Consistent and Meta-Stable Equation of State Models for Hydro and Solid Dynamics

Treating general equations of state, especially for mixtures, is a daunting task and major source of simulation failures for high-energy flows. There is a continuing effort to improve the robustness of flow solvers subject to equation of state errors and deficiencies.

For purely hydrodynamic simulations using real equations of state like SESAME, the overhead for the equation of state (EOS) evaluations is likely to be the single largest factor in the simulation time to completion.
