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)
