Button | Description |
---|---|
Toolbox | To perform a number of operations according to the Toolbox selected from the Toolbox tab in the Top Menu. |
Description | To add a description to the MDF file i.e. to describe the purpose of the present model. |
Domain | The data Group Domain contains the following sub-data groups in the Working Space: Grid, Bathymetry, Dry Points, Thin Dams, Structures.
|
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. |
Processes | The data Group Processes contains the following sub-data groups in the Working Space: Constituents, Physical, Anthropogenic.
|
Initial Conditions | To specify the initial values the computation will start with. Initial conditions are required for all processes specified under the Tab Processes. A number of options can be selected: “Uniform Values” to impose a constant value, “Initial Condition File”, “Restart File”, and “Map File” to impose a value from external file. |
Boundaries | To define the open boundaries, their location, type and other parameters describing them. Boundary conditions are stored in the “.bnd” file. The following “Type” of boundary conditions are available: “Water level”, “velocity”, “Neumann” (water level gradient), “discharge” or flux (total or per grid cell), “Riemann” (or weakly reflective boundary). Each boundary is identified by its “Name”, start and end coordinates (“M1”, “N1”; “M2”, “N2”), reflection coefficient (“Alpha”), type of forcing (“Astronomic”, “Harmonic”, “Time-series”, “Q-H relation”). Moreover, the vertical profile for hydrodynamics can be selected between one of them: “Uniform”, “Logarithmic”, “Per Layer”. This last choice does not apply for “Water Level” or “Neumann: controlled boundary sections, neither for a depth-averaged simulation. |
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, Roughness, 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 on.
|
Numerical Parameters | To specify parameters related to drying and flooding and some other advanced options for numerical approximations. |
Discharges | To add localized discharges (e.g. rivers, intake stations, waste water outfalls). Location and discharge rates are respectively saved to a “.src” and “.dis” file. |
Monitoring | To monitor the simulation during time on a higher temporal resolution than the rest of the grid points, by specifying a number of Stations, Cross sections or Drogues. Drogues can be released anywhere in the grid and the patch of the particle moving with the flow can be followed. |
Output | To 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. |
