Scenarios

A project may contain any number of scenarios. Scenarios allow comparison between different environmental situations, sources, mitigation, grids, and solvers. Each scenario is independent and contains its own:

Sources (positions, spectra, movement)
Receiver area and grid resolution
Probes
Environmental properties (water column sound speed, seabed layers)
Frequency weighting
Solver and frequency selection
Calculated results

Bathymetry, geographic setup (UTM zone, coordinate system), and GIS overlays are shared across all scenarios.

Managing Scenarios

Use this page to add, delete, or duplicate scenarios. The scenario table shows all scenarios with their status:

Activate — click to switch to a scenario
Solve — toggle whether a scenario is included in batch solving. Disabling a scenario keeps any existing results
Levels — indicates whether calculated results exist

Each scenario has an editable name and a comments field for notes.

Duplicating a scenario creates a full copy of all settings and any calculated results. This is useful for parameter studies where you want to change one variable while keeping everything else the same.

Removing results clears the calculated levels from a scenario without deleting the scenario itself. This frees memory and allows re-solving with different settings. Use the Remove current scenario levels button, or right-click a scenario for options.

At least one scenario must always exist in a project.

Comparing Scenarios

The Summary button opens a side-by-side comparison table showing key settings for all scenarios — solver configuration, frequency range, grid resolution, sources, probes, and more. This table can be copied to the clipboard.
