A VISUAL SIMULATION METHOD AND SYSTEM FOR HAZMAT DISPERSION FROMUSER DEFINED 3D BUILDING POSITION

摘要

The present invention relates to a method and a system for visualizing a simulation result into a dispersion flow of a toxic chemical. If a user designates, with a mouse, a specific site of a building, from which a toxic chemical is generated and discharged, shown on a screen of a monitor, the method uses a three-dimensional city model and a computational fluid dynamics (CFD) model to calculate a corresponding coordinate in the three-dimensional city model, thereby calculating, via a simulator, coordinates of the toxic chemical proceeding by hour, which is discharged from a corresponding site based on wind field data (calculated via CFD modeling), and visualizing a simulation result into a dispersion flow of the toxic chemical. The present invention can shorten an amount of time to simulate a predicted path caused by toxic chemical discharge.
