Numerical Blast Simulation Methods and Systems Thereof

摘要

Numerical blast simulation methods and systems are disclosed. SPH model containing a plurality of SPH particles representing a physical domain is received. Each SPH particle is associated with an influence function having a domain of influence. Blast source model containing at least one simulated gas particle is created. The blast source model, defined by a set of explosion characteristics, represents the explosion just before impacting the physical domain. Each simulated gas particle is associated with a set of properties that includes a mass, a velocity vector and a location. Numerically calculated domain behaviors in response to the explosion are obtained by conducting a time-marching simulation for a predetermined duration in a plurality of solution cycles using the SPH model and the blast source model, the domain behaviors are a result of combined interactions between said each simulated gas particle and a corresponding subgroup of the SPH particles.
