Three-dimensional elasto-static analysis of 100 million degrees of freedom

Abstract GeoFEM, a parallel finite element analysis system, is application software that is being developed for conducting simulations of solid earth. This system is currently run on a massively parallel computer and can perform linear elastic analysis of a simple shape involving up to 100,000,000 degrees of freedom. In the present study, the memory capacity required and elapsed time were estimated for large-scale structural analyses, and the efficiencies were examined to investigate the parallel performance. This paper shows the possibility of performing super large-scale analyses with GeoFEM and a parallel computer.
