Hi everyone,

I am studying the shape optimization of a 3D wing using Fluent's adjoint solver.
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.
I have wasted a lot of time trying to apply this design condition (More than few months) and have not succeeded.

Can anyone help me how to apply this design condition?
Thankyou
