Pressure as a function of density for overdriven experimental gas-gun data compared to thermochemical EOSs. The Magpie result (black) agrees with both recent and historic experiments (points) and with LLNL’s Chee-Utah (green dashed) at lower pressures.

Thermochemical code produces high quality and reliable high-explosive equation of state

Magpie has the ability to predictively generate High Explosive (HE) equations of state (EOS). The code’s software design allows for quick and easy implementation of new EOS models.

This will allow for advances in EOS modeling of not just molecular fluids, but the EOS of almost any substance.

Magpie leverages powerful techniques of equilibrium statistical thermodynamics to build EOSs from microscopic level knowledge of atomic and molecular properties.
