In this study, to deal with complex moving boundary problems, we have extended s-version of finite element method (SFEM) to large-scale parallel analysis. The proposed method achieves both high accuracy and low computational cost by superimposing higher resolution arbitrary local meshes on structured coarser meshes based on interface capturing method which represents the entire domain. And we have improved the accuracy of integration by using B-spline functions as basis functions of the structured meshes. In addition, we apply a parallelization method based on overlapping domain decomposition to the proposed method and perform a strong scaling test to evaluate its performance.
