Hi,
I am running a wavy wall using SU2. The direct simulation converges ok, but when running the continuous adjoint, the linear solver diverges before the first iteration. When I set the LINEAR_SOLVER = FGMRES, the orthogonalization fails and the linear solver diverges. Changing LINEAR_SOLVER = BCGSTAB the problem was not solved. I am attaching the .cfg file (txt) and the prints with each linear solver option. Regards, Pedro. |
