Olivier,

here's one way to do it. In the BatchSwarm and/or the ObserverSwarm, you 
insert code like this:

// a. In method buildActions() insert a stop schedule like this (where 
'experimentDuration'
// is the step at which you want the simulation to stop):

      stopSchedule = new ScheduleImpl(this.getZone(), true); // autodrop

      stopSchedule.at$createActionTo$message
           (experimentDuration, this, new Selector
                (this.getClass(), "stopRunning", false) );


// b. Then you need a method like this that executes when the above action 
is triggered:

    public void stopRunning () {

        System.out.println
                ("BatchSwarm: Quitting at " + Globals.env.getCurrentTime() );

        // (Do other desired housekeeping chores here)

        Globals.env.getCurrentSwarmActivity().terminate();

    }

That should take care of it. (Translate as needed if you are running 
objective-C.)

Cheers,
