Development of communication mechanism for the fully coupled multiscale model of 3D compression test

Abstract

Abstract The implementation of a dedicated communication mechanism between micro- and macroscale models of the fully coupled multiscale numerical approach is the topic of the paper. The presented solution is based on the System V IPC message queue that is part of modern Linux-based operating systems. Developed and implemented approach is validated with a selected case study of a 3D compression test with the microscale model based on an implicit Johnson–Cook model, which is solved as a separate external process. The communication mechanism can be the basis of the efficient fully coupled FE2 model.
