Abstract

In the present study, a body-fitted and uniform initial particle arrangement method is proposed for mesh-free methods, such as SPH, MPS, and LSMPS. Single-layer boundary particles with/without normal direction vectors and multilayer boundary particles can be successfully generated. Typical tests show that the proposed method can successfully generate body-fitted and uniform initial particle distributions. Numerical simulation results using the generated initial particle distributions obtained satisfied results. It is then verified that the present method can be usefully and robustly for mesh-free particle simulations.
