Running an Incident Simulation

Before starting a simulation, choose your start time from the timeline tool. You may find it helpful to display IRWIN incidents on the map prior to starting an Incident Simulation. Then follow the steps below to run an Incident Simulation.

Steps:

1. Set Simulation Type to Incident

2. Use the select incident tool to open a list of current incidents

• The list of incidents can be searched, sorted, and filtered to find the incident you wish to run

• Double-click the incident to select it

3. Select Simulation Mode

• Fire Spread (NRTFB)

• Probabilistic (See Using Probabilistic Mode for info)

• Exposure (See Using Exposure Mode for info)

• Adjust

• Static

4. Enter/Confirm Duration for simulation to run (1-84 hours).

• Duration start and end dates/times will be displayed to the right.

5. Adjust Start Time

• Enter a date/time in the Start Time field or select a Start Time from the Timeline controls.

6. Choose Weather Data to use - Forecast, Constant, or Station values

• See Weather Data for Simulations for info about using Constant or Station values

• Most users should use the default forecast weather data

7. Enable Wind Ninja if desired

8. Adjust Surface Fuel Data if desired

• See Surface Fuel Data Conversion for Simulations for info about using the Surface Fuel Conversion Tool

• Most users should use the default data.

9. Select Fuel Scenario

10. Click Run Simulation

If you are not able to see an incident, try clearing your Areas of Interest filter in settings.
