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.
