Abstract

The implementation of multiscale numerical simulations on heterogeneous hardware architectures is presented in the paper. The simulations are composed of coupled micro and macro scale approaches, which are implemented by using cellular automata and finite element method respectively. Details of both of these methods are described in the papers as well. The simulations were performed for the problem of material heat treatment (macro scale) with simultaneous application of grain growth calculation (micro scale). Comparison of quantitative results obtained by using separated and coupled computing methods are presented in form of speedup and efficiency coefficients.
