Learning the Exact Flux: Neural Riemann Solvers with Hard Constraints
Yucheng Zhang, Chayanon Wichitrnithed, Shukai Cai +3
Godunov-type methods, which obtain numerical fluxes through local Riemann problems at cell interfaces, are among the most fundamental and widely used numerical methods in computati…
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…
