NIST Fire Dynamics Simulator (FDS) and Smokeview


--------------------------------------------------------------------------------

Overview
FDS is a computational fluid dynamics (CFD) model of fire-driven fluid flow. The software solves numerically a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow with an emphasis on smoke and heat transport from fires. Smokeview is a visualization program that is used to display the results of an FDS simulation.

Obtaining FDS and Smokeview Version 4
Version 4.0.5 of FDS and Smokeview has been released (02/14/2005).
A setup program for Windows installing FDS, Smokeview, documentation and example files is available for download

Individual FDS and Smokeview executables may also be downloaded.

What's New in Smokeview
3D Smoke A method for visualizing smoke realistically has been implemented by using soot density to compute the transparency of a series of slice planes.
Tours Arbitrary paths or tours through a Smokeview scene may be created. One may then view the scenario from the vantage point of an observer moving along one of these paths. A Tour dialog box may be used to edit existing tours or create new ones.
Data Chopping Data from slice, particle and plot3d files may now be chopped or truncated. See additions to the Set Bounds dialog box to specify data bounds below and/or above which data will not be drawn.
What's New in FDS
Smoke detector activation FDS now contains a smoke detector activation model developed by Combustion Science and Engineering under a grant from NIST.
Parallel Processing It is possible to run an FDS calculation on more than one computer using the Message Passing Interface (MPI).
Multiple Meshes Improvements have been made to the multiple mesh capability allowing more flexiblity in designing simulations.
Layer Height A simple calculation of the layer (or interface) height has been added to FDS to enable users to compare FDS and zone model calculations or to present FDS results in a simplified manner.
Updates
An FDS/Smokeview self-installer is available. FDS and Smokeview have been updated to versions 4.0.5.
A new email list, fdstesters@nist.gov, is available for those interested in helping to test FDS and Smokeview.
Documentation now available for the DXF2FDS converter
