The Mathematics of Smoothed Particle Hydrodynamics (SPH) Consistency

Abstract: Since its inception Smoothed Particle Hydrodynamics (SPH) has been widely employed as a numerical tool in different areas of science, engineering, and more recently in the animation of fluids for computer graphics applications. Although SPH is still in the process of experiencing continual theoretical and technical developments, the method has been improved over the years to overcome some shortcomings and deficiencies. Its widespread success is due to its simplicity, ease of implementation, and robustness in m… Show more

“…• In most mass-particle meshfree methods, each particle carries a mass and a density. This results in the obvious notion of volume as V i = mi ρi , for mass m and density ρ [34,53]. During the initial particle generation process, masses are distributed to particles in a manner so as to make this method consistent.…”

“…27,28 Despite this, SPH has suffers several drawbacks in comparison with classical FEM. 29,30 In the present study, the particle inconsistency and tensile instability problems are solved by using the kerneral correction though Symmetric Smoothed Particle Hydrodynamics (SSPH) 31,32 and Total Lagrangian formulation in the initial undeformed configuration. 33,34 In the SSPH method defined by Batra and Zhang, 31 the formulation begins by the classical Taylor series expansion of a function u(x)…”

“…Therefore, they maintain quasi-ordered particle distributions even in highly dynamical test problems. Second, approximate volume partitioning is achieved using a large number of neighbors 37 , 38 . Third, non-reflecting outlet boundary conditions are implemented by allowing the particles that leave the Venturi diffuser and enter the outflow zone to move according to an outgoing wave equation for the velocity field.…”
