3D Thermal Simulation of a Laser Drilling Process with Meshfree Methods

open access: yesJournal of Manufacturing and Materials Processing, 2020
Numerical simulation of laser drilling is rapidly gaining interest in academia and industry since this process remains one of the most important and widely-used technologies in modern manufacturing.

An advanced meshless method for time fractional diffusion equation [PDF]

open access: yes, 2011
Recently, because of the new developments in sustainable engineering and renewable energy, which are usually governed by a series of fractional partial differential equations (FPDEs), the numerical modelling and simulation for fractional calculus are ...

Multiscale Partition of Unity [PDF]

open access: yes, 2013
We introduce a new Partition of Unity Method for the numerical homogenization of elliptic partial differential equations with arbitrarily rough coefficients. We do not restrict to a particular ansatz space or the existence of a finite element mesh.

Numerical simulation of dry laser derusting process based on SPH method

open access: yesAIP Advances, 2023
Laser cleaning is an efficient, environmental-friendly, and non-contact surface treatment technology. Laser radiation and heating cause the surface material to heat up and gasify, separating it from the substrate. Traditional mesh-based numerical methods

On Meshfree GFDM Solvers for the Incompressible Navier-Stokes Equations

open access: yes, 2017
Meshfree solution schemes for the incompressible Navier--Stokes equations are usually based on algorithms commonly used in finite volume methods, such as projection methods, SIMPLE and PISO algorithms.

Brownian dynamics of rigid particles in an incompressible fluctuating fluid by a meshfree method

open access: yes, 2015
A meshfree Lagrangian method for the fluctuating hydrodynamic equations (FHEs) with fluid-structure interactions is presented. Brownian motion of the particle is investigated by direct numerical simulation of the fluctuating hydrodynamic equations.

GIZMO: A New Class of Accurate, Mesh-Free Hydrodynamic Simulation Methods [PDF]

open access: yes, 2015
We present two new Lagrangian methods for hydrodynamics, in a systematic comparison with moving-mesh, SPH, and stationary (non-moving) grid methods. The new methods are designed to simultaneously capture advantages of both smoothed-particle hydrodynamics

Modeling Grinding Processes—Mesh or Mesh-Free Methods, 2D or 3D Approach?

open access: yesJournal of Manufacturing and Materials Processing, 2022
The objectives of this study are mainly two: (1) to validate whether a single grain scratch process can be modeled in two dimensions under the assumption of plane strain, and (2) to select the best discretization approach to model a single grain scratch ...

Meshfree finite differences for vector Poisson and pressure Poisson equations with electric boundary conditions

open access: yes, 2013
We demonstrate how meshfree finite difference methods can be applied to solve vector Poisson problems with electric boundary conditions. In these, the tangential velocity and the incompressibility of the vector field are prescribed at the boundary.

A mesh-free simulation of mode I delamination of composite structures

open access: yesScience and Engineering of Composite Materials, 2014
A numerical and experimental investigation for the analysis of delamination problem under mode I loading in composite material is presented. Firstly, the simulation of the delamination under mode I loading and failure of composite materials based on the ...
