Stochastic Discontinuous Galerkin Methods (SDGM) based on fluctuation-dissipation balance

open access: yesResults in Applied Mathematics, 2019
We introduce a general framework for approximating parabolic Stochastic Partial Differential Equations (SPDEs) based on fluctuation-dissipation balance. Using this approach we formulate Stochastic Discontinuous Galerkin Methods (SDGM).

Discontinuous Galerkin finite element methods for radiative transfer in spherical symmetry [PDF]

open access: yes, 2016
The discontinuous Galerkin finite element method (DG-FEM) is successfully applied to treat a broad variety of transport problems numerically. In this work, we use the full capacity of the DG-FEM to solve the radiative transfer equation in spherical ...

The Dual Characteristic-Galerkin Method

open access: yesComptes Rendus. Mathématique
The Dual Characteristic-Galerkin method (DCGM) is conservative, precise and experimentally positive. We present the method and prove convergence and $L^2$-stability in the case of Neumann boundary conditions. In a 2D numerical finite element setting (FEM)

Shock capturing for discontinuous galerkin methods

open access: yes, 2023
Aquesta tesi doctoral proposa formulacions de Galerkin Discontinu (DG) d’alt ordre per la captura de shocks, obtenint alhora solucions altament precises per problemes de flux compressible. En les últimes dècades, la investigació en els mètodes de DG ha estat en constant creixement.

The Time Discontinuous H1-Galerkin Mixed Finite Element Method for Linear Sobolev Equations

open access: yesDiscrete Dynamics in Nature and Society, 2015
We combine the H1-Galerkin mixed finite element method with the time discontinuous Galerkin method to approximate linear Sobolev equations. The advantages of these two methods are fully utilized.

Discontinuous Galerkin Methods on hp-Anisotropic Meshes I: A Priori Error Analysis [PDF]

open access: yes, 2006
We consider the a priori error analysis of hp-version interior penalty discontinuous Galerkin methods for second-order partial differential equations with nonnegative characteristic form under weak assumptions on the mesh design and the local finite ...

A Framework for Curved Boundary Representation in 2D Discontinuous Galerkin Euler Solvers

open access: yesJournal of Applied Fluid Mechanics, 2014
Finite-element based CFD solvers like the family of Discontinuous Galerkin (DG) solvers suffer severely from inaccurate boundary reconstruction. In this matter, developing an accurate and flexible strategy is highly demanded to provide high-order curved ...
