Abstract

Today the numerical simulation of damage effects in heterogeneous materials is done by adaption of multiscale approaches. A consistent modeling in three dimensions with a high discretization resolution on each scale based on a hierarchical or concurrent multiscale model still has issues. The algorithms have to be optimized in regards to the computational efficiency and the distribution among available hardware resources often based on parallel hardware architectures. In the last 5 years high performance computing (HPC) as well as GPU computation techniques were established for investigation of scientific aims. Consequently, in this work substructuring methods for partitioning of FE meshed specimens were implemented, tested and adapted to the HPC computing framework using several hundred CPU nodes. An memory-efficient iterative and parallelized equation solver combined with a special preconditioning technique for solving the underlying equation system was modified and adapted to the consideration of combined CPU and GPU based computations.
