Expanding the Tabulated Equation-of-State Implementations in the FLASH Code for the SESAME Database
POSTER
Abstract
We present the enhancement of the tabulated equation-of-state (EOS) capabilities of FLASH, a high-performance computing, finite-volume radiation magnetohydrodynamics code developed by the Flash Center for Computational Science. FLASH has extended physics capabilities that enable the code to treat a broad range of physical processes in astrophysics, laboratory plasma physics, and high-energy-density physics (HEDP). Here we extend the tabulated EOS implementation of the FLASH code to make use of the SESAME EOS database (LAUR-92-3407), generated and curated by the Los Alamos National Laboratory. This improvement provides FLASH with high-fidelity data for the materials used in laser-driven and pulsed-power-driven experiments. We verify the new capability with benchmark HEDP problems and show how they favorably compare against FLASH's previous tabulated EOS implementations.
