Magpie: A new thermochemical code

Abstract

Here we outline the methods used in LANL's thermochemical equation of state modeling code. We lay out the basic numerical modeling used to describe equilibrium molecular fluid equation of state. We look at an example of PBX-9501 and find good agreement between experiments and other theoretical modeling. This work serves as the basis from which we will further develop modeling of reactive matter equation of state for materials such as high explosives.
