The discontinuous enrichment method
We propose a nite element based discretization method in which the standard polynomial eld is enriched within each element by a nonconforming eld that is added to it. The enrichment contains free-space solutions of the homogeneous diierential equation that are not represented by the underlying polynomial eld. Continuity of the enrichment across element interfaces is enforced weakly by Lagrange ...
متن کاملConvergence of the Discontinuous Galerkin Method for Discontinuous Solutions
We consider linear first order scalar equations of the form ρt + div(ρv) + aρ = f with appropriate initial and boundary conditions. It is shown that approximate solutions computed using the discontinuous Galerkin method will converge in L[0, T ;L(Ω)] when the coefficients v and a and data f satisfy the minimal assumptions required to establish existence and uniqueness of solutions. In particula...
متن کاملA Relation between the Discontinuous Petrov--Galerkin Method and the Discontinuous Galerkin Method
This paper is an attempt in seeking a connection between the discontinuous Petrov– Galerkin method of Demkowicz and Gopalakrishnan [13,15] and the popular discontinuous Galerkin method. Starting from a discontinuous Petrov–Galerkin (DPG) method with zero enriched order we re-derive a large class of discontinuous Galerkin (DG) methods for first order hyperbolic and elliptic equations. The first ...
متن کاملGeneralized finite element enrichment functions for discontinuous gradient fields
A general GFEM/XFEM formulation is presented to solve two-dimensional problems characterized by C continuity with gradient jumps along discrete lines, such as those found in the thermal and structural analysis of heterogeneous materials or in line load problems in homogeneous media. The new enrichment functions presented in this paper allow solving problems with multiple intersecting discontinu...
متن کاملA Higher-Order Discontinuous Enrichment Method for the Solution of High Péclet Advection-Diffusion Problems on Unstructured Meshes
A higher-order discontinuous enrichment method (DEM) with Lagrange multipliers is proposed for the efficient finite element solution on unstructured meshes of the advection-diffusion equation in the high Péclet number regime. Following the basic DEM methodology, the usual Galerkin polynomial approximation is enriched with free-space solutions of the governing homogeneous partial differential eq...
