In this dialog you must specify simulation period information:
· Time step range is the number of time steps the simulation should cover.
· The time step interval is the amount time is incremented between each time step (equal for all areas). In case of a hot-started simulation, the time step is taken from the hot file and cannot be changed.
· The simulation start date is the historical date and time corresponding to time step zero. In case of a hot-started simulation, the simulation start date is read from the hot file and cannot be changed.
· The warm-up period is a number of time steps over which the forcing functions are gradually increased from zero to 100% of their true value.
Before you leave this dialog, the system will calculate and show the maximum Courant Number (p. 95) in the model. The calculation assumes a constant mean water level of 0.0. You should consider reducing the time step if this Courant number exceeds (say) 8 to 10.
For your information, and as a possible check on parameter specifications, the simulation end date (and hour) is calculated and shown in the dialog.
