Coupled fire-atmospheric modeling tools are increasingly used to understand the complex and dynamic behavior of wildland fires. Multiple research tools linking combustion to fluid flow use Navier-Stokes numerical solutions coupled to a thermodynamic model to understand fire-atmospheric feedbacks, but these computational fluid dynamics approaches require high-performance computing resources. We present a new simulation tool called QUIC-Fire to rapidly solve these feedbacks by coupling the mature 3-D rapid wind solver QUIC-URB to a physics-based cellular automata fire spread model Fire-CA. QUIC-Fire uses 3-D fuels inputs similar to the CFD model FIRETEC, allowing this tool to simulate effects of fuel structure on local winds and fire behavior. Results comparing fire behavior metrics to the computational fluid dynamic model FIRETEC show strong agreement. QUIC-Fire is the first tool intended to provide an opportunity for prescribed fire planners to compare, evaluate and design burn plans, including complex ignition patterns and coupled fire atmospheric feedbacks.

越来越多地使用耦合的火-气建模工具来了解野火的复杂和动态行为。多种将燃烧与流体流动联系起来的研究工具使用Navier-Stokes数值解和热力学模型来理解火气的反馈，但是这些计算流体动力学方法需要高性能的计算资源。我们提出了一种称为QUIC-Fire的新仿真工具，通过将成熟的3-D快速风求解器QUIC-URB耦合到基于物理的细胞自动机火势蔓延模型Fire-CA来快速解决这些反馈。QUIC-Fire使用类似于CFD模型FIRETEC的3-D燃料输入，从而使该工具能够模拟燃料结构对局部风和火势的影响。将火灾行为指标与计算流体动力学模型FIRETEC进行比较的结果显示出很强的一致性。QUIC-Fire是第一个旨在为指定的消防计划人员提供机会来比较，评估和设计燃烧计划的工具，其中包括复杂的点火模式和耦合的火灾大气反馈。
