QUIC-Fire: A Fast, 3-D Simulation Tool for Prescribed Fire Planning

Photo of Orthogonal view of QUIC-Fire (left) and FIRETEC (right) simulation of Eglin Air Force Base prescribed burn at 120 and 300 seconds (top and bottom). Five staggered ignition lines were ignited (from right to left) at rates typical of all-terrain vehicle ignitions at Eglin AFB. Green iso-surfaces are vegetation density, oranges are mass loss rate, and white shades indicate locations of rising plumes.

QUIC-Fire is intended to serve as a core component of a prescribed fire planning tool that will assist land managers in understanding how ignition patterns connect to fire effects and smoke impacts.

Summary

Coupled fire-atmospheric modeling tools are increasingly used to understand the complex and dynamic behavior of wildland fires. But many of these tools require high-performance computing resources. QUIC-Fire is a new fire modeling tool designed to rapidly solve complex fire behavior problems. Unlike other modeling tools, QUIC-Fire can run on a basic laptop. QUIC-Fire can also represent fire atmospheric feedbacks, including those that govern prescribed fire behavior, at relevant scales.  QUIC-Fire was developed so that a broader set of users could explore fire prescriptions and how these prescriptions link to achieving a fire's objectives. QUIC-Fire simulates how fuel structure influences local winds and fire behavior in a similar manner as the state of the art computational fluid dynamics wildfire model, FIRETEC, developed at Los Alamos National Laboratory. QUIC-Fire uses 3D fuels inputs similar to this model. Results comparing fire behavior metrics between QUIC-Fire and FIRETEC show strong agreement. QUIC-Fire's ability to simulate the response to both ignition patterns and a temporally and spatially variable fire environment without the computational expense of fluid dynamics solutions was a critical design feature.
