SMS:CMS-Wave Model Control

CMS-Wave Model Control dialog

The Model Control… command in the CMS-Wave Menu opens the CMS-Wave Model Control dialog. This dialog is divided into sections for different types of parameters which are used by the model as it runs. These include:

Input Forcing

• Currents – A vector dataset can be used to define the currents for the simulation
• Water Level – A constant value or a scalar dataset can be used to define the water level for the simulation. If “constant” is selected, the constant value will be defined in the CMS-Wave Case Definition dialog for each case.
• Spectra
  • Plane Type – this option is only used if the Spatially Varied source option is selected.
    • "Half plane" – appropriate for nearshore coastal applications allowing wave input and generation on two boundaries resulting in a faster run-time.
    • "Full plane" – used with enclosed or semi-enclosed bays, estuaries, and lakes where there is no clear “offshore” direction and seas and swells may oppose each other. Allows wave input and geration on all four boundaries.
    • "Full plane with input reverse spectra" – this option allows spectral input to be used on two opposite boundaries.
  • Interpolation Type – sets the method for STWAVE to use when interpolating between spectra.
    • "Average spectra"
    • "IDW interpolation" – Inverse Distance Weighting
  • Spectral Grid
  • Create Nesting Points – if the From parent grid source option is selected and a parent grid has been specified, clicking on this button will allow specifying which points should be used from the parent grid for creating the nesting file.
• Wind – a constant value or a vector dataset can be used to define the wind for the simulation. If constant is selected, the wind direction and magnitude will be specified in the CMS-Wave Case Definition dialog for each case.
• Define Cases

Settings

The settings section is used to specify model input options including:

• Bed friction
• Matrix Solver
  • Gauss-Seidel
  • ADI
• Allow wetting and drying
• Infragravity wave effect
• Diffraction intensity
• Forward reflection – A constant value for the entire simulation or spatially varying data using a scalar dataset can be used to define the forward reflection for the model.
• Backward reflection – A constant value for the entire simulation or spatially varying data using a scalar dataset can be used to define the backward reflection for the model.
• Muddy bed – Spatially varying data using a scalar dataset can be used to define the muddy bed (values??) for the model.
• Non-linear wave effect
• Run up
• Quick mode

Output

This section is used to specify option output from the model. The output includes:

• Radiation stresses
• Sea/Swell
• Wave Breaking

Input Datasets

Here specify the format for SMS to write out the input datasets. They can be written in either ASCII or XMDF format.
