Keywords: flutter, aeroelasticity, non-stationary aerodynamics, vortex-lattice method

The influences of mesh refinement, wake parameters and integration interval on aeroelastic response simulations are investigated. The method uses finite element method for structural analysis, vortex-lattice method for non-stationary aerodynamics and surface spline interpolation for meshes coupling. Results are presented as computer effort versus results accuracy.
