What is "flacs"

FLACS (FLame ACceleration Simulator) is a commercial Computational Fluid Dynamics (CFD) software used extensively for explosion modeling and atmospheric dispersion modeling within the field of industrial safety and risk assessment. Main application areas of FLACS are in petrochemical, process manufacturing, food processing, wood processing, metallurgical, and nuclear safety industries.

FLACS has dedicated modules to simulate gas explosion, dust explosion and explosions involving chemical explosives like TNT. FLACS is also extensively used to simulate flammable and toxic gas dispersion. It was applied in the investigation of many high profile accidents such as Buncefield fire, Piper Alpha, TWA Flight 800, and the Petrobras 36 platform.
