A Nonlinear Moment Model for Radiative Transfer Equation in Slab Geometry
Yuwei Fan, Ruo Li, Lingchao Zheng
This paper is concerned with the approximation of the radiative transfer equation for a grey medium in the slab geometry by the moment method. We develop a novel moment model inspi…
A Discontinuous Galerkin Method for the Stokes Equation by Divergence-free Patch Reconstruction
Ruo Li, Zhiyuan Sun, Zhijian Yang
A discontinuous Galerkin method by patch reconstruction is proposed for Stokes flows. A locally divergence-free reconstruction space is employed as the approximation space, and the…
A Discontinuous Galerkin Method by Patch Reconstruction for Elliptic Interface Problem on Unfitted Mesh
Ruo Li, Fanyi Yang
We propose a discontinuous Galerkin(DG) method to approximate the elliptic interface problem on unfitted mesh using a new approximation space. The approximation space is constructe…
A finite element method by patch reconstruction for the Stokes problem using mixed formulations
Ruo Li, Zhiyuan Sun, Fanyi Yang +1
In this paper, we develop a patch reconstruction finite element method for the Stokes problem. The weak formulation of the interior penalty discontinuous Galerkin is employed. The…
An Arbitrary-Order Discontinuous Galerkin Method with One Unknown Per Element
Ruo Li, Pingbing Ming, Zhiyuan Sun +1
We propose an arbitrary-order discontinuous Galerkin method for second-order elliptic problem on general polygonal mesh with only one degree of freedom per element. This is achieve…
