I was able to simulate a large fire in Prometheus, but the simulation was very slow. What optimization techniques are available to speed up the simulation?
You can control the number of time steps and hence the number of vertices that are added by specifying the distance resolution in Advanced Scenario Parameters. Increasing the distance resolution will decrease the computation time but will compromise the ability of the model to capture all of the detail in the fuel type grid. You can also change the perimeter resolution in Advanced Scenario Parameters. This is the maximum distance allowed between two vertices along the fire perimeter. Increasing the perimeter resolution results in fewer vertices being added along the fire perimeter. • I simulated an actual fire, which I know did not burn during the night-time period. Is this feature available within Prometheus? Yes, you can control the active burning period anytime throughout the day by either setting the burning period or by setting thresholds for temperature and relative humidity. This option essentially turns off fire growth simulations outside the specified burning period. Night tim
