Seakeeping with the semi-Lagrangian particle finite element method [PDF]
Computational Particle Mechanics, 2016 The application of the semi-Lagrangian Particle Finite Element Method (SL–PFEM) for the seakeeping sim-ulation of the Wave Adaptive Modular Vehicle under spray generating conditions is presented. The time integration of the Lagrangian advection is done using the explicit integra-tion of the velocity and acceleration along the streamlines (X-IVAS ...

Parallel Delaunay triangulation for particle finite element methods [PDF]
Communications in Numerical Methods in Engineering, 2007 AbstractDelaunay triangulation is a geometric problem that is relatively difficult to parallelize. Parallel algorithms are usually characterized by considerable interprocessor communication or important serialized parts. In this paper, we propose a method that achieves high speed‐ups, but needs information regarding locally maximum element ...

The Particle Finite Element Method for Multi-Fluid Flows [PDF]
, 2011 This paper presents the Particle Finite Element Method (PFEM) and its application to multi-fluid flows. Key features of the method are the use of a Lagrangian description to model the motion of the fluid particles (nodes) and that all the information is associated to the particles.
