Reference Solutions for Linear Radiation Transport: the Hohlraum and Lattice Benchmarks

Two benchmark problems for linear radiation transport and derived from the literature are presented in detail and several quantities of interest are defined. High-resolution simulations are computed using standard, robust numerical methods and implemented using HPC resources. The goal of these simulations is to provide reference solutions for new discretization approaches, to aid in the development of multi-fidelity uncertainty quantification and optimization algorithms, to provide data for training surrogate models. The code used to perform the simulations and post-process the data is publicly available, as is the raw data that is used to generate the results presented in the paper.
