Expanding the Tabulated Equation of State Implementations in the FLASH Code for the FPEOS Database

We present the enhancement of the tabulated Equation-of-State (TEOS) capabilities of FLASH, a high-performance computing, finite-volume, radiation magneto-hydrodynamics (MHD) 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 TEOS implementation within the FLASH code to make use of the First Principles Equation of State (FPEOS) database, developed by members of the Center for Matter under Extreme Conditions (CMEC). This improvement provides FLASH with high-fidelity data for the materials relevant to the study of giant impacts, synestias, and planetary and moon formation and evolution.
