Title: Multiscale Physics-Informed Neural Network for Complex Fluid Flows with Long-Range Dependencies

Abstract:
arXiv:2604.05652v1 Announce Type: cross Abstract: Fluid flows are governed by the nonlinear Navier-Stokes equations, which can manifest multiscale dynamics even from predictable initial conditions. Predicting such phenomena remains a formidable challenge in scientific machine learning, particularly regarding convergence speed, data requirements, and solution accuracy. In complex fluid flows, these challenges are exacerbated by long-range spatial dependencies arising from distant boundary conditi
