The fluid-structre interaction problems is important not only for the mechanical engineering problems like a flutter of an airfoil but also for the bioengineering problems like the blood flow in a blood vessel. For the flow analysis at the high Reynolds number of these problems, the method, the object can move freely in the fixed grid, highly affects the precision of the fluid analysis and elastic analysis by having the low resolution of the boundary layer. Therefore, we propose the boundary fitted fluid-structure interaction method and apply to analyze the flow around an oscillating elastic foil. As a result, it is possible to obtain the stable solution of the fluid analysis and elastic analysis. And It is clear about the characteristics of the unsteady fluid dynamics for the flow around the oscillating elastic foil.
