In cooperation with the fire protection engineering community, a numerical fire model, Fire Dynamics Simulator (FDS), is being developed at NIST to study fire behavior and to evaluate the performance of fire protection systems in buildings. Version 1 of FDS was publicly released in February 2000, and Version 2 in December 2001. To date, about half of the applications of the model have been for design of smoke handling systems and sprinkler/detector activation studies. The other half consist of residential and industrial fire reconstructions. Throughout its early development, FDS had been aimed primarily at the first set of applications, but following the initial release it became clear that some improvements to the fundamental algorithms were needed to address the second set of applications. The two most obvious needs were for better combustion and radiation models to handle large, spreading fires in relatively small spaces like residences as opposed to industrial settings.
