slashss4 New Member Join Date: Sep 2014 Posts: 8 Rep Power: 12	Hello again, I tried to optimize NACA65210 for supersonic conditions with C-Grid. I defined all constraints and geometrical parameters clearly. However, when I run continuous_adjoint.py I get the drag coefficient gradient is 0. How can I solve it ? Kind Regards,
