SPH Corrección de la deficienccia de límites para la mejora de condiciones de contornos en superficies deformables

Van Jones, Qing Yang, Leigh McCue

Abstract

Smoothed particle hydrodynamics (SPH) is a meshless, Lagrangian CFD method. SPH often utilizes static virtual particles to correct for integral deficiencies that occur near boundaries. These virtual particles, while useful in most cases, can be difficult to implement for objects which experience large deformations. As an alternative to virtual particles, a repulsive force algorithm is presented which loosely emulates the presence of virtual particles in the SPH momentum equation.
