| The model CGWAVE (Demirbilek and Panchang 1998) is a two-dimensional wave transformation model that can be used to predict wave properties (wave heights, velocities, pressures, radiation stresses) in domains of complex shape and depth variations when an input wave condition (amplitude, direction, and period; or a spectral combination of these) is provided.

| ===Menus===
| |
| The following menu commands are available in the [[SMS:CGWAVE|CGWAVE]] Menu:
| |
| * [[SMS:CGWAVE Boundary Conditions Dialog|'''Assign BC''']]
| |
| <blockquote>
| |
| This command is used to assign boundary conditions along a selected [[SMS:CGWAVE Boundary Conditions Dialog|nodestring(s)]].
| |
| </blockquote>
| |
| *'''Material Properties'''
| |
| <blockquote>
| |
| Material properties can be assigned and defined.
| |
| </blockquote>
| |
| <blockquote>
| |
| *''Bottom friction'' – The bottom friction can be specified for the element(s) and material selected in this field.
| |
| * ''Floating dock'' – Represent an object anchored in place, but floating in or on the water and thereby obstructing wave fields. Elements will be treated as floating barriers when the simulation is saved.
| |
| </blockquote>
| |
| * '''Model Check'''
| |
| <blockquote>
| |
| Check for common problems. The ''model checker'' performs the generic mesh checking along with optionally checking to insure:
| |
| </blockquote>
| |
| <blockquote>
| |
| * that all boundaries mesh boundaries are assigned as land with a reflection coefficient or as open ocean.
| |
| * that all water depths are positive.
| |
| </blockquote>
| |
| * [[SMS:CGWAVE Model Control|'''Model Control''']]
| |
| <blockquote>
| |
| Brings up the ''Model Control'' dialog to specificy model parameters. </blockquote>
| |
| *'''Reset 1D Spacing '''
| |
| <blockquote> ... </blockquote>
| |
| *'''Run CGWAVE ''''
| |
| <blockquote>Brings up a dialog that allows the user to check what executable of CGWAVE should be run and then runs the model with the currently loaded simulation. As the model runs, a dialog monitors progress of the model and gives the user status messages. When the run is complete, the spatial solutions are read in for analysis and visualization. </blockquote>

| | |
| ====Obsolete Commands====
| |
| The following commands are no longer in current versions of SMS.
| |
| * [[SMS:Spectral Energy|'''Spectral Energy''']]
| |
| <blockquote>
| |
| Brings up the ''Spectral Energy'' dialog to define/view wave energy spectra. This command also allows the user to visualize wave spectra.
