Required packages

Dataset

Our airfoil designs are optimized airfoils in SU2. The original airfoils are generated by BezierGAN. BezierGAN was trained on UIUC airfoil coordinates database.

CFD solver and airfoil optimization

We use SU2 as the CFD solver to evaluate the performance of the airfoil design.

Usage

Train/evaluate Conditional-Bézier-GAN
