Graphical Interface
The CMS-Wave graphical interface includes tools to assist with creating, editing, and debugging a CMS-Wave model. The CMS-Wave interface exists in the Cartesian Grid Module.
Map Coverages
SMS contains specific coverages for use with CMS-Wave. This coverages include:
- Observation cells – Points created on this coverage will define observation cells for the simulation.
- Nesting points – Points created on this coverage will define nesting points for the simulation.
- Structures – Contains options for defining structure modifications.
Model Control
The CMS-Wave Model Control dialog is used to setup the options that apply to the simulation as a whole. These options include time controls, run types, output options, global parameters, print options and other global settings.
Running the Model
The CMS-Wave files are written automatically with the SMS project file or can be saved separately using the File | Save CMS-Wave or Save As menu commands. See CMS-Wave Files for more information on the files used for the CMS-Wave run.
CMS-Wave can be launched from SMS using the CMS-Wave | Run CMS-Wave menu command. A check of some of the common problems, called the Model Checker, is done each time the model is launched, or by selecting the CMS-Wave | Model Check menu command.
Visualizing Results
Select the spectral grid as the grid to use in the Spectral Energy dialog. This will open the spectral grid for viewing in the Spectral Energy dialog. Make sure to set the original grid back before leaving the dialog to ensure the model does not change.

- "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.

- "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.

- 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.

Menu
The simulation right-click menu includes the general simulation commands Delete, Duplicate, and Rename along with the following model specific commands:
- Model Control
- Brings up the CMS-Wave Model Control dialog. The dialog allows viewing and editing the current parameters that affect how CMS-Wave runs and what options are to be included in the current simulation.
- Model Check
- Check for common problems. If problems are found, the Model Checker dialog will open.
- Save Simulation
- Tells SMS that it is time to write out the files that CMS-Wave needs to run. Note that the project must be saved before the files may be exported. The user will not see anything happen, but SMS uses the input information from the model control, the boundary conditions, and quadtree data to create the files in preparation for CMS-Flow to work.
- Run Simulation
- When the model is ready and has been exported, it may be launched. Launching CMS-Wave initiates the model run for the simulation. Upon successful completion of the launch, the analysis is complete and results are ready to be read and displayed by SMS.
- Save Project, Simulation, and Run
- This is a combination of the previous steps put together into one.
