MUSA-PINN: Multi-scale Weak-form Physics-Informed Neural Networks for Fluid Flow in Complex Geometries

Weizheng Zhang, Xunjie Xie, Hao Pan +4

The paper introduces MUSA-PINN, a multi-scale weak-form physics-informed neural network that enforces integral conservation laws over hierarchical spherical control volumes to impr…
