At any time during the running simulation, the Simulate > Resume/Suspend command or toolbar button can be toggled to suspend the simulation. The following dialog box will appear to let you know your suspend request was received.
The "Please Wait..." dialog box displays the approximate time until FARSITE gets to a good stopping point as some FARSITE processes cannot be interrupted. You can then confirm the suspend request by clicking the OK button or cancel the request with the Cancel Request button. If you do nothing FARSITE continues with the suspend request as if you clicked the OK button.
The operating status of the simulation will be displayed on the message bar at the bottom of the output screen (SIMULATION RUNNING or SIMULATION SUSPENDED). Once the simulation is underway suspending the simulation is recommended before performing modifications to the landscape or to the output features of FARSITE. Although it is possible to make selections and changes without suspending an active simulation, delays with screen output and message response can make feedback to the user difficult. Toggling the Simulate > Resume/Suspend command or toolbar button again will resume the simulation.
