Conforming Discrete Gradgrad-Complexes in Three Dimensions
Jun Hu, Yizhou Liang
In this paper, the first family of conforming discrete three dimensional Gradgrad-complexes consisting of finite element spaces is constructed. These discrete complexes are exact i…
Finite Element Methods For Interface Problems On Local Anisotropic Fitting Mixed Meshes
Jun Hu, Hua Wang
A simple and efficient interface-fitted mesh generation algorithm is developed in this paper. This algorithm can produce a local anisotropic fitting mixed mesh which consists of bo…
Preconditioned Legendre spectral Galerkin methods for the non-separable elliptic equation
Xuhao Diao, Jun Hu, Suna Ma
The Legendre spectral Galerkin method of self-adjoint second order elliptic equations usually results in a linear system with a dense and ill-conditioned coefficient matrix. In thi…
3D -nonconforming tetrahedral finite elements for the biharmonic equation
Jun Hu, Shudan Tian, Shangyou Zhang
In this article, a family of -nonconforming finite elements on tetrahedral grids is constructed for solving the biharmonic equation in 3D. In the family, the polynomi…
Asymptotically exact a posteriori error estimates of eigenvalues by the Crouzeix-Raviart element and enriched Crouzeix-Raviart element
Jun Hu, Limin Ma
Two asymptotically exact a posteriori error estimates are proposed for eigenvalues by the nonconforming Crouzeix--Raviart and enriched Crouzeix-- Raviart elements. The main challen…
Asymptotic expansions of eigenvalues by both the Crouzeix-Raviart and enriched Crouzeix-Raviart elements
Jun Hu, Limin Ma
Asymptotic expansions are derived for eigenvalues produced by both the Crouzeix-Raviart element and the enriched Crouzeix--Raviart element. The expansions are optimal in the sense…
