# Adjust Rigidbody component solver iterations

> Adjust solver iteration counts for a Rigidbody component to improve simulation accuracy.

Adjust solver iteration counts for individual Editor components to improve simulation results.

If a specific **Rigidbody** component in your scene requires higher simulation accuracy or stability, such as preventing jittering in stacks or ensure joint stability, adjust its solver iteration count individually. Increasing solver iterations uses more CPU time for that specific **Rigidbody** component. This targeted approach is more efficient than increasing the global solver iteration count, which would affect all **Rigidbody** components.

To adjust the solver iterations for a specific **Rigidbody** component, use [`Rigidbody.solverIterations`](/engine/6000.6/script-reference/unityengine/rigidbody/solveriterations.md) on that specific component. This setting overrides the global project setting for that **Rigidbody** component only.

To configure the global setting for all **Rigidbody** components in your project:

1. Select **Edit > Project Settings** to open the Project Settings window.
2. Select the **Physics > Settings** tab.
3. Select the Editor tab.
4. Adjust the **Default Solver Iterations** value.
