On the penalty stabilization mechanism for upwind discontinuous Galerkin formulations of first order hyperbolic systems

Jesse Chan, T. Warburton

Penalty fluxes are dissipative numerical fluxes for high order discontinuous Galerkin (DG) methods which depend on a penalization parameter. We investigate the dependence of the sp…

A GPU-accelerated nodal discontinuous Galerkin method with high-order absorbing boundary conditions and corner/edge compatibility

Axel Modave, Andreas Atle, Jesse Chan +1

Discontinuous Galerkin finite element schemes exhibit attractive features for accurate large-scale wave-propagation simulations on modern parallel architectures. For many applicati…

GPU Acceleration of Hermite Methods for the Simulation of Wave Propagation

Arturo Vargas, Jesse Chan, Thomas Hagstrom +1

The Hermite methods of Goodrich, Hagstrom, and Lorenz (2006) use Hermite interpolation to construct high order numerical methods for hyperbolic initial value problems. The structur…

Weight-adjusted discontinuous Galerkin methods: curvilinear meshes

Jesse Chan, Russell J. Hewett, T. Warburton

Traditional time-domain discontinuous Galerkin (DG) methods result in large storage costs at high orders of approximation due to the storage of dense elemental matrices. In this wo…

Weight-adjusted discontinuous Galerkin methods: wave propagation in heterogeneous media

Jesse Chan, Russell J. Hewett, T. Warburton

Time-domain discontinuous Galerkin (DG) methods for wave propagation require accounting for the inversion of dense elemental mass matrices, where each mass matrix is computed with…

Reduced storage nodal discontinuous Galerkin methods on semi-structured prismatic meshes

Jesse Chan, Zheng Wang, Russell J. Hewett +1

We present a high order time-domain nodal discontinuous Galerkin method for wave problems on hybrid meshes consisting of both wedge and tetrahedral elements. We allow for verticall…
