The Run Rehearsal module allows the user to run simulations of an elections event.
Starting a Rehearsal Simulation
To run a simulation, first choose a rehearsal scenario from the Rehearsal Scenario drop-down list. If non are available, please create one as outlined in the Rehearsal Setup document.
Be aware that running a rehearsal simulation will overwrite the polls and votes for the contests of the elections event in the database. It won’t change the elected and acclaimed flags though as these flags are managed manually in Flow.
Before starting the simulation run, check the Step Duration value and modify it as desired. This duration value is only kept for this run. If the duration change is wanted for all future runs of the selected scenario, press on the Save Duration button 
.
Note that the grid will show the rehearsal steps for step 0 which will reset all the votes and polls to 0 when a simulation is started. You can change which step the simulation run starts on by changing the value in the Select Step control or pressing on the Next Step button to advance the steps shown in the grid.
Start the simulation by clicking on the Start Simulation button . The will change the button label to be Stop Simulation and also enable the Auto Next Step button .
This will write the values of step 0 (or whatever the start step you selected prior to starting the simulation) into the database.
You can start the Auto Next Step timer if you wish by clicking on the Auto Next Step button . This will start the timer and will show the count down time on the left of the button. Once the timer reaches 0:00, the step value will be advanced to the next step and the timer restarted.
To stop the timer, press the Auto Next Step button again. You can always advance the step by pressing on the Next Step button at any time during the simulation run. If the Auto Next Step timer is running, this will reset the timer after the Next Step button is pressed.
