Hi Rob,

I am studying the shape optimization of a 3D wing using Fluent's adjoint solver.My geometry is as shown below:

I have a design condition that the wing chord length must remain constant while optimizing.
I have checked the design conditions tab in the adjoint solver options and I have also tested the design conditions 'fixed-walls-constraint' and 'bounded-by-plane' but I did not succeed(maybe I did not set it correctly). I also thoroughly read the user manual of Fluent's adjoint solver. The following figure is the design conditions available in the adjoint solver:

I have wasted a lot of time trying to apply this design condition (More than six months) and have not succeeded. I hope you can help me.
