A discontinuous Galerkin moving mesh method for Hamilton-Jacobi equations [PDF]

open access: yes, 2007
In this paper we consider the numerical solution of first-order Hamilton-Jacobi equations using the combination of a discontinuous Galerkin finite element method and an adaptive $r$-refinement (mesh movement) strategy.

Steady-State Simulation of Semiconductor Devices Using Discontinuous Galerkin Methods

open access: yesIEEE Access, 2020
Design of modern nanostructured semiconductor devices often calls for simulation tools capable of modeling arbitrarily-shaped multiscale geometries. In this work, to this end, a discontinuous Galerkin (DG) method-based framework is developed to simulate ...

Comparison of high-order methods on unstructured grids [PDF]

open access: yes, 2013
A high-order Discontinuous Galerkin (DG) method is formulated and implemented on the Cranfield University’s 3D unstructured Finite Volume Method (FVM) code (UCNS3D), for both linear and non-linear hyperbolic conservation laws and for test-cases which ...

Compact and stable discontinuous Galerkin methods for convection-diffusion problems [PDF]

open access: yes, 2012
We present a new scheme, the compact discontinuous Galerkin 2 (CDG2) method, for solving nonlinear convection-diffusion problems together with a detailed comparison to other well-accepted DG methods.

Spherical Grid Creation and Modeling Using the Galerkin Compiler GC_Sphere

open access: yesAtmosphere, 2023
The construction of spherical grids is, to a large extent, a question of organized programming. Such grids come in the form of rhomboidal/triangular grids and hexagonal grids.

Comparison of implicit time-discretization schemes for hybridized discontinuous Galerkin methods

open access: yesApplied and Computational Mechanics, 2022
The present study is focused on the application of two families of implicit time-integration schemes for general time-dependent balance laws of convection-diffusion-reaction type discretized by a hybridized discontinuous Galerkin method in space, namely ...

Energy consistent discontinuous Galerkin methods for a quasi-incompressible diffuse two phase flow model [PDF]

open access: yes, 2013
We design consistent discontinuous Galerkin finite element schemes for the approximation of a quasi-incompressible two phase flow model of Allen--Cahn/Cahn--Hilliard/Navier--Stokes--Korteweg type which allows for phase transitions.
