Now that all modifications to the CMS-Flow grid alternatives have been finalized, the wave grid can be generated from the Flow grid. CMS-Wave grids are typically generated from scatter datasets, but can be a mirror image of the flow grid if the boundary condition (BC) locations are close enough to force both the tide and waves from the same BC area. In the near future, CMS will have the option to be run fully inline, where only one grid will contain all of the information needed to run both CMS-Wave and CMS-Flow.
The CMS-Wave IJ triad should be adjusted where the I-direction is pointing in the dominant wave direction, or more specifically from the open ocean. This means that it will be 180 deg off as compared to the CMS-Flow grid. Therefore, after the CMS-Flow grid is generated, the model domain should be set to include all major reaches of the bay, extending laterally a couple kilometers from the inlet and extending seaward well beyond the anticipated reach of the ebb jet. A good rule of thumb for setting the ocean boundary for inlet modeling is to place the boundary three or four times the length of the ebb jet (leaving provision for extreme discharges, such as during storm surge). The given bathymetry ends at approximately four times the length of the ebb jet at Shark River.

- Transforming the CMS-Flow grid to a CMS-Wave Grid
1. Open one of the generated grids rt-click the Grid in the SMS list, and click on Duplicate, select the copied grid (copy) to activate it, and go to Data, Switch Current Model (Figure 28),
2. Change the Model from CMS-Flow to CMS-Wave, click OK, and rename the grid by rt-clicking on the copy name and clicking Rename,

3. Set the jetty and groin cells to rubble-mound type structures by selecting the cells (Figure 27), and rt-click, Cell Attributes.., and select a Rubble-mound from the Structure Type, click OK.
4. File, Save As, Wave.sim (selecting the Save As Type as a .sim for simulation) in the folder with the CMS-Flow grid.
