Hi, I am using SU2 6.2.0 for design optimization (CONTINUOUS_ADJOINT). I attached a result of the adjoint solver. The result is really weird. As the first 1000 iterations, from the result, I thought it converged. But it suddenly oscillated really bad, but finally, it will converge to a value which is really large.
By the way, the Direct simulation converged really well within 2000 iterations.
Does anyone know what happens here? Thanks
