Problem the AI is intended to solve

We are investigating the use of Graph Convolutional Neural Networks to learn relationship between airfoil coordinates and predict the performance for aerodynamics analysis. Inputs include the shape of the airfoil and outputs are the coefficient of lift, drag, and moment.

Expected benefits

The impact is we have a new type of neural network architecture that we can potentially use for other projects.
