Accurate and effective data exchange is key to fluid structure interaction (FSI) analysis. This paper proposes a local dynamic data exchange method to perform the FSI analysis, which overcomes the difficulties of the surface fitting methods such as numerical instability due to ill-conditioned system matrix from the manifolds in curved geometries and requirement of a huge amount of CPU time in interpolating a large quantity of data. This approach also overcomes such difficulties of the surface tracking methods as numerical errors due to the roughness from ambiguity of normal directions around edges. In order to validate the method, a 3D cylinder, a near space propeller and a high altitude balloon are analyzed and the results compared with those of the constant volume tetrahedron (CVT) method, which demonstrates that the method is superior in numerical stability and surface smoothness, and is suitable for data exchange in FSI analysis.
