Combined Eulerian-Lagrangian or Pseudo-Lagrangian Descriptions of Waves Caused by an Advancing Free Surface Disturbance

We develop a new methodology for the numerical modeling of nonlinear free surface waves, caused by an advancing free surface disturbance, based on combining Lagrangian and Eulerian, or pseudoLagrangian, methods for the time updating of free surface geometry and motion. We solve potential flow equations with a threedimensional (3D) higher-order Boundary Element Method (BEM; Grilli et al., 2000, ...

3-D numerical analysis of orthogonal cutting process via mesh-free method

In this paper, the applications of mesh-free SPH (Smoothed Particle Hydrodynamics) methodology to the simulation and analysis of 3-D hard machining process is presented. A Langrangian SPH based model is carried out using the Ls-Dyna software. Classical Lagrangian, Eulerian and ALE methods such as finite element methods (FEM) cannot resolve the large distortions very well. Conventional finite el...

Lagrangian versus Eulerian integration errors

The possibility to use a Lagrangian frame to solve problems with large time-steps was successfully explored previously by the authors for the solution of homogeneous incompressible fluids and also for solving multi-fluid problems [28-30]. The strategy used by the authors was named Particle Finite Element Method second generation (PFEM-2). The objective of this paper is to demonstrate in which c...

To mesh or not to mesh.

We are in the midst of an increasingly acrimonious discussion regarding the use of mesh in pelvic reconstructive surgery. Modern mesh kits, aggressively marketed by biotech companies, have become widespread. At times, they are used inappropriately, and significant complications such as pain syndromes and erosion are not uncommon. While conventional alternatives such as sacrospinous colpopexy an...
