolver
When tolerance is reached, the system is assumed to be converged.
