If you have previously created a ResSim Simulation, you may want to make revisions to the Lookback date and time or End date and time (the Start date and time cannot be changed), or you may want to revise data in an Alternative (operation rules, reservoir operation zones, etc.). To accomplish this, you will open an existing Simulation.
The time period details of your selected Simulation will now appear in the Simulation Tree ("Figure: Simulation Tree"), and the map display will now update to show the model schematic for the Active Alternative (see "Setting the Active Component" for information about setting the alternative to active).

Editing a Simulation
Once you have created a Simulation, you can use the Simulation Period dialog ("Figure: Simulation Period") to edit the Lookback Date and Time, the End Date and Time, Time Step, and selected Alternatives. You cannot change the Start Date or Time.
You can access the Simulation Period dialog two ways:
Select Edit from the Simulation menu.
Right-click on the Simulation folder at the top of the simulation tree in the Simulation Control Panel, then select Edit from the context menu.
When editing a simulation, it may be necessary to recopy the time series data to the simulation.dss file used by ResSim for its computations. There are two methods available for doing this:
From the Simulation Period dialog, check the Run New Extract box and click OK.
In the Menu Bar, click Simulationī Rerun Extract.
