A fast moving least squares approximation with adaptive Lagrangian mesh refinement for large scale immersed boundary simulations [PDF]
Journal of Computational Physics, 2018 In this paper we propose and test the validity of simple and easy-to-implement algorithms within the immersed boundary framework geared towards large scale simulations involving thousands of deformable bodies in highly turbulent flows.

The Improved Element-Free Galerkin Method for 3D Helmholtz Equations
Mathematics, 2021 The improved element-free Galerkin (IEFG) method is proposed in this paper for solving 3D Helmholtz equations. The improved moving least-squares (IMLS) approximation is used to establish the trial function, and the penalty technique is used to enforce ...

An improved smoothed particle hydrodynamics approach using new inverse kernel function
Journal of Ocean Engineering and Science, 2022 The main limitation of Smoothed Particle Hydrodynamics (SPH) method that resists the method's potential is its lack of providing stability and accuracy to the numerical technique.

Transient thermal analysis of functionally graded shallow shells by the MLPG [PDF]
Computer Methods in Materials Science, 2009 A meshless local Petrov-Galerkin (MLPG) method is applied to solve problems of Reissner-Mindlin shells under a transient thermal load. Functionally graded materials with a continuous variation of properties in the shell thickness direction are considered
