HULL User Guide for Three-Dimensional Linking with EPIC 3

Abstract

This report documents the development of the HULL Eulerian hydrocode as a three-dimensional link to provide time-dependent boundary conditions to the Lagrangian EPIC3 code. During a linked calculation, the penetrator and target are represented in the HULL Eulerian mesh and the calculation is carried to target perforation. After perforation, the data collected in the Eulerian mesh is used as velocity boundary conditions to drive the nodes of the EPIC3 penetrator definition. This two-step procedure is more efficient than a single Eulerian or Lagrangian calculation, since the Eulerian code can be optimally run to handle the severe distortions and deformations during perforation, and a well defined representation of the penetrator can be used in the course of the Lagrangian calculation at late times when slower deformation processes are dominant.
