A short note on the accuracy of the discontinuous Galerkin method with reentrant faces
Will Pazner, Terry Haut
We study the convergence of the discontinuous Galerkin (DG) method applied to the advection-reaction equation on meshes with reentrant faces. On such meshes, the upwind numerical f…
A New Scheme for Solving High-Order DG Discretizations of Thermal Radiative Transfer using the Variable Eddington Factor Method
Ben C. Yee, Samuel S. Olivier, Ben S. Southworth +2
We present a new approach for solving high-order thermal radiative transfer (TRT) using the Variable Eddington Factor (VEF) method (also known as quasidiffusion). Our approach leve…
Diffusion synthetic acceleration for heterogeneous domains, compatible with voids
Ben S. Southworth, Milan Holec, Terry S. Haut
A standard approach to solving the S transport equations is to use source iteration with diffusion synthetic acceleration (DSA). Although this approach is widely used and effec…
A Quadratic Programming Flux Correction Method for High-Order DG Discretizations of SN Transport
Ben C. Yee, Samuel S. Olivier, Terry S. Haut +3
We present a new flux-fixup approach for arbitrarily high-order discontinuous Galerkin discretizations of the SN transport equation. This approach is sweep-compatible: as the trans…
Acceleration of Source Iteration using the Dynamic Mode Decomposition
Ryan G. McClarren, Terry S. Haut
We present a novel acceleration technique for improving the convergence of source iteration for discrete ordinates transport calculations. Our approach uses the idea of the dynamic…
DSA Preconditioning for DG discretizations of transport and High-Order curved meshes
T. S. Haut, B. S. Southworth, P. G. Maginot +1
This paper derives and analyzes new diffusion synthetic acceleration (DSA) preconditioners for the SN transport equation when discretized with a high-order (HO) discontinuous Galer…
