Central Registry Toolbox Code Version(s): V3.1.7 and 5.1.1
Code Owner: National Institute of Standards and Technology (NIST).

Description: 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 predict 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.

In May 2004, DOE performed an evaluation of CFAST against DOE's safety software quality assurance criteria. A gap analysis report was generated that identifies the strengths and weaknesses based upon ASME NQA-1 criteria. Upon completion of this evaluation, CFAST V3.1.7 and 5.1.1 were included in DOE's safety software Central Registry as a safety analysis toolbox codes.

Version 6.2.0 is currently being evaluated for inclusion in the Central Registry.
