Radial basis function based meshless methods for fluid flow problems
, 2006 This thesis is concerned with the development of meshless methods using radial basis functions for solving fluid flow problems. The advantage of meshless methods over traditional mesh-based methods is that they make use of a scattered set of collocation ...

A comparison of meshless and finite element approaches to ductile damage in forming processes [PDF]
Computer Methods in Materials Science, 2007 In this work the ability and versatility of a meshless method, namely the Reproducing Kernel Particle Method, is assessed in the modelling of ductile damage in forming processes. The performance is compared with a traditional finite element approach.

A Unified Block‐Modal Framework for Inverse Source Problems in Heat and Mass Transfer
International Journal for Numerical Methods in Engineering, Volume 127, Issue 19, 15 October 2026.ABSTRACT This work presents a unified block–modal framework for inverse source identification in linear diffusive problems arising in heat and mass transfer. Starting from a general parabolic model with mixed boundary operators, the Classical Integral Transform Technique is employed to project the dynamics onto an orthonormal eigenbasis, yielding a ...

Meshless Modelling of Laminate Mindlin Plates under Dynamic Loads
Communications, 2012 Collocation method and Galerkin method have been dominant in the existing meshless methods. A meshless local Petrov-Galerkin (MLPG) method is applied to solve laminate plate problems described by the Reissner-Mindlin theory for transient dynamic loads ...

The MLPG analysis of crack problems in magnetoelectroelastic solids [PDF]
Computer Methods in Materials Science, 2011 A meshless method based on the local Petrov-Galerkin approach is applied for boundary value problems with cracks in magnetoelectroelastic solids. A unit step function is used as the test functions in the local weak-form.

On the Numerical Solution of the Poisson Equation in the Smoothed Particle Hydrodynamics
Studies in Applied Mathematics, Volume 157, Issue 4, October 2026.ABSTRACT In the present work, we address some aspects related to the numerical solution of the Poisson equation within the framework of the Smoothed Particle Hydrodynamics (SPH). In this case, the Poisson equation is solved using nonlocal, kernel‐based discretizations of the differential operators (i.e., gradient, divergence, and Laplacian operators ...

Imposing boundary conditions in the meshless local Petrov–Galerkin method
IET Science, Measurement & Technology, 2008 A particular meshless method, named meshless local Petrov-Galerkin is investigated. To treat the essential boundary condition problem, an alternative approach is proposed. The basic idea is to merge the best features of two different methods of shape function generation: the moving least squares (MLS) and the radial basis functions with polynomial ...

Maximum‐Entropy‐Based Meshless Modeling of Surface‐Tension‐Driven Large Deformation
International Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.ABSTRACT Soft material modeling is challenging due, among others, to the substantial structural changes these materials undergo. In this context, meshless methods offer a promising alternative to overcome the limitations of established mesh‐based approximations such as finite elements. However, they introduce new challenges.
