CFAST是一种能够预测火灾下多室结构环境的区域模型。它计算在用户指定的火灾期间整个建筑物内烟雾和火灾气体的时间演变分布以及温度。本报告描述了构成模型的方程、这些方程的物理基础、模型使用的数据以及实现模型的计算机程序的操作细节。详细介绍了可以添加新现象的方法，以及模型的变量和结构。一组模型和一系列的真实规模的火灾实验之间的比较。在一般情况下，CFAST模型与本文研究的实验相比，毫不逊色。虽然模型和实验之间的差异很明显，但它们可以用模型和实验的局限性来解释。
CFAST is a zone model capable of predicting the environment in a multi-compartment structure subjected to a fire. It calculates the time evolving distribution of smoke and fire gases and the temperature throughout a building during a user-specified fire. This report describes the equations which constitute the model, the physical basis for these equations, data which are used by the model, and details of the operation of the computer program implementing the model. The means by which one can add new phenomena are detailed, as are the variables and structure of the model. A set of comparisons between the model and a range of real-scale fire experiments is presented. In general, the CFAST model compares favorably with the experiments examined in this paper. Although differences between the model and the experiments were clear, they can be explained by limitations of the model and of the experiments.
