This paper discusses the current capabilities of zone fire modeling. CFAST is used as the example, but as discussed at the end, the fundamental concepts are applicable to a wide range of models, available around the world. While there are aspects of the current model such as horizontal smoke movement that are features of CFAST, the basic conservation equations, methods of solution and idfficulties are common to the whole spectrum of this class of building system models.
