Data

In case you choose to import a data file you have to prepare a data file containing the three components of the wave radiation stress divided by the density of water before you set up the hydrodynamic simulation. The file must be a 2D unstructured data file  (dfsu) or a 2D grid data file (dfs2). The area in the data file must cover the model area. If a dfsu-file is used piecewice con­stant interpolation is used to map the data. If a dfs2-file is used bilinear inter­polation is used to map the data. 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. A linear interpolation will be applied if the time steps differ.
