Reproduce a suitable tutorial and validate the flow solution before enabling optimization. Define objective functions and constraints explicitly, then inspect whether proposed changes remain physically and geometrically meaningful. Keep mesh, solver settings, and convergence histories together, and check selected designs with additional verification rather than accepting an optimizer's final value uncritically.
This is best suited to researchers studying aerodynamic design and optimization. Before committing a larger project, account for these trade-offs: requires numerical simulation expertise; optimization results depend on model validity.
