The solverIterations determines how accurately Rigidbody joints and collision contacts are resolved. Overrides Physics.defaultSolverIterations. Must be positive.
If you are having trouble with connected Rigidbodies oscillating and behaving erratically setting
a higher solver iteration count may improve their stability (but is slower).
