Hybridizable discontinuous Galerkin method for curved domains

In this work we present a technique to numerically solve partial differential equations (PDE’s) defined in general domains Ω. It basically consists in approximating the domain Ω by polyhedral subdomains Dh and suitably defining extensions of the solution from Dh to Ω. More precisely, we solve the PDE in Dh by using a numerical method for polyhedral domains. In order to do that, the boundary con...

A hybridizable discontinuous Galerkin method for time-harmonic Maxwell’s equations

In this paper, we study a bybridizable discontinuous Galerkin (HDG) method for the numerical solution of 2D time-harmonic Maxwell’s equations. The formulations are given, and the relationship between the HDG scheme and the upwind flux DG method is also examined. The presented numerical results show the effectiveness of the proposed HDG method especially in comparison to the upwind flux DG metho...

A Hybridizable and Superconvergent Discontinuous Galerkin Method for Biharmonic Problems

In this paper, we introduce and analyze a new discontinuous Galerkin method for solving the biharmonic problem ∆u = f . The method has two main, distinctive features, namely, it is amenable to an efficient implementation, and it displays new superconvergence properties. Indeed, although the method uses as separate unknowns u, ∇u, ∆u and ∇∆u, the only globally coupled degrees of freedom are thos...

On the Local Discontinuous Galerkin Method for Linear Elasticity

Following Castillo et al. 2000 and Cockburn 2003 , a general framework of constructing discontinuous Galerkin DG methods is developed for solving the linear elasticity problem. The numerical traces are determined in view of a discrete stability identity, leading to a class of stable DG methods. A particular method, called the LDG method for linear elasticity, is studied in depth, which can be v...
