Analysis of a finite element method for linear elasticity with Dirichlet and mixed boundary conditions

Hongpeng Li, Xu Li, Hongxing Rui

In this paper, we investigate a low-order robust numerical method for the linear elasticity problem. The method is based on a Bernardi--Raugel-like -c…

On efficient linear and fully decoupled finite difference method for wormhole propagation with heat transmission process on staggered grids

Xiaoli Li, Ziyan Li, Hongxing Rui

In this paper, we construct an efficient linear and fully decoupled finite difference scheme for wormhole propagation with heat transmission process on staggered grids, which only…

An EMA-conserving, pressure-robust and Re-semi-robust reconstruction method for the unsteady incompressible Navier-Stokes equations

Xu Li, Hongxing Rui

Proper EMA-balance (E: kinetic energy; M: momentum; A: angular momentum), pressure-robustness and -semi-robustness (: Reynolds number) are three important properties of Nav…

A low order divergence-free H(div)-conforming finite element method for Stokes flows

Xu Li, Hongxing Rui

In this paper, we propose a discretization of the Stokes equations on general simplicial meshes in two/three dimensions (2D/3D), which yields an exact…

A Stabilized Hybrid Mixed Finite Element Method for Poroelasticity

Chunyan Niu, Hongxing Rui, Xiaozhe Hu

In this work, we consider a hybrid mixed finite element method for Biot's model. The hybrid P1-RT0-P0 discretization of the displacement-pressure-Darcy's velocity system of Biot's…
