Parallel Godunov smoothed particle hydrodynamics (SPH) with improved treatment of Boundary Conditions and an application to granular flows
TL;DR: An enhanced conservative Godunov SPH based on the work of Inutsuka is presented that accurately resolves discontinuities without the need to use artificial viscosity, preserves partition of unity everywhere in the domain, correctly and flexibly enforces necessary essential and frictional slip boundary conditions to approximately solve free-surface granular flows.

Numerical studies to propose a ghost particle removed SPH (GR-SPH) method
Alireza Eslamian,M. Khayat +1 more
TL;DR: This paper shows how the use of ghost boundary particles can violate the continuity equation in problems with non-zero velocity divergence and proposes a novel ghost particle removed SPH (GR-SPH) method that discards all ghost particles and artificial forces at the boundaries.
