Abstract:Successfully training physics-informed neural networks (PINNs) for highly nonlinear partial differential
equations (PDEs) on complex 3D domains remains a challenging task. In this paper, PINNs are employed to solve the 3D incompressible Navier-Stokes equations at moderate to high Reynolds numbers for complex geometries. The presented method utilizes very sparsely distributed solution
data in the domain. A detailed investigation of the effect of the amount of supplied data and the PDE-based
regularizers is pres… Show more
