SMS:CMS-Wave Model Control

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:

Settings

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

• Allow wetting and drying
• Forward reflection
• Backward reflection
• Bed friction
• Diffraction intensity
• Wave breaking formula
• Currents
• Muddy bed

Wave Source

The wave source options include:

• Spectra – wave state is specified as a wave spectrum on the boundary and the model propagates the spectra over the domain
• Wind – waves are generated from wind energy only
• Spectra and wind – a combination of the spectra and wind types are used
• Simplified formulation – boundaries are specified in the same manner as "Spectra and wind", but the model uses a simplified formulation internally. This can be used for faster run times, however the results will be less accurate.
• Currents – specify a dataset and timestep
• Surge – specify a dataset or set to be spatially constant
• Use dates – associate dates/times with the model
• Spectra –
  • None – spectral data is not used in the simulation
  • Single – the grid's spectral data is used
  • Spatially varied – spectral input is used from a spectral coverage
  • From parent grid – spectral input is used from a parent grid
• Wind –
  • None – wind data is not used in the simulation
  • Constant – wind data is constant throughout the simulation
  • Varied – a vector dataset is used to define the wind data
• Simplified formulation – boundaries are specified in the same manner, but the model uses a simplified formulation internally. This can be used for faster run times, however the results will be less accurate.

Output

The output section is used to specify optional output from the model including:

• Radiation stresses
• Sea/swell
• Additional output: sea/swell, sea/swell/total, total
