The CGWAVE model requires several user-specified parameters to control the analysis. The Model Control command from the CGWAVE Menu opens the Model Control dialog. This dialog contains parameters that control the execution of CGWAVE. The parameter description for each field is displayed in SMS using the interactive help messages.
Controls include:
- Title
- Incident Wave Conditions
- Open Boundary – The Open Boundary section allows the user to specify the open boundary type. This should match the type selected when generating the domain in the Map Module. If the mesh has been generated using other methods, the domain shape must match the Open Boundary type.
- 1-D Options – The 1-D section allows the user to specify the number of nodes and the nodal spacing for the one-dimensional data that is used to distribute incident wave data to the open boundary. The file format is described in the CGWAVE user manual. The Compute 1-d Length button calculates the 1-d Spacing variable such that the specified number of nodes will extend to the limits of the bathymetry data. This bathymetry data is defined by a scattered dataset. Therefore, a scatter dataset must exist to in order for this button to be active. If no scatter data exists, the user must generate an appropriate file containing the one-dimensional depth values.
- Solver – CGWAVE support two separate numerical solvers for robustness. Users select which solver to use via the Solver radio group. The Standard solver should be utilized first. If CGWAVE fails to converge, the Modified method can be utilized.
- Iteration Control
- General Parameters
