I'm trying to minimize the drag of the NACA 0012 airfoil. Please find the details in the attached image. It is a symmetric case with only the upper surface.

I'm trying the following constraints:

OPT_OBJECTIVE= DRAG

OPT_CONSTRAINT= ( AIRFOIL_THICKNESS > 0.6 ) * 1.0

But the results are wrong. I think the problem is with my constraints. Please help me fix this.
