Particle packing algorithm for sph schemes
WebUsing some intrinsic features of the Smoothed Particle Hydrodynamics schemes (SPH), an innovative algorithm for the initialization of the particle distribution has been defined. Webis uniform. Moreover, SPH schemes typically require the mass or volume to be constant for all particles. For a uniform density, this necessitates a good initial particle distribution. In this paper, various particle packing algorithms present in literature are implemented and compared with the in-
