Violent Wave Impacts and Loadings using the delta-SPH method

Modelling of physical problems with violent impacts and strong fluid-structure interaction often represents a demanding challenge for many numerical schemes. The main difficulties arise from the occurrence of large deformations of the air-water interface (due to wave breaking events) and from the imposition of the boundary conditions along it. Differently from mesh-based schemes (which need specific techniques to model the free-surface evolution), particle methods can directly track the air-water interface thanks to their Lagrangian structure.
