The Consolidated Model of Fire and Smoke Transport, CFAST, is a computer program that fire investigators, safety officials, engineers, architects and builders can use to simulate the impact of past or potential fires and smoke in a specific building environment. CFAST is a two-zone fire model used to calculate the evolving distribution of smoke, fire gases and temperature throughout compartments of a building during a fire.
The latest version of the software is designed to work with Windows and has been tested with Windows 7, WIndows 10, Linux, and OSX operating systems. The CFAST package includes NIST's Smokeview program, which visualizes with colored, three-dimensional animations the results of the CFAST simulation of a specific fire's temperatures, various gas concentrations and growth and movement of smoke layers across multi-room structures.
More information, including manuals, downloads, and support is available on the CFAST Website.
