Multi-fidelity design space exploration

What is it about?

Engineers often omit complex simulations during design work because of their high computational cost. Instead, they sacrifice physical accuracy to run in a reasonable amount of time. We present a new method for design space exploration that alleviates this problem, use a 2D NACA airfoil for demonstration.

Why is it important?

Our method maps the entire design space in a physically-accurate way at 10-100x less cost. Rather than seeking a local optimum, our approach gives designers a better understanding of (a) trade-offs in performance objectives and (b) their sensitivity to design parameters. Furthermore, mapping the entire space allows designers to pivot at no additional cost when design objectives change mid-way through a project.
