Though the discontinuous Galerkin method is attracting more and more applications in many
fields due to its local conservation, high-order accuracy, and flexibility for resolving complex …

We consider several methods for generating initial guesses when iteratively solving
sequences of linear systems, showing that they can be implemented efficiently in GPU …

With the collapse of single-processor computing in the high performance computing (HPC)
field, a wave of parallel-computing has emerged. Alongside the paradigm shift of …

To develop a robust, well‐balanced and quadrature‐free Runge‐Kutta discontinuous
Galerkin (RKDG) shallow water solver, we introduce an efficient wetting and drying (WD) …

In dieser Arbeit präsentieren wir ein neues Discontinuous Galerkin Spektrale Elemente
Verfahren hoher Ordnung zur Approximation der nicht-linearen Flachwassergleichungen …

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 …

As finite element discretizations ever grow in size to address real-world problems, there is
an increasing need for fast algorithms. Nowadays there are many GPU/CPU parallel …
