SU Bo1,QIAN Ruo-jun2,YUAN Xing-fei3(1.Faculty of Science,Jiangsu University,Zhenjiang 212013,China;2.College of Civil Engineering,Tongji University,Shanghai 200092,China;3.College of Civil Engineering and Architecture,Zhejiang University,Hangzhou 310058,China)  
It is a key step to find a proper and effective data exchange approach for FSI analysis.The theory and method of data exchange on fluid-structure interaction is studied.The basic principle for data exchange is deduced including kinematics continuity condition,dynamics continuity condition and energy conservation.The data exchange methods can be classified into two main categories: local interpolation method and global interpolation method.Mapping point interpolation,weight residual method,Constant Volume Tetrahedron(CVT) are studied in local interpolation method.The search algorithm for host element and mapping point is also given.Splines method,Shepard method and radial based function(RBF) are studied in global interpolation method.The time interpolation modes between CSD、CFD for transient problems are also given.The paper can be a direction in theory and method of data exchange on coupling interface for FSI computation.
