A dynamic-mode-decomposition-based acceleration method for unsteady adjoint equations at low Reynolds numbers
The computational cost of unsteady adjoint equations remains high in adjoint-based unsteady aerodynamic optimization. In this letter, the solution of unsteady adjoint equations is accelerated by dynamic mode decomposition (DMD). The pseudo-time marching of every real-time step is approximated as an...
