Accurate Aerodynamic Sensitivity Analysis Using Adjoint Equations

An accurate aerodynamic sensitivity analysis method for the adjoint approach is described. The present method uses the continuous adjoint approach to avoid excessive memory requirement, and the diagonalized alternating direction implicit (DADI) relaxation with multigrid acceleration is used for the...

Description
Summary:An accurate aerodynamic sensitivity analysis method for the adjoint approach is described. The present method uses the continuous adjoint approach to avoid excessive memory requirement, and the diagonalized alternating direction implicit (DADI) relaxation with multigrid acceleration is used for the fast convergence.
