Fire simulation method, program, and storage medium

Abstract

Simplify fire simulations at the evaluation site. [Solution] In the fire simulation method, the evaluation target point P is set as the point of origin, and the fire spread diffusion time Td is estimated. Multiple assumed fire spread areas R1 to R4 are set centered on the evaluation target point P according to the fire spread diffusion time Td, and when a fire starts in each of the multiple assumed fire spread areas R1 to R4, the fire spread arrival time Tr, which is the time it takes for the fire to reach the evaluation target point P from each of the multiple assumed fire spread areas R1 to R4, is estimated based on the fire spread diffusion time Td.
