SMS:BOUSS-2D Simulations

Simulations are available in BOUSS-2D starting in SMS 11.2. A simulation should contain a BOUSS-2D grid, a wave maker coverage, and optional damping and porosity coverages. Right-clicking on the simulation will display the options and dialogs.

To create a new Simulation:

1. Right-click on empty space in the project explorer and select New Simulation→BOUSS-2D
2. Drag and drop bouss2d grid, wave maker/damping/porosity coverages under the newly created Simulation tree item.

A New tree item will appear

Menu Commands

Right-clicking on the simulation tree item will display a list of menu commands and dialogs that are available. These items are:

• Generating Arcs along land boundary – open a dialog that will create arcs in a damping or porosity coverage from an existing grid or scatterset.
• Generating Arcs along open boundary – open a dialog that will create arcs in a damping or porosity coverage from an existing grid or scatterset.
• Calculators
• Spectral Energy
• SMS:BOUSS-2D ProbesProbe Manager
• Model Control

Output Options

The user can instruct BOUSS-2D to create a variety of output files. These may include spatially varied data consisting of a value for each cell in the grid, transient data defining time series at a location, or a combination of these two options (multiple time steps of data that includes a value at each cell). The output options, along with the keyword included in the parameter file to enable these options are shown below.

• Steady-state/single value spatially varied datasets

• Significant wave height (":HS_FILE")
• Mean currents (":MEAN_UV_FILE")
• Mean wave direction (":THETA_FILE")

• Transient spatially varied datasets. Each output includes data from a specified start time, to a specified end time at a specified time step.

• Water surface elevations (":SAVE_ETA_ANIMATION")
• Transient currents (":SAVE_UV_ANIMATION")

• Time series output at specified cells (probes). BOUSS-2D saves each type of data (for multiple locations) in a single "*.ts1" file.

• Water surface elevations (":TS_ETA_FILE")
• Currents (":TS_U_FILE", ":TS_V_FILE") – This saves the current at a specified elevation up from the bed. Multiple elevations can be monitored.
• Pressure (":TS_PRESSURE_FILE") – This saves the pressure at a specified elevation up from the bed. Multiple elevations can be monitored.
• Flow rate (":TS_Q_FILE" – This saves the flow crossing a location and can be used for overtopping.

The spatially varied data may be output in to either BOUSS-2D native files or a eXtensible Data Format File (XMDF). If BOUSS-2D format is specified, the model creates "*.grd" files for each of the single value spatially varied outputs and binary data files for the transient data. The ":SOLUTION_FILE_OPTION" in the par file instructs the model to save the data in BOUSS-2D format (if set to 0), XMDF format (if set to 1) or both formats (if set to 2). When the XMDF option is specified, the ":XMDF_SOLUTION_FILE" record must also be in the parameters file along with the name of the XMDF file to store the datasets in.

The output options are located in the model control.

• Model Check – The model check will warn you of potential errors that you should consider fixing before running the model.
• Exporting – When the BOUSS-2D files are exported a new directory under the project called “BOUSS-2D” is created. In this directory the grids will be written to. Also a new directory under the “BOUSS-2D” will be created and it will be the name of your simulation. In this directory you will find the *.par file(link to Parameter file)
