Classification and Overview of Meshfree Methods [PDF]
, 2004 This paper gives an overview over Meshfree Methods. Starting point is an extended and modified classification of Meshfree Methods due to three aspects: The construction of a partition of unity, the choice of an approximation either with or without using ...

A flux conserving meshfree method for conservation laws
, 2022 S.238-256Lack of conservation has been the biggest drawback in meshfree generalized finite difference methods(GFDMs). In this paper, we present a novel modification of classical meshfree GFDMs to include local balances which produce an approximate ...

Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing
Advanced Science, EarlyView.Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...

On a Meshfree Method for Singular Problems
Computer Modeling in Engineering & Sciences, 2002 Interests in meshfree (or meshless) methods have grown rapidly in the recent years in solving boundary value problems arising in mechanics, especially in dealing with difficult problems involving large deformation, moving discontinuities, etc. Rigorous error estimates of a meshfree method, the reproducing kernel particle method, for smooth solutions ...
