The format of the source information can be specified as
· Constant in time
· Varying in time
For the case with source information varying in time you have to prepare a data file containing the source information (discharge and/or velocity components) before you set up the hydrodynamic simulation. The data file must be a time series data 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. A linear interpolation will be applied if the time steps differ.
