# automatic

Automatically configured speed limit, which limits particle displacement per time step to reduce self-collision tunneling. The limit is proportionate to the particle density of the simulation; a higher density produces a more aggressive speed cap.

## Declaration

```swift
static var automatic: ClothSimulationComponent.SpeedLimit { get }
```
