Adaptive unstructured spacetime meshing for four-dimensional spacetime discontinuous Galerkin finite element methods (2012-02-06)We describe the spacetime discontinuous Galerkin method, a new type of finite-element method which promises dramatic improvement in solution speed for hyperbolic problems. These methods require the generation of spacetime ...
(2010-08-31)Smoothed aggregation-based (SA) algebraic multigrid (AMG) is a popular and effective solver for systems of linear equations that arise from discretized partial differential equations. While SA has been effective over a ...
(2010-01-06)This thesis presents the mathematical derivation and implementation of, and improvements to, the discontinuous Galerkin method (DGM) for solving Maxwell’s equations. Each step leading to the development of a computer ...
