**"Source terms and propagation" – Uses wind input if provided. **"Propagation only" – Neglects wind input in calculation. *Current interaction – Option to define currents for the simulation.

- "None" – No current interaction will be in the simulation.

Source Material

Source Terms – Specifies whether STWAVE should generate waves using wind and the input spectrum or whether to use the wave spectrum.

Boundary Control

The Boundary control tab contains options for assigning spectral data for the model run.

Source – Select the source for the external boundary conditions
- "Spectral Coverage" – Uses the spectral coverage in the simulation for all boundary conditions.
- "None" – Requires that energy spectra be entered.
Interpolation Type – Sets the method for (CMS-Wave??) to use when interpolating between spectra.
- - "Average spectra" –
  - "IDW interpolation" – Sets the type of data interpolation to Inverse Distance Weighting

Computational Spectral Grid – Adjust and view data related to the computational spectral grid.
- Frequency Distribution – Adjust the Frequency Distribution settings for the computational spectral grid.
  - Number – Adjust the number of frequency bands.
  - Delta – Adjust the step size in Hz.
  - Minimum – Adjust the minimum frequency in Hz.
- Angle Distribution – View the Angle Distribution settings for the computational spectral grid.
  - Number – View the number of angle bands.
  - Delta – View the step size in degrees.
  - Minimum – View the minimum angle in degrees.

Sides – Specified when using a spectral coverage source. The types of boundary conditions include:
- "Specified spectrum" – Click Select to the right to open a dialog box to assign the spectral coverage to the boundary.
- "Zero spectrum" – The boundary doesn't have any spectral energy applied.
- "Open lateral boundary" –

Case data – Defines the time step or cases that will be used and the input boundary conditions for each.
- Wind direction angle convention – Set the convention for the wind direction field for the model.
  - "Cartesian" – The direction FROM. The origin (0.0) indicates the direction is coming from North. It increases clockwise from North (viewed from above). This is most commonly used for wind direction.
  - "Meterologic" – The direction TO. The origin (0.0) indicates the direction is going to the North. It increases clockwise (like a bearing) so 45 degrees indicates a direction heading towards the North East.
  - "Oceanographic" – The Cartesian coordinate axes as a direction TO. East, or the positive X axis, defines the zero direction. It increases in a counter clockwise direction or righthand rule. 45 degrees indicates a direction heading to the North East and 90 degrees indicates a direction heading to the North.
  - "Shore normal" – "TO" convention based on a Theta(grid) which defines the grid orientation relative to the positive X axis (CCW direction).
- Populate from Spectra – Click the Populate button to import data from the (Spectral coverage???).
- Set Reference Time – Click this button to open the CMS-Wave Simulation Reference Time dialog and adjust the reference time and time units.
  - Reference time – Set the desired Reference time for the simulation.
  - Time units – Sets time units for case data to "days", "hours", or "minutes".
- Graphic icons???
- Time – The time offset value representing how much later the time is than the specified reference time. Hence, if 5 is entered for the time offset, and the time units is hours, then it is the case of 5 hours later. When nesting is used, the case ids, and the number of cases, will be determined by the parent simulation.
- Wind Direction – Available if "Constant value" has been selected on the Parameters" tab.
- Wind Magnitude – Available if "Constant value" has been selected on the Parameters" tab.
- Water Level – Available if "Constant value" has been selected on the Parameters" tab.

Source Material

Cartesian: The direction FROM. The origin (0.0) indicates the direction is coming from North. It increases clockwise from North (viewed from above). This is most commonly used for wind direction.
Meteorologic: The direction TO. The origin (0.0) indicates the direction is going to the North. It increases clockwise (like a bearing) so 45 degrees indicates a direction heading towards the North East.
Oceanographic: The Cartesian coordinate axes as a direction TO. East, or the positive X axis, defines the zero direction. It increases in a counter clockwise direction or righthand rule. 45 degrees indicates a direction heading to the North East and 90 degrees indicates a direction heading to the North.
Shore Normal: "TO" convention based on a Theta(grid) which defines the grid orientation relative to the positive X axis (CCW direction).

Sides – Specified when using a spectral coverage source. The types of boundary conditions include:
- "Specified spectrum" – This may come from a parent grid if using nesting. Otherwise, a button to the right will be used to assign the spectral coverage to the boundary.
- "1D transformed spectrum" – This boundary type allows energy to propagate along the boundary without interference. The cells would have the same energy if the grid was extended and the boundary became interior to a larger grid.
- "Zero spectrum" – The boundary doesn't have any spectral energy applied.

Case data – Defines the time step or cases that will be used and the input boundary conditions for each.
- Wind direction angle convention – Controls allow choosing the convention that will be used for the wind direction field in the events spreadsheet. Options include: "Cartesian", "Meteorologic", "Oceanographic", and "Shore normal".
- Time – The time offset value representing how much later the time is than the specified reference time. Hence, if 5 is entered for the time offset, and the time units is hours, then it is the case of 5 hours later. When nesting is used, the case ids, and the number of cases, will be determined by the parent simulation.
- Wind Direction – Available if "Constant value" has been selected on the Parameters" tab.
- Wind Magnitude – Available if "Constant value" has been selected on the Parameters" tab.

Breaking – This will output a dataset representing the wave breaking. For full-plane, this can be no indices (off) or write indices which gives a value of 1 where breaking occurs and 0.0 otherwise. Half-plane has the full-plane options and has an additional option to calculate energy dissipation; this will give a dataset of energy dissipation.

Wind – a constant value or a vector dataset can be used to define the wind for the simulation. If constant is selected, the wind direction and magnitude will be specified in the CMS-Wave Case Definition dialog for each case.
