Hi all,

When Iím 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!
