What is it about?
Physics-assimilated neural networks (PANNs) are proposed and nonlinear mode decomposition are performed over a NACA 4412 airfoil, which is a good supplement to the POD and DMD analysis.

Why is it important?
Physics is assimilated into the latent space of the highly nonlinear dynamical system via a neural network and furthermore spatiotemporal decomposed modes are capable of reflecting the underlying dynamics.
