Hello Ansys community,

I am going to optimize a 3D airfoil using Fluent's adjoint solver.I have two design constraints which are:

1-Fixed chord length

2-Fixed camber line

During optimization, these two conditions must be applied.I see a number of design conditions in the Design Tool, but I don't know which one I should use correctly.

I wasted a lot of time (more than six months) and failed to apply these two design constraints to the geometry.

I hope there is someone around the world who can help me. I am very disappointed.

Regards.

Getting answers in general is really disappointing. I have checked all the design conditions available in the adjoint solver such as 'fixed-walls-constraint' and 'bonded-by-plane' , but to no avail. I expected the experts from the Ansys community to help me solve this issue.

How to create a design condition is important so I haven't found any document or person in the world that can help me.

Can you describe the steps to do it in detail for me?  Thankyou
