Why the optimization procedure went to the direction of the maximum value of Drag?
 

Hi all,

When I’m using SU2 to optimize a model made by myself, I want to get a minimum value of Drag. What I wrote in the configure file is:

OPT_OBJECTIVE= DRAG*0.1
OPT_CONSTRAINT= (LIFT < -0.5 )*0.1

And the Scale for the FFD_CONTROL_POINT that I set is 0.1

But the optimization procedure went to the direction of the maximum value of Drag :(

Have anyone met the same problem? Or Does anyone know how to solve it?

Thank you!
