Abstract
This paper describes the recent advances and applications of the Particle Finite
Element Method (PFEM) for hydrodynamic analysis of port structures under sea
loads taking into account fluid-structure interaction effects. The paper describes
the theoretical basis of the PFEM combining concept from Lagrangian flows,
particle methods and finite element techniques. Emphasis is put on the treatment
of fluid-structure interaction effects allowing for motions and deformation of the
structures under hydrodynamic sea forces.
Examples of the efficiency and accuracy of the PFEM for the analysis of piers
and breakwater structures under different sea loading conditions are presented.
Keywords: Particle Method, Finite Element Method (PFEM), Lagrangian

1 Introduction
Over the last twenty years, computer simulation of incompressible fluid flow has
been solved in different ways. However, it is still difficult to analyze problems in
which the shape of the interface changes continuously or in fluid-structure
interactions with free-surfaces where complicated contact problems are involved.
The PFEM solves the fluid dynamics equations in a Lagrangian framework
with the finite element method. It is also a particle method, as the movement of
