F - Flow of gases, vapor and particulates in a compartmentalized facility
A - Aerosol Generation and Transport Facility
T - Thermal Response of Rooms and Equipment 
E - Explosion Hazards From Flammable Gases and Entrained Particulates (Dust)

FATE is a practical modeling tool which captures the essential physics without resorting to CFD (Computational Fluid Dynamics) techniques. Thus FATE is amenable to modeling highly compartmentalized facilities without being computationally expensive. FATE provides significant technical advantages over other lumped-parameter codes...
