Investigating Forecast Proficiency of Hurricane-Induced Compound Flooding With a Discontinuous Galerkin Shallow Water Equation Solver
Matthew Scarborough, Chayanon Wichitrnithed, Shintaro Bunya +4
Recent severe storms on the U.S. Gulf coast have demonstrated the challenges presented by compound flooding, such as the interactions between rainfall runoff and storm surge. Histo…
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…
A Discontinuous Galerkin Finite Element Model for Compound Flood Simulations
Chayanon Wichitrnithed, Eirik Valseth, Ethan J. Kubatko +3
Recent tropical cyclones, e.g., Hurricane Harvey (2017), have lead to significant rainfall and resulting runoff with accompanying flooding. When the runoff interacts with storm sur…
High-order entropy stable discontinuous Galerkin methods for the shallow water equations: curved triangular meshes and GPU acceleration
Xinhui Wu, Jesse Chan, Ethan Kubatko
We present a high-order entropy stable discontinuous Galerkin (ESDG) method for the two dimensional shallow water equations (SWE) on curved triangular meshes. The presented scheme…
Dynamic p-enrichment schemes for multicomponent reactive flows
C. Michoski, C. Mirabito, C. Dawson +3
We present a family of p-enrichment schemes. These schemes may be separated into two basic classes: the first, called \emph{fixed tolerance schemes}, rely on setting global scalar…
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…
Nonlinearity in Oscillatory Flow over Sand Ripple
Ruma Dutta, Ethan Kubatko
In this report, We investigated the nonlinear phenomena in the study of flow dynamics of velocity component. In our studies, we observed nonlinear term in the vertical component of…
