摘要：
In this study, a parallel framework for the multiscale analysis of three-dimensional lattice structures is developed. The established parallel framework performs the multiscale analysis using the extended multiscale finite element method (EMsFEM) in a parallel environment provided by the portable and extensible toolkit for scientific computation (PETSc), which is a high-performance parallel scientific computing library. To realize this aim, we developed several modifications of the original EMsFEM method and adopted some routines from PETSc. Through numerical examples, the efficiency and accuracy of the proposed parallel computing framework were verified first. Then, the parallel acceleration ratio and parallel efficiency of the proposed parallel framework were studied. The proposed parallel computing framework shows good efficiency and can be used to deal with the analysis of large-scale lattice structures.
