Description

Toolbox

To perform a number of operations according to the Toolbox selected from the Toolbox tab in the Top Menu.  For all the supported models this is the quick mode of the model maker and the possibility to combine several sources of bathymetry.

Description

To add a description to the communication file (MDW file eg.) to describe the purpose of the present model.

Hydrodynamics

Delft3D-WAVE can be use uncoupled (stand-alone) or coupled (offline and online). When choosing the coupled option the user needs to specify the MDF-file of the specific Delft3D-FLOW model. Another possibility is the online with Dashboard Flow. This option will automatically result between a coupling between FLOW and WAVE.

Grids@

Time Frame

Defines the relation between the time axis of the real world (absolute time) and that of the simulation (relative time). “Reference Date” defines the arbitrary time t = 0 for all the time series computed by the simulation. “Start Time” and “Stop Time” defines start time and end time of the simulation. “Time Step” defines the Time step (in minutes) used in the computation. “Time Zone” defines the time difference between local time and GMT time and it is used to determine the phases in the local time of the tidal components when tide generating  forces are included in the simulation.computational mode (stationary or non-stationary) and the time points for the WAVE computation.

Boundaries

To define the boundaries, their location, type and other parameters describing them. It is possible to vary conditions in space and orientation. The wave spectrum can be created based on parametric relation or via the usage of a file.

ObstaclesDefines obstacles in the Delft3D-WAVE simulation. There are two possiblities: sheet & dam. The user can simply click in the Delft Dashboard in order to specifiy specify the area where an obstacle is needed. Double click to finlalise finalize the line.

Physical Parameters

To select or specify a number of parameters related to the physical conditions of the model area. The data Group Physical parameters contains the following sub-data groups in the Working Space: Constants, RoughnessWind, Viscosity, Sediments, Morphology, Heat Flow, Wind. The  tabs for Constants, Roughness and Viscosity are always visible. The other tabs are only visible if the associated processes are switched onProcesses, Various. All the tabs are always visible

  • Constants: to define values for: “Gravity”, “Water Density”, North axis, minimum depth, wave set-up, cibvections convection (nautical or cartesianCartesian) and options for wave forces.
  • Wind: to add a wind field or apply a uniform wind speed and direction. A wind field can is be saved to as a “* .wnd” wnd file.
  • Processes: to define a whole number of processes. SWAN can run in several modes, indicating the level of parameterization. Default is the 3rd generation which supports depth-induced wave breaking, LTA, bottom friction and diffraction. More information about these processes can be found in the Delf3D-WAVE manual.
  • Various: several processes can be activated like wind growth, quadruplets and white capping, refraction and a frequency shift.

Numerical Parameters

To specify parameters related to drying and flooding and some other advanced options for numerical approximationsthe spectral space and the accuracy criteria.

Output

To select or specify output there a number of possibilities. The data Group Output contains the following sub-data groups in the Working Space: General, Grids, Locations, Curves and Debug. All the tabs are always visible. 

  • General: x
  • Grids: x
  • Locations: x
  • Curves: not yet implemented in Dashboard
  • Debug: x

  specify “Start Time”, “Stop Time”, “Time Step” at which output data will be stored in the Map output File. In case of simulation run with coupling, “Start Time”, “Stop Time” and “Time Step” at which data will be saved in the communication file can be specified. Moreover, the “History Time Step”, defining the time step at which information is stored for the observation points, can be specified. “Online visualization” is used to inspect results during the computation. “Online coupling” is available when you store results to the communication file.
