Numerical Algorithms in a Lagrangian Hydrocode.

Abstract

This report documents the numerical algorithms used in an explicit Lagrangian finite element hydrocode. One, two, and three dimensional implementations of the numerical solution of the conservation equations are covered. Triangular and tetrahedral continuum elements and shell elements are described. SPH (Smooth Particle Hydrodynamics) techniques are discussed. Slideline techniques are explained. Material models are presented for constitutive behavior and equation of state behavior for several categories of materials. This report is a comprehensive presentation of the numerical techniques used in a current production hydrocode.
