For high accuracy and stability of fluid-structure coupled analysis, each analysis method, namely fluid analysis and structure analysis, must have high accuracy and stability. Moreover their coupled algorithm should also be thoroughly examined. In the present group, the primary method is the coupling with SUPG / PSPG stabilized finite element method for fluid and Enriched Free Mesh Method for structure analysis while the particle method has also been developed as an alternative. Through practical applications, the presently developed methods will be examined and be extended to large-scale problems along with Large-Scale Parallel Computing group.
