The anticipated impact of supercomputers on finite-element analysis

The supercomputers of the 1980's have already impacted large-scale computation. This paper discusses the status and anticipated impact of supercomputers on finite-element analysis which is the primary tool for structural analysis and is also very useful in other areas of engineering analysis. The initial impact has been the significant reduction in turnaround time for large problems and the corresponding opportunity to solve heretofore unsolvable problems. In these cases, emphasis has been placed on employing already-proven computing software which was modifed to take advantage of vector processing and other forms of parallel operations. This trend is expected to continue because the established usage base of commercially available programs is not likely to be quickly dislodged. The near term will see the further use of design optimization, broader use of nonlinear mechanics, and a closer link between designers and analysts because of improved computer turnaround. The economy of scale suggests that solution techniques will be performed not only faster but cheaper than is possible with scalar processors which will further encourage the analysis of larger, more complex structures. The supercomputers of the future are expected to offer additional challenges to today's application systems. A primary factor in this will be the effective use of multiprocessors. Additional influence is expected as Artificial Intelligence matures to the point where Expert Systems become a reality for selected engineering and scientific disciplines. In order to effectively compete, today's software companies must address the possibility of significant changes in the architecture and methodology currently embodied in today's systems. Improved packaging, most likely in the form of pre- and postprocessors, will be necessary to provide industry- or technology-specific systems solutions.
