Resumo
[Abstract] In this paper, we propose a Galerkin-based smoothed particle hydrodynamics (SPH) formulation with
moving least-squares meshless approximation, applied to free surface flows. The Galerkin scheme
provides a clear framework to analyse several procedures widely used in the classical SPH literature,
suggesting that some of them should be reformulated in order to develop consistent algorithms. The
performance of the methodology proposed is tested through various dynamic simulations, demonstrating
the attractive ability of particle methods to handle severe distortions and complex phenomena.
