# stability_control Section

This section configures **stability control parameters**, including **CFL ratios**, **subcycling**, and **instability checks**.

---

 | **Parameter** | **Description** |

 | `Max_Delta_Currents` | Maximum delta currents for stability (default: `4.0 m/s`). |
 | `Max_Delta_Period` | Maximum delta period for stability (default: `3600.0 s`). |
 | `maximum_admissible_elevation` | Maximum admissible elevation for stability (default: `20.0 m`). |
 | `persistence` | Persistence duration of previously unstable nodes in subcycling (default: `6.0 hours`). |
 | `SubcyclingTemporization` | Maximum successive subcycling reprocessing (default: `10`). |
 | `SubcyclingExtension` | Minimum neighbor band between subcycle mesh limits (default: `5`). |
 | `SubcyclingLockLimit` | Lock limit for unstable nodes (default: `5`). |
 | `CFL_min_depth` | Minimum depth for CFL (default: `4.0 m`). |
 | `CFL_depth_offset` | Depth offset for CFL (default: `0.0 m`). |
 | `CFL_velocity` | Velocity for CFL (default: `0.0 m/s`). |
 | `ArchiveSubcyclingMesh` | Flag to archive subcycling mesh (`TRUE`, `FALSE`). |
 | `ArchiveSubcyclingLevels` | File for subcycling levels archive. |
 | `ReloadSubcyclingLevels` | File for subcycling levels reload. |
