It is important to investigate cause and origin of fires to reduce damage and casualties. The difficulty of determining them has occurred because fires often destroy the key evidence. In this study, CFD-based Fire Dynamics Simulator (FDS) was used to reconstruct fire scene and presume origin of the Seomun market fire that occurred on November 30, 2016, in Daegu Metropolitan City. Comparing result of simulation with testimony of first witness and fire-fighters, it was estimated that the fire occurred outside of the market and sprinkler system worked. First-aid fire fighting was unsuccessful because of retardation of smoke detector activation. Fire-spreading into the building was delayed by the sprinkler system operation. And, it was found that tent covered on the stall accelerated fire spread.
