GPU-acceleration of the Discontinuous Galerkin Shallow Water Equations Model (DG-SWEM) with OpenACC
Chayanon Wichitrnithed, Eirik Valseth, Ethan J. Kubatko +2
This paper presents a porting of {DG-SWEM}, a first-order discontinuous Galerkin solver for storm surge based on the Advanced Circulation Model (ADCIRC), to NVIDIA GPUs. Time-expli…
Coupled Continuous-Discontinuous Galerkin Finite Element Solver for Compound Flood Simulations
Chayanon Wichitrnithed, Eirik Valseth, Shintaro Bunya +2
Several recent tropical cyclones, e.g., Hurricane Harvey (2017), have lead to significant rainfall and resulting runoff. When the runoff interacts with storm surge, the resulting f…
Adaptive hierarchic transformations for dynamically -enriched slope-limiting over discontinuous Galerkin systems of generalized equations
C. Michoski, C. Mirabito, C. Dawson +3
We study a family of generalized slope limiters in two dimensions for Runge-Kutta discontinuous Galerkin (RKDG) solutions of advection--diffusion systems. We analyze the numerical…
