Numerical analysis is effective for quantitative strength evaluation of composite materials such as CFRP. Simulations that distinguish between fibers and resins cannot be performed in a realistic amount of time. Therefore, multiscale simulators based on homogenization theory are employed. Simulations of hydrogen tanks are expected to require an enormous amount of computation time, even when using the homogenization method. In this study, parallel computation scheme is applied to reduce the computation time. When using multiple types of different microstructures, the conventional domain decomposition method for macroscopic structures may lead an unbalanced amount of computation. We evaluate to apply a static load balancing technique to parallel computation of an two-scale homogenization simulation.
