The Energy Conserving Particle-in-Cell Method [PDF]

Journal of Computational Physics, 2011
A new Particle-in-Cell (PIC) method, that conserves energy exactly, is presented. The particle equations of motion and the Maxwell's equations are differenced implicitly in time by the midpoint rule and solved concurrently by a Jacobian-free Newton ...

Local Consistency of Smoothed Particle Hydrodynamics (SPH) in the Context of Measure Theory

Frontiers in Applied Mathematics and Statistics, 2022
The local consistency of the method of Smoothed Particle Hydrodynamics (SPH) is proved for a multidimensional continuous mechanical system in the context of measure theory.

Numerical analysis of biomaterial deformation with non-uniform elasticity for maxillofacial palpation by particle method

Nihon Kikai Gakkai ronbunshu, 2021
Palpation is an important medical skill to find bad lumps or tumors in the first medical examination. However, the practical palpation training has not been conducted enough to avoid patient’s risk in medical educational institutions.

Non-Symmetrical Collapse of an Empty Cylindrical Cavity Studied with Smoothed Particle Hydrodynamics

Applied Sciences, 2021
The non-symmetrical collapse of an empty cylindrical cavity is modeled using Smoothed Particle Hydrodynamics. The presence of a nearby surface produces an anisotropic pressure field generating a high-velocity jet that hits the surface.

Meshfree particle method [PDF]

Proceedings Ninth IEEE International Conference on Computer Vision, 2003
Many of the computer vision algorithms have been posed in various forms of differential equations, derived from minimization of specific energy functionals, and the finite element representation and computation have become the de facto numerical strategies for solving these problems. However, for cases where domain mappings between numerical iterations

A Generalized Interpolation Material Point Method for Shallow Ice Shelves. 2: Anisotropic Nonlocal Damage Mechanics and Rift Propagation

Journal of Advances in Modeling Earth Systems, 2021
Ice shelf fracture is responsible for roughly half of Antarctic ice mass loss in the form of calving and can weaken buttressing of upstream ice flow.

Investigation of the Outflow and Spreading-Solidification Behaviour of Stratified Molten Metal

Journal of Nuclear Engineering, 2021
The spreading-solidification behaviour of the stratified molten metals was investigated. This is important in understanding the practical fuel debris distribution spread and solidified in the primary containment vessel (PCV) of Fukushima Daiichi Nuclear ...

How to Modify LAMMPS: From the Prospective of a Particle Method Researcher

ChemEngineering, 2021
LAMMPS is a powerful simulator originally developed for molecular dynamics that, today, also accounts for other particle-based algorithms such as DEM, SPH, or Peridynamics.

Adaptive resizing-based multi-resolution particle method

Mechanical Engineering Journal, 2021
Multi-resolution techniques are essential for the performance of large-scale simulations of computational fluid dynamics with particle methods. In this study, a novel adaptive multi-resolution scheme has been developed for the least squares moving ...
