Outline of Final Research Achievements

We have developed three-dimensional computational procedure using massively parallel computer for voxel finite element method. The results are followings;
1) Development of MPI/Open-MP hybrid type library for parallel computing and also for GPU. 2) Numerical integration scheme of only three integration points per dimension for representing arbitrary shapes within voxel FEM framework. 3) Development of nonlinear computation for magneto-restrictive materials with voxel-based nodal-edge finite element.
