Homeland explosive consequence and threat (HExCAT) modeling tool

A computerized method to model consequences of an explosion, comprising:

• (a) receiving, by a computing system, user input including parameters for generating and modeling a scenario, explosion device model, and propagation of hazards and injuries;
• (b) generating, by the computing system, the scenario based on the user input and an iterative subset of scenario parameters, the user input indicating an indoor explosion target or an outdoor explosion target, the generating the scenario further comprising communicating, by the computing system, with geospatial databases, retrieving geospatial data from the geospatial databases, and modeling the geospatial data based on a three-dimensional grid of cells, the computing system discretizing space representing the scenario into the three-dimensional grid of cells;
• (c) generating, by the computing system, an explosive device model based on the user input and an iterative subset of explosive device parameters;
• (d) modeling, by the computing system, propagation of hazards into the scenario based on the user input and an iterative subset of hazard parameters, the computing system applying the hazard parameters to the three-dimensional grid of cells, the hazards corresponding to detonation of the explosive device model;
• (e) modeling, by the computing system, injuries corresponding to the modeling propagation of hazards into the scenario, based on an iterative subset of injury parameters, the modeling injuries comprising applying population density to the three-dimensional grid of cells;
• scenario parameters, the explosive device parameters, the hazard parameters, and the injury parameters being distributions applied to Monte-Carlo probabilistic simulations to generate and model the scenario, the explosion device model, and the propagation of hazards and injuries;
• (f) iterating, by the computing system, based on the iterative subsets of scenario parameters, the explosive device parameters, the hazard parameters, and the injury parameters until the discretized space representing the scenario is covered, thereby generating the scenario, generating the explosive device model, modeling propagation of hazards, and modeling injuries;
• and
• (g) generating, by the computing system, an injury record based on the modeling of injuries corresponding to the iterating.
