Data

If specified values (Dirichlet boundary condition)  is selected the format of the temperature and/or salinity at the boundary can be specified as

·         Constant (in time and along boundary)

·         Varying in time and constant along boundary

·         Varying in time and along boundary

For the case with boundary data varying in time but constant along the boundary you have to prepare a data file containing the boundary values (temperature or salinity) before you set up the hydrodynamic simulation. The data file must be a time series file (dfs0). The data must cover the complete simulation period. The time step of the input data file does not, however, have to be the same as the time step of the hydrodynamic simulation. You can choose between different types of interpolation (see Interpolation type).

For the case with boundary data varying both in time and along the boundary you have to prepare a data file containing the boundary values (temperature or salinity) before you set up the hydrodynamic simulation. In case of 2D sim­ulation the data file must be a profile file (dfs1). In case of 3D simulation the data file must be a dfs2 file or a 2D dfsu file containing information from a vertical plane. The data must cover the complete simulation period. The time step of the input data file does not, however, have to be the same as the time step of the hydrodynamic simulation. You can choose between differ­ent types of time interpolation (see Interpolation type).
