A Comparison of Artificial Viscosity, Limiters, and Filters, for High Order Discontinuous Galerkin Solutions in Nonlinear Settings
Craig Michoski,Clint Dawson,Ethan J. Kubatko,Damrongsak Wirasaet,Steven R. Brus,Joannes J. Westerink +5 more
TL;DR: This work uses a discontinuous Galerkin finite element method to study a nonlinear system of advection–diffusion–reaction equations and aspects of its regularity, and presents a family of solutions consisting of a sharp, computationally efficient slope limiter, a standard spectral filter, and a novel artificial diffusion algorithm with a solution-dependent entropy sensor.
Journal ArticleDOI
Unstructured global to coastal wave modeling for the Energy Exascale Earth System Model using WAVEWATCH III version 6.07
TL;DR: A global unstructured mesh capability for the WAVEWATCH III (WW3) model is introduced that is suitable for coupling within the US Department of Energy's Energy Exascale Earth System Model (E3SM).
Journal ArticleDOI
Artificial boundary layers in discontinuous Galerkin solutions to shallow water equations in channels
Damrongsak Wirasaet,Steven R. Brus,Craig Michoski,Ethan J. Kubatko,Joannes J. Westerink,Clint Dawson +5 more
TL;DR: This work considers the application of Discontinuous Galerkin (DG) solutions to open channel flow problems, governed by two-dimensional shallow water equations (SWE), with solid curved wall boundaries on which the no-normal flow boundary conditions are prescribed.
