The objective of this study is to simulate shock wave due to near-field explosion by using Arbitrary-Lagargian-Eulerian (ALE) fluid-structure interaction algorithm in the LS-DYNA finite element analysis software. Overpressure from near-field burst simulation was compared to the U. S. Army Technical Manual TM5-1300, with relative difference of 5%, for a scaled distance from 0.09 to 0.29 m/kg^(1/3). The results showed that LS-DYNA can predict near-field explosion. Furthermore, using LS-DYNA Mapping 2D to 2D technology can effectively increase the numerical model size of which scaled distance can be extended from 0.09 to 0.61 m/kg^(1/3).
