|Abstract:||The authors developed an approximate-boundary-condition method for time-domain aeroelastic simulations on stationary body-conforming grids (AIAA 2004-0885). This method is extended to three dimensions in this paper. The CFD solver with the approx- imate boundary conditions is coupled with elastic equations to predict the aeroelastic properties of wings. The accurate nonlinear Euler equations are solved in the -eld, while the movement of the solid surfaces is accounted for in the approximate boundary condi- tions without moving or deforming the computational grids. The -rst-order approximate wall-boundary conditions are used in solving the full Euler equations. Results are com- pared with Euler solutions with the full boundary conditions on moving grids and known experimental data. © 2004 by the authors.
