Abstract
In this research, we develop a common fundamental aerodynamic analysis tool by extending FaSTAR-code to be able to handle fluid-structure interaction problems aimed for establishing the technical basis which accelerate the development of civil airplanes.

Reasons for using JSS2
JSS is necessary to complete numerical simulations of unsteady phenomenon and understand it in short time span .
Achievements of the Year
For the bechmarking of our aeroelastic analysis code, we computed flutter boundaries on AGARD wing (Fig.1). The computed flutter boundaries (Fig.2) are close to the experimental data and NASA's FUN3D results.
