Directional Spread Models

Cosine blending produces wider fires while the elliptical model (Anderson, 1983) creates more realistic elongated shapes.

Wind Direction Rose

Eight wind directions with elliptical blending — the fire elongates in the wind direction.

Calm Wind

Near-zero wind produces nearly circular spread, driven primarily by the base rate of spread.

Burnout Ring

With burnout enabled, consumed fuel stops contributing to spread. The burnout-aware colormap shows actively burning cells (yellow/red) and consumed cells (black).

Slope Effect

Fire spreads faster uphill due to radiative pre-heating of fuels above the flame.

Dynamic Moisture

DynamicMoisture models fire-induced fuel drying — radiative heat dries nearby fuel, creating a positive feedback loop that accelerates spread.

Arrival Time Isochrones

The t_ignite field records when each cell ignited. White contour lines show fire front positions at equal time intervals.

Multiple Ignition Points

Three fires ignited at staggered times merge into a single perimeter. Arrival time coloring reveals the merge pattern.

Fuel Type Comparison

Different fuel models produce dramatically different spread rates and fire shapes under identical conditions.
