Webb15 apr. 2015 · Shaped charge simulation using SPH in cylindrical coordinates Semantic Scholar Purpose – The purpose of this paper is to investigate the applicability of the smoothed particle hydrodynamics (SPH) method in the jet formation process of a cylindrical-shaped charge (CSC). WebbThe name "particle-in-cell" originates in the way that plasma macro-quantities ( number density, current density, etc.) are assigned to simulation particles (i.e., the particle weighting ). Particles can be situated anywhere on the continuous domain, but macro-quantities are calculated only on the mesh points, just as the fields are.
