The Application of Eulerian and Lagrangian Hydrodynamic Computer Codes to Desk-Top Personal Computers

Abstract

Recent advancements in personal computer hardware indicate that sufficient memory, disk storage, and processing speed exist to make the operation of both Eulerian and Lagrangian hydrocodes practical, and considerably less expensive. A limited investigation was conducted to evaluate the ease with which several public domain codes could be adapted to run on 386/486 machines, and whether they would operate with sufficient accuracy and speed. Three codes were selected: (1) HELP, a multi-material Eulerian program for compressible fluid and elastic-plastic flows; (2) NIKE, an implicit finite-deformation, finite-element code; and (3) DYNA, an explicit finite element and finite difference code. All of these codes readily adapted to the personal computer hardware. Issues and code modification approaches are discussed. Example runs are presented.
