High-Order Finite Elements for Thermal Radiative Transfer on Curved Meshes

Terry Haut | 18-ERD-002

Executive Summary

We are developing numerical methods for high-order thermal radiative transport for incorporation into hydrodynamics codes to improve and expand the Laboratory’s current simulation capabilities. This research will also enable current codes to run in an exascale environment, maintaining the currency of the simulation capabilities underlying several key national missions.
