SMS:Spectral Energy

The Spectral Energy dialog can be opened through STWAVE | Spectral Energy, BOUSS-2D | Spectral Energy, CGWAVE | Spectral Energy, or by choosing STWAVE | Model Control, clicking on the Boundary Conditions button to open the Boundary Conditions dialog, and then clicking the Spectral Energy button. The spectrum represents energy densities at discrete values over a range of angles and a range of frequencies for a given wave condition.

Tools

• File:SelectCGridCell.JPG Select Cell Corner - Select a cell corner to view or edit the energy value.
• File:Pan.JPG Pan - Pan the spectral grid.
• File:Zoom.JPG Zoom - Zoom in the window.
• File:Rotate.JPG Rotate- Rotate in the window.
• File:Frame.JPG Frame - Frame, or zoom to the extents of the grid.
• File:Contours.gif Contour Options - Bring up the contour options dialog for setting the spectral grid contour display options.

Grid Options

• Create Grid – Brings up the Create Spectral Energy Grid dialog.
• Generate Spectra - Brings up the Generate Spectra dialog.
• Import Spectra – Brings up the Import Spectra dialog.
• Export Spectra – Brings up the Export Spectra dialog where you can choose a location to save the spectra.

Spectral Tree Options

• Spectral Manager Tree - Select a spectrum in the tree. The selected spectra will be displayed in the Spectral Viewer. The tree’s right-click options are described below.
• Select Spectral Grid – Brings up a dialog to choose a spectrum. Only one spectrum can be viewed at a time. This selects the spectrum to use/visualize. For models that can only use one spectrum, this spectrum will be tied to the model when leaving the dialog (i.e. clicking "Done").

Grid/Spectra Right-click Options

• Generate Spectra – Opens the Generate Spectra dialog. This option is available when the grid in the Spectral Manager Tree is right clicked.
• Edit Spectra – Opens the Edit Spectra dialog where the Parameter Settings, Angle Settings and Spectral Parameters can be edited.
• Export Spectra – Brings up the Export Spectra dialog where you can choose a location to save the spectra.
• Rename Grid or Rename Data Set – Rename a grid or spectrum.
• Delete Grid or Delete Data Set – Deletes a grid or spectrum.
• Properties – Brings up the Spectral Grid Properties dialog. This option is available when the grid in the Spectral Manager Tree is right clicked.

View Options

• Cartesian/Polar View - View and edit the spectral grid using a Cartesian or polar view.

Graphic Options

• Selection - View the Frequency, Angle, and Energy of the selected cell corner. The Energy can be edited for the selected points.
• Cursor - View the Frequency, Angle, and Energy as the cursor moves over the grid.

2D Plot Options

• Frequency Integration Plot - Turn on to show an energy vs. frequency plot for the selected spectrum.
• Direction Integration Plot - Turn on to show a direction vs. energy plot for the selected spectrum.
