A convergent post-processed discontinuous Galerkin method for incompressible flow with variable density
Buyang Li, Weifeng Qiu, ZongZe Yang
We propose a linearized semi-implicit and decoupled finite element method for the incompressible Navier--Stokes equations with variable density. Our method is fully discrete and sh…

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…
