roject Scorch was a technology preview that helped users who need to perform fire simulations within a structure. Project Scorch used the NIST Fire Dynamics Simulator to understand fire behavior within a building, such as smoke development and propagation, sprinkler behavior, and more. Project Scorch was a more efficient and easier to use front end for FDS from simulation set up and results exploration. The technology preview has ended. Thanks to everyone who participated. Users who wish to continue to work with the technology can work with NIST Fire Dynamics Simulator directly.
