Why consider it

Links simulation with optimization methods

Open source supports research development

What to keep in mind

Requires numerical simulation expertise

Optimization results depend on model validity

How to use it well

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.

A few things you might be wondering.

Is SU2 free?

The LGPL software is available without a license subscription and includes CFD simulation and Design optimization. This covers the downloadable application, while optional support, third-party services, and separately licensed materials have their own terms.

Does SU2 support design optimization?

Yes. Optimization and sensitivity analysis are central use cases.

Should optimization start before validating the simulation?

No. An invalid baseline model can produce misleading optimized designs.
