A local meshless method for the numerical solution of multi-term time-fractional generalized Oldroyd-B fluid model [PDF]

open access: yesHeliyon
This work presents an accurate and efficient method, for solving a two dimensional time-fractional Oldroyd-B fluid model. The proposed method couples the Laplace transform (LT) with a radial basis functions based local meshless method (LRBFM).

On Interpolative Meshless Analysis of Orthotropic Elasticity

open access: yesBuildings, 2023
As one possible alternative to the finite element method, the interpolation characteristic is a key property that meshless shape functions aspire to. Meanwhile, the interpolation meshless method can directly impose essential boundary conditions, which is

Network element methods for linear elasticity

open access: yesComptes Rendus. Mécanique, 2023
We explain how to derive a network element for the linear elasticity problem. After presenting sufficient conditions on the network for the validity of a discrete Korn inequality, we also propose several variations of the presented method and in ...

A shock-capturing meshless method for solving the one-dimensional Saint-Venant equations on a highly variable topography

open access: yesJournal of Hydroinformatics, 2023
The Saint-Venant equations are numerically solved to simulate free surface flows in one dimension. A Riemann solver is needed to compute the numerical flux for capturing shocks and flow discontinuities occurring in flow situations such as hydraulic jump,
