The method of Smoothed Particle Hydrodynamics (SPH) is used for the numerical simulation of compaction of iron powder. The character of SPH allows for accurately tracking relevant material properties within a Lagrangian coordinate system without the problems due to limited mesh deformation allowed by the fixed connectivity of the Finite Element Method (FEM).
