Study on 3D simulation software for explosion and impact

In this paper, the 3D simulation software for explosion and impact is developed for the simulation of 3D complex explosion field. The theory and algorithm of the MESH-3D pre-processor code, the MMIC-3D computation code and VISC-3D post-processor code are discussed. Taking flow field of explosion in a group of buildings for example, the explosion flow field after big explosion disasters is numerically simulated using the EXPLOSION-3D software. Some important numerical results are obtained, which are of great value to the prevention and control of explosion disasters.
