El defaultSolverIterations determina qué tan preciso los joints (articulaciones) del Rigidbody y contactos de colisión son resolvados. (predeterminado 6). Debe ser positivo.
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).
Este valor usualmente se cambia en el inspector Edit->Project Settings->Physics
en vez desde scripts.
Nota: Cambiar el defaultSolverIterations no afecta a Rigidbodies ya creados. Para cambiar un Rigidbody existente, por favor utilice Rigidbody.solverIterations.
