Hi all,

My discrete adjoint solver does not converge well. After thousands of iterations, it still oscillates, and the residuals are about 1e-3. It is different from the direct solver where there are many control variables, so I am wondering how to control its convergence somehow.

Thanks!

Well, after setting the right obj func, the derivative during iteration is reasonable, and it takes about 2e4 iterations to get converged.
