Domain Decomposition Based Parallel Fluid Analysis Using B-spline S-Version of Finite Element Method

Abstract

We aim to analyze a flapping-wing motion of a free-flight insect and have developed a new framework of s-version of finite element method (SFEM) called B-spline SFEM (BSFEM), which achieves both localized high accuracy and low computational cost. To analyze a large-scale problem such as a flapping free flight, distributed memory parallel computers are often used. In this study, we achieve parallel computing using BSFEM based on the graph structure representing the interactions between computational nodes. A strong scaling test is performed to evaluate its parallel performance.
