Discrete meso-element method was recently introduced to simulate shock processes at meso-scale level with 2D code. In this paper, a 3D Discrete meso-element model, mathematical formulation, and boundary conditions are discussed. For 3D discrete calculation, most CPU time and RAM will spend on checking and storing the neighborhood when the number of elements in the system becomes large. A new "Region Method" was suggested to reduce this problem instead of previous "Window Method." Examples for normal and inclined collision between two spheres are presented with the updated 3D discrete meso-element code.
