Creation of a Short Term Simulation

The short-time simulation (simulation time step size < 1440 minutes) is used to calculate single events and is limited to 2880 time steps. The short-time simulation is based on the determined initial values of the long-term simulation. For this purpose, a new simulation has to be run. The integration of the initial values in the simulation is carried out by the assignment of a long-term computing variant in the Simulation Management.

Procedure

Short Term Simulation

Using the button Feature New a new calculation variant can be created. In the feature view, the following data can be completed and the calculation of the simulation can be started with

Description

The created simulation can be renamed via . In short time simulations, a variation of names is recommended for better mapping of Short Term Simulations.

Start the Simulation

The start of the simulation must be at 00:00:00 (example: 28.07.2002 00:00:00).

End the Simulation

The end of the simulation must be completed at 00:00:00 (example: 04.08.2002 00:00:00).

Time steps

To create a short time simulation, it is recommended to specify a time step size of 5 in minutes (even 10 or 15 minutes). However, a calculation version is carried out with a maximum length of 2,880 time steps.

Version Kalypso-NA (calculation core)

Here the latest version of the calculation core should be selected (for information on calculation engine: see Computing core Computing core).

Time Series Mapping

The initially loaded time series must be selected in the respective drop-down menu (Precipitation model, Temperature, Evaporation , Eater level or Discharge measurement, Inflow, open water Evaporation), and which was assigned to a Time Series Area Model using the time series mapping function.

Integration of initial values

To use initial values from a long-term simulation in a short time simulation run, the respective long term simulation must be selected in the Feature view Simulation Management section at the point of initial values of , from which the initial values should be drawn.
