A mixed finite element scheme for biharmonic equation with variable coefficient and von Kármán equations
Huangxin Chen, Amiya K. Pani, Weifeng Qiu
In this paper, a new mixed finite element scheme using element-wise stabilization is introduced for the biharmonic equation with variable coefficient on Lipschitz polyhedral domain…
Analysis of a semi-implicit structure-preserving finite element method for the nonstationary incompressible Magnetohydrodynamics equations
Weifeng Qiu, Ke Shi
We revise the structure-preserving finite element method in [K. Hu, Y. MA and J. Xu. (2017) Stable finite element methods preserving exactly for MHD mod…
Adaptive First-Order System Least-Squares Finite Element Methods for Second Order Elliptic Equations in Non-Divergence Form
Weifeng Qiu, Shun Zhang
This paper studies adaptive first-order least-squares finite element methods for second-order elliptic partial differential equations in non-divergence form. Unlike the classical f…
Analysis of an interior penalty DG method for the quad-curl problem
Gang Chen, Weifeng Qiu, Liwei Xu
The quad-curl term is an essential part of the resistive magnetohydrodynamic (MHD) equation and the fourth order inverse electromagnetic scattering problem, which are both of great…
