MODELING OF SHOCK WAVE AND DYNAMIC INTERACTIONS ON PC BASED COMPUTERS

M. Murphy , C. Cline

The implementation and utility of 80386/80486 personal computer (PC) versions of the Lawrence Livermore National Laboratory developed DYNA and NIKE finite element codes are described and evaluated in this paper. These code conversions provide for the PC modeling of problems that are currently analyzed on mainframes, mini-computers, and workstations. A comprehensive conversion of the entire source code allows for simulation of all problems that can be run on the CRAY, VMS, and UNIX systems. Some advantages of this approach are lower hardware and software costs, a convenient upgrade path for existing PC users, and simplicity for novice or casual users that do not have the time or inclination to learn UNIX. In addition, low cost speed improvements are easily implemented with the addition of the 3167/4167 numeric co-processors from Weitek or with the more expensive board-based I-860 chip options.
