Adaptive spacetime meshing for discontinuous Galerkin methods
Spacetime-discontinuous Galerkin (SDG) finite element methods are used to solve hyperbolic spacetime partial differential equations (PDEs) to accurately model wave propagation phenomena arising in important applications in science and engineering. Tent Pitcher is a specialized algorithm, invented by Üngör and Sheffer [2000], and extended by Erickson et al. [2005], to construct an unstructured s...
متن کاملSpacetime Meshing for Discontinuous Galerkin Methods
Spacetime discontinuous Galerkin (DG) methods are used to solve hyperbolic partial differential equations (PDEs) describing wavelike mechanical phenomena. Given a simplicially meshed space domain M ⊂ R, the TentPitcher algorithm developed by [65] and [25] is an advancing front algorithm to incrementally construct a simplicial mesh of the spacetime domain M × [0,∞) ⊂ R that supports an efficient...
متن کاملAdaptive Unstructured Spacetime Meshing for Four-dimensional Spacetime Discontinuous Galerkin Finite Element Methods
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 meshes that satisfy a special causality constraint. This work focuses on the extension of the existing 2d×time spacetime meshing algorithm known as TentPitcher to 3d×time prob...

متن کاملRiemann solutions for spacetime discontinuous Galerkin methods
Spacetime discontinuous Galerkin finite element methods [1–3] rely on ‘target fluxes’ on elementboundaries that are computed via local one-dimensional Riemann solutions in the direction normal toelement face. In this work, we demonstrate a generalized solution procedure for linearized hyperbolicsystems based on diagonalisation of the governing system of partial differential equa...
