Physics.defaultSolverIterations

Description

The defaultSolverIterations determines how accurately Rigidbody joints and collision contacts are resolved. (default 6). 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).

This value is usually changed in Edit->Project Settings->Physics inspector instead of from scripts.

Note: Changing the defaultSolverIterations does not affect already created Rigidbodies. To change an existing Rigidbody please use Rigidbody.solverIterations.
