Providing the Littoral Processes FM module with a suitable domain helps the setup as the bathymetric description (using lines and points) can be visualised within a 2D environment.
You may specify the domain either explicitly by defining the map projection and the extension of the area, or you can specify a 2D mesh bathymetry file, by which the map projection and enclosure will define the domain area.
The geographic view in the setup dialogs will per default display the defined domain area, but you have access to zoom and pan functionality via right-click in the display.
If you have specified the domain from a 2D mesh bathymetry file you will later have the option to extract bathymetry data from the mesh bathymetry for use in the calculation.
The selected map projection defines the projection of the output. Having a different map projection in data files (e.g. the cross-shore profile) may lead to unexpected results.
The LONG/LAT map projection is only applicable for the model type “Transport in point”.
