SMS:STWAVE Menu

The items in the STWAVE menu in the Cartesian Grid Module are described below:

• Spectral Energy – opens the Spectral Energy dialog.
• Assign Cell Attributes – opens the STWAVE Cell Attributes dialog.
• Model Control – opens the STWAVE Model Control dialog.
• Run STWAVE – launches the finite element analysis engine.

Cell Attributes

STWAVE Cell Attributes

The STWAVE Cell Attributes dialog is used to assign a cell type to selected Cells. It is opened using the menu command STWAVE | Assign Cell Attributes. The following cell types can be assigned:

Default

Cells are no longer assigned as Land or Ocean types but are assigned as Default where their elevation values are used to simulate whether flow exists or not. If no elevation data is available for part of the grid area, it is important to specify an extrapolation value of a negative number. Extrapolation values can be specified in the Interpolation dialog while doing Map → 2D Grid.

Monitoring Station

Spectral output is generated for cells designated as monitoring station cells.

Nesting output

Spectral output is generated for nesting output cells cells to be used as input for a nested child grid.

Displaying Cell Attributes

The symbols and colors used to identify the attributes assigned to cells can be changed in the STWAVE Display Options.

Run STWAVE

After a simulation has been read or saved, SMS can launch the finite element analysis engine. To run STWAVE:

1. Select STWAVE | Run STWAVE. A dialog appears showing the engine that will execute.
2. If the executable program is the wrong version, or if you are given the message that it was not found, then click the file browser icon and choose the correct version of the program that should run.
3. Click the OK button or press the ENTER key.

A window will appear which displays various information as STWAVE runs. You should not need to type anything in this window. If the window prompts you for filenames, you need an updated version of the STWAVE model executable. When STWAVE has finished, you will be prompted to press the ENTER key. If the window goes away before doing this, STWAVE encountered a problem and crashed.
