The Spectral Energy dialog can be accessed when the spectral coverage is active. The dialog is opened by either double-clicking on a selected node/point or by right-clicking on a selected point and choosing the Point Attributes command. The spectrum represents energy densities at discrete values over a range of angles and a range of frequencies for a given wave condition.
Tools
Select Cell – Select a cell corner to view or edit the energy value.
Pan – Pan the spectral grid.
Zoom – Zoom in the window.
Rotate – Rotate in the window.
Frame – Frame, or zoom to the extents of the grid.
Contour Options – Bring up the contour options dialog for setting the spectral grid contour display options.
Grid Options
- Create Grid – Brings up the Spectral Grid Attributes dialog followed by 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 a location can be chosen 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.
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 a location can be chosen to save the spectra.
- Delete Grid or Delete Dataset – 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.
- Edit Time – Edit the time offset for the dataset.
View Options
- View – View and edit the spectral grid using a Cartesian or polar view.
Graphic Options
Information for points in the grid can be displayed in two ways:
- 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.
Reference Time
Clicking on the Update Reference Time... button will bring up the Time Settings dialog with the following options.
- Reference Time – Specify the reference time for all datasets assigned to the node
- Time Units – Specify the units for the time offsets assigned to the datasets
