Hey all,

I'm facing a tough problem when I was trying to optimize ONERA M6 3D wing using the mesh file with FFD Box information, it always diverged in the second step

Before when I tried to optimize the same model with the mesh file with FFD Box information (ONERAM6_inv_FFD.su2, which was offered on the official website), the optimization process went smoothly. This time, however, when I used "DEF_SU2" operation to add FFD information in the ONERAM6_inv_FFD.su2 mesh file myself (I put the same FFD information as the tutorial in the configuration file), the optimization process always diverged in the second step (DSN_002).

I'm very disturbed about this problem these days Does anyone face the same problem? Or can anyone give me some advice about it? Any hint will be helpful!

Thank you!
