Configuring Runs¶
A scenario brings together your inputs and simulation parameters into a runnable configuration.
Scenario settings¶
| Setting | Description | Default |
|---|---|---|
| Duration | Simulation time in seconds | Required |
| Resolution | Base mesh triangle size in metres | Required |
| Simplify Mesh | Use adaptive mesher for mesh generation | false |
| Max RMSE Tolerance | Error tolerance for adaptive mesher | 1.0 |
| Model Start | Simulation start time (for time-varying inflows) | 1970-01-01 |
How to run¶
- Open a project and navigate to the Scenarios panel
- Select or create a scenario
- Choose the inputs (elevation, boundary, inflow, etc.)
- Set duration and resolution
- Click Run
The simulation is queued and executed on Hydrata's compute infrastructure. Progress is reported as a percentage in the scenario status.
Outputs¶
After a successful run, the following outputs are generated:
| Output | Format | Description |
|---|---|---|
| SWW file | NetCDF | Full time-series of depth, velocity, stage |
| Depth max | GeoTIFF | Maximum water depth at each point |
| Velocity max | GeoTIFF | Maximum flow velocity at each point |
| Depth-integrated velocity max | GeoTIFF | Maximum momentum at each point |
| Stage max | GeoTIFF | Maximum water surface elevation |
Outputs are viewable in the map interface or downloadable for use in GIS software.
