- Open a new project
- Start in Generic Data by defining a Coastline, a Cross-shore profile (a slope, spatially varying bathymetry is optional) and tidal characteristics.
- If required, define breakwater structures.
- Open the Flowfields tool.
- Choose a grid resolution and click on the draw "Draw grid outline" button (). Now, drag a grid extent on the map, while keeping your left mouse button pressed.:
- Press the ("Rotate/move grid outline ( ) button to move and rotate your domain.
- Hold CTRL to rotate your the grid , outline. the blue box indicates the grid extent, while the arrow indicates the offshore direction.
- Hold SHIFT to move your the grid outline, the blue box indicates the grid extent.
- The type of boundary conditions model boundaries can be set within this sectionin the section 'boundary conditions'. You can choose from the following types of boundaries:
- Water levels, defined on the offshore boundary
These are defined by the tidal components from in generic data - Currents, defined on the lateral boundaries
These are defined by the max. horizontal tidal velocities from generic data
- Water levels, defined on the offshore boundary
- Press the delete button to delete the coastlines from the map.
- A spin-up time can be defined (HH:MM:SS format) after which the model will show output on the map
- By pressing the PLAY button <BUTTON>, the simulation is started.
- After completing the spin-up period, the model will indicate the water levels and flow velocities.
- The plotted variables can be changed in the section Visualization
- During the simulation, any breakwater (point) can be moved around by clicking on <BUTTON>
- The interactive flowfields will automatically update
- Note that you can also save your breakwater changes to the generic data (for use in other tools), by pressing the button "Set temporary structures to structures"
- You can interact with the model progress:
- Click <BUTTON> to pause
- Click <BUTTON> to start/resume
- Click <BUTTON> to stop the simulation
- Click <BUTTON> to compute a single timestep
