Meshless Singular Boundary Method for Nonlinear Sine‐Gordon Equation
Mathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018 A meshless method based on the singular boundary method is developed for the numerical solution of the time‐dependent nonlinear sine‐Gordon equation with Neumann boundary condition. In this method, by using a time discrete scheme to approximate the time derivatives, the time‐dependent nonlinear problem is transformed into a sequence of time‐independent

Assessment of implicit adaptive mesh‐free CFD modelling
International Journal for Numerical Methods in Fluids, Volume 96, Issue 5, Page 670-700, May 2024.The paper shows results from an implicit meshless method suitable for the analysis of external aerodynamic flows. This research is using a cloud of points instead of cells, and several stencils are compared for the discretization of the flow equations, along with a least‐squares method.

A General 2D Meshless Interpolating Boundary Node Method Based on the Parameter Space
Mathematical Problems in Engineering, Volume 2017, Issue 1, 2017., 2017 The presented study proposed an improved interpolating boundary node method (IIBNM) for 2D potential problems. The improved interpolating moving least‐square (IIMLS) method was applied to construct the shape functions, of which the delta function properties and boundary conditions were directly implemented.

Mathematical Problems in Engineering, Volume 2016, Issue 1, 2016., 2016 A numerical analysis of the space‐fractional wave equation is carried out by the improved moving least‐square Ritz (IMLS‐Ritz) method. The trial functions for the space‐fractional wave equation are constructed by the IMLS approximation. By the Galerkin weak form, the energy functional is formulated.

Meshless local Petrov-Galerkin (MLPG) method in combination with finite element and boundary element approaches [PDF]
Computational Mechanics, 2000 Combinations of the meshless local Petrov-Galerkin (MLPG) method with finite element (FE) and boundary element (BE) methods are proposed for elasticity boundary value problems with the aim to improve the solution efficiency. Special interface elements are needed along the border of MLPG and FE (or BE) regions in order to satisfy the displacement ...

Mathematical Problems in Engineering, Volume 2016, Issue 1, 2016., 2016 An RBF‐based meshless method is presented for the analysis of thin plates undergoing large deflection. The method is based on collocation with the multiquadric radial basis function (MQ‐RBF). In the proposed method, the resulting coupled nonlinear equations are solved using an incremental‐iterative procedure.
