Convergent finite elements on arbitrary meshes, the WG method
Ran Zhang, Shangyou Zhang
On meshes with the maximum angle condition violated, the standard conforming, nonconforming, and discontinuous Galerkin finite elements do not converge to the true solution when th…

A Locking-Free Weak Galerkin Finite Element Method for Linear Elasticity Problems
Fuchang Huo, Ruishu Wang, Yanqiu Wang +1
In this paper, we introduce and analyze a lowest-order locking-free weak Galerkin (WG) finite element scheme for the grad-div formulation of linear elasticity problems. The scheme…
