Public release of the NIST fire dynamics simulator 2.0

Official release versions of NISTs computer programs for modeling and visualizing fire and smoke flow, Fire Dynamics Simulator 2.0 and Smokeview 2.0, are now available for download at http://fire.nist.gov/fds/. The NIST Fire Dynamics Simulator predicts smoke and/or air flow movement caused by fire, wind, ventilation systems, etc. Smokeview visualizes the predictions generated by the Fire Dyanamics Simulator.

The Fire Dynamics Simulator is a computational fluid dynamics model which solves a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flows of smoke and hot gases generated in a fire. Version 2.0 of the Fire Dynamics Simulator includes improved combustion and radiation algorithms. Details of the numerical methods may be found in the Fire Dynamics Simulator Technical Reference Guide (NISTIR 6783). Smokeview visualizes the Fire Dynamics Simulator computed data by animating time dependent particle flow, two-dimensional slice contours and surface boundary contours. Details about Smokeview may be found in the Smokeview User's Guide (NISTIR 6761). Version 2.0 of Smokeview includes new visualization techniques such as animated isosurfaces and animated flow vectors. Instructions on how to use the Fire Dynamics Simulator and Smokeview can be found in the Fire Dynamics Simulator Users Guide (NISTIR 6784).
