On the use of Runge-Kutta time-marching and multigrid for the solution of steady adjoint equations
This paper considers the solution of steady adjoint equations using a class of iterative methods which includes preconditioned Runge-Kutta time-marching with multigrid. It is shown that, if formulated correctly, equal numbers of iterations of the direct and adjoint iterative solvers will result in t...
