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…
An Efficient Sweep-based Solver for the Equations on High-Order Meshes
T. S. Haut, P. G. Maginot, V. Z. Tomov +3
We propose a graph-based sweep algorithm for solving the steady state, mono-energetic discrete ordinates on meshes of high-order curved mesh elements. Our spatial discretization co…
Model Structural Inference using Local Dynamic Operators
Anthony M. DeGennaro, Nathan M. Urban, Balasubramanya T. Nadiga +1
This paper focuses on the problem of quantifying the effects of model-structure uncertainty in the context of time-evolving dynamical systems. This is motivated by multi-model unce…
