The group is recognized for developing the Fire Dynamics Simulator (FDS) fire modeling software, an outstanding technical achievement in the practical application of fire science, and an innovative engineering tool for cost-effective fire-safe design of structures. FDS bridges the gap between basic research and practical application, while maintaining the highest standards of scientific rigor. FDS has had a significant impact on improving fire safety and reducing annual fire losses. The Fire Dynamics Simulator has revolutionized how performance-based fire safety design is implemented in the U.S.
