Core Innovation: Scale-PINN
Scale-PINN introduces a novel learning strategy that integrates the iterative residual-correction principle, a cornerstone of numerical solvers, directly into the loss formulation of Physics-Informed Neural Networks (PINNs). This paradigm shift enhances both the speed and accuracy of PINN models, making them more practical for real-world scientific and engineering problems across diverse physics domains.
Algorithmic Fusion: Bridging ML & Numerical Methods
The core of Scale-PINN lies in its sequential correction algorithm, which modifies the standard PDE loss term Lpde by introducing an auxiliary sequence F. This term, mathematically derived from iterative schemes like modified Richardson iteration, uses a residual smoothing operator (e.g., Pa = (I - a^2 * grad^2)) to stabilize training. This fusion of numerical method rigor with deep learning flexibility allows for enhanced stability and faster convergence when integrated with standard optimizers like SGD and Adam.
Benchmarking Breakthroughs
Scale-PINN sets new benchmarks in computational efficiency and accuracy. For the challenging lid-driven cavity flow (Re=3200), it achieves a relative error of less than 2e-2 in sub-2 minutes, compared to 15 hours for prior state-of-the-art PINNs. It demonstrates robust performance from Re=400 to Re=20k, maintaining high accuracy and training times under 7 minutes. Beyond benchmarks, Scale-PINN successfully simulates complex aerodynamic flows (NACA0012 airfoils) and multiphysics transient dynamics (Rayleigh-Bénard convection) in minutes, validating its practical applicability.

Performance at High Reynolds Numbers
Scale-PINN excels in challenging fluid dynamics, accurately simulating flows up to Re=20,000. For these complex, high-stiffness problems where traditional PINNs often fail or take hours, Scale-PINN consistently achieves a relative error of 4.4e-2 with training times under 7 minutes. This demonstrates its capability for practical, high-fidelity simulations in demanding engineering scenarios.
