A Subroutine to Isolate Material Packages in the HELP (Hydrodynamic Elastic Plastic) Hydrodynamic Code,

Abstract

The Eulerian hydrodynamic code HELP is being used at MRL to model the behavior of warheads. One of the most frequent problems experienced with the code is a breakdown of the pressure iteration in mixed cells where two materials have very disparate densities and/or masses: this occurs often when explosive-metal interactions are modelled. This report describes an addition to the code which allows the removal of gases or other materials once their effects become insignificant. (Author)
