Reply To: Fluent Adjoint Solver;constant chordline constraint

[Aras karimi]

Hi Dear Murari,

I followed your suggestion exactly and constraint the movement of the wing in x and z directions. I used the ’Radial Basis Function'  morphing method and considered the size of the adjoint box as its default.

After performing the optimization at the angle of attack 7 degrees using the gradient based optimizer, the optimizer stopped automatically and had optimized the geometry sixty times. According to the figure below, the final geometry has a very deformed TE, which is no longer a wing:

What should I do to solve this problem?  Are there any other settings I need to apply?

Is there any other way to fix the chord length during optimization?

I used the bounded-by-surface design condition and failed.

I will be really grateful if you help me. Thankyou

Regards.
