BOUSS2D Runup / Overtopping Model Control dialog

The BOUSS2D Runup / Overtopping Model Control dialog is accessed by right-clicking on the Runup/Overtopping simulation and selecting the Model Control command. The dialog allows setting the following parameters:

• Project Title – Enter the title of the project in this field. The title is used for the folder name where the output files will be stored.
• Input Datasets – These inputs specify spatially varied input parameters for the model. In addition to the bathymetry, BOUSS-2D can utilize spatially varied damping, porosity and currents. In this section define whether these inputs are used (“None” is selected if not), and if so, how they are defined.
  • Damping – specified using boundary conditions on cell strings or selected from the scalar functions.
  • Porosity – specified using boundary conditions on cell strings or selected from the scalar functions.
  • Current – selected from the available vector functions.
• Time Control – The interface displays the recommended values for Duration and Time step in parentheses.
  • Duration – enter the model run duration.
  • Time Step – enter the number of time steps for the model run duration.
• Grid Information – This section displays the attributes of the active grid.
  • Cell Size – specifies the size of cells the model run will use.
• Porosity Friction Factors
  • Turbulent – value ranges from 0.0 to 3.6 with a default value of 2.4.
  • Laminar – value ranges from 0 to 1500 with a default value of 800.
  • Store Size – represents the characteristic stone size (d50) in meters of the breakwater armor layer and must be greater than zero.
  • Added Mass Coeff. –
• Parameters
  • Roughness Type – sets the Chezy coefficient type. Currently, only "Constant Chezy coefficent" is allowed. The Chezy coefficient ranges from 0.0 to 1000.0 (default = 50).
  • Smagorinsky Number – must be between 0.0 and 2.0 (default=0.2).
  • Nonlinear Option – can be set to either "Strong" or "Weak".
• Output Options

• Overide Default File Prefix – allows specifying a file name for these solution files. The default file prefix is the filename of the *.par file.

• File Prefix – becomes active once the Overide Default File Prefix is toggled on. A new prefix may be entered when active.

• Time Independent

• Output Significant Wave Height
• Output Mean Currents
• Output Mean Water Level
• Output Max Inundation Water Level
• Output Format – gives options to output in an "XMDF" file, a "BOUSS-2D Native" file, or "Both".

• Animation Output

• Output WSE – tells the model to output time varying datasets.
• Output Velocity – tells the model to output time varying datasets.
  • Number of Frames
  • Required Memory
• Override Defaults – Enables the Begin Output, End Output, and Step controls.
  • Begin Output – must be greater than 0.0 and less than the run duration.
  • End Output– must be greater than 0.0 and less than the run duration.
  • Step – determines how often the model will save time-varying output.
