NIST Improves Performance, Capabilities of Its Computer Fire Modeling Tools

Source: Forensic Mag

National Institute of Standards and Technology (NIST) scientists and engineers recently enhanced the capabilities of NIST’s computer fire modeling software, a powerful suite of tools used worldwide in research, arson investigations, firefighter training, and development of fire-protection designs and standards.
The just-released sixth version of the NIST Fire Dynamics Simulator (FDS) features new algorithms and other problem-solving routines, more accurate methods for predicting smoke concentrations and soot deposition, a new turbulence model, and other significant improvements. NIST also added features to its Smokeview program for visualizing fire behavior and phenomena predicted by FDS.
Together, the fire modeling tools help to unravel the complex physics and chemistry of fire. Since they were first issued for public use in 2000, FDS and Smokeview have proved to be one of the most important advances in the field of fire protection research and engineering in the last decade.
FDS “has become the tool of choice by both the fire research and fire engineering communities,” according to the International Forum of Fire Research Directors, an organization that promotes international cooperation in fire safety research. As a result, the forum says, “many new insights have emerged, further extending our understanding of the behavior of fire phenomena.”
