[Abstract] Meshfree methods have experimented an important improvement in the last decade.
Actually, we can say that the emerging meshless technology constitutes the most
promising tool to simulate complex problems in the fluid dynamics area. In this
paper we present a formulation which combines a Lagrangian description of the
fluid movement (following the spirit of Smoothed Particle Hydrodynamics and
Vortex Particle Methods) with a Galerkin formulation and Moving Least-Squares
approximation. The performance of the methodology proposed is shown through
various dynamic simulations, demonstrating the attractive ability of particle methods
to handle severe distortions and complex phenomena.
