I’ve been using this approach a lot lately, though in race car suspension, not aircraft! My strong advice is to start with clear objectives, the primary goal is weight, but recognize the secondary ones too. You clearly need a part that can perform and endure. I’d guess this type of part needs an extended service life. Prioritize constraints – if strength is critical, prioritize stiffness or minimize displacement.
         

Your constraints are what defines the usefulness of the process, it’s easy to do a GIGO on this (garbage in, garbage out). Iterate to improve.

Try to define some realistic load cases – aerodynamic forces from the aileron, actuator load, and moments from both. You might set these as point loads to start, keeping it simple. Later on, some might be better as pressure distributions.

You can evaluate the edge scenarios using boundary conditions. This simulates how the mounting and how your actuator interacts with the surrounding elements. You can impose fixed points at the areas where the actuator connects to other parts. These impose constraints on the design algorithm, so they get optimized for material usage.

Also, set your manufacturability constraints early on. If you plan to use 3D printing, you can set up constraints that limit overhang angles to reduce supports. It’ll look different if you’re using CNC. Then you need to specify tool accessibility and allowable undercuts.
