The defaultSolverVelocityIterations affects how accurately the Rigidbody joints and collision contacts are resolved. (default 1). Must be positive.
Increasing this value will result in higher accuracy of the resulting exit velocity after a Rigidbody bounce.
If you are experiencing issues with jointed Rigidbodies or Ragdolls moving too much after collisions you can try to increase this value.
Este valor usualmente se cambia en el inspector Edit->Project Settings->Physics en vez desde scripts.
Nota: Cambiar defaultSolverVelocityIterations no afecta los Rigidbodies ya creados. Para cambiar un Rigidbody existente, por favor utilice Rigidbody.solverVelocityIterations.
