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.
