FDS is free software developed by the National Institute of Standards and Technology (NIST) of the United States Department of Commerce, in cooperation with VTT Technical Research Centre of Finland.
To date, about half of the applications of the model have been for design of smoke handling systems and sprinkler/detector activation studies.
The Wildland-Urban Fire Dynamics Simulator (WFDS) is an extension developed by the US Forest Service that is integrated into FDS and allows it to be used for wildfire modeling.
Smokeview (SMV) is a companion program that reads FDS output files and produces animations on the computer screen.
However, there are various third-party programs that have been developed to generate the text file containing the input parameters needed by FDS.
