A residual based A POSTERIORI error estimator for an augmented mixed finite element method in linear elasticity [PDF]

open access: yes, 2005
In this paper we develop a residual based a posteriori error analysis for an augmented mixed finite element method applied to the problem of linear elasticity in the plane. More precisely, we derive a reliable and efficient a posteriori error estimator

A finite point algorithm for soil water-salt movement equation

open access: yesAdvances in Difference Equations, 2021
In this paper, we propose the meshless finite point method for solving a type of fluid flow problem. The moving least square function is combined with the collocation method to treat nonlinear one- and two-dimensional soil water-salt movement equations ...

On the convergence of adaptive nonconforming finite element methods for a class of convex variational problems [PDF]

open access: yes, 2011
We formulate and analyze an adaptive nonconforming finite element method for the solution of convex variational problems. The class of minimization problems we admit includes highly singular problems for which no Euler–Lagrange equation (or inequality ...

Parallel self-adaptive hp finite element method with shared data structure [PDF]

open access: yesComputer Methods in Materials Science, 2011
In this paper we present a new parallel algorithm of the self-adaptive hp Finite Element Method (hp-FEM) with shared data structures. The algorithm generates in a fully automatic mode (without any user interaction) a sequence of meshes delivering ...
