Moving least-squares corrections for smoothed particle hydrodynamics
Annals of Geophysics, 2011 First-order moving least-squares are typically used in conjunction with smoothed particle hydrodynamics in the form of post-processing filters for density fields, to smooth out noise that develops in most applications of smoothed particle hydrodynamics ...

Meshfree volume-averaged nodal projection method for nearly-incompressible elasticity using meshfree and bubble basis functions [PDF]
, 2015 peer reviewedWe present a displacement-based Galerkin meshfree method for the analysis of nearly-incompressible linear elastic solids, where low-order simplicial tessellations (i.e., 3- node triangular or 4-node tetrahedral meshes) are used as a ...

Least-Squares Meshfree Method and Integration Error [PDF]
, 2001 Least-squares meshfree method is presented. Conventional meshfree methods based on the Galerkin formulation suffer from inaccurate numerical integration. Least-squares formulation exhibits rather different integration-related characteristics.

Volume and Mass Conservation in Lagrangian Meshfree Methods [PDF]
Meshfree Lagrangian frameworks for free surface flow simulations do not conserve fluid volume. Meshfree particle methods like SPH are not mimetic, in the sense that discrete mass conservation does not imply discrete volume conservation. On the other hand,

Meshfree Modelling of Hyperelastic Mechanics [PDF]
, 2020 Large deformation mechanics faces numerous challenges when simulated using mesh-based methods, notably the finite element method. Firstly, the computational modeler is required to fit a mesh to the body of interest, which is a tedious and time-consuming ...
