U-Nets and FNOs compared for multi-scale PDE surrogates
Paper title Towards Multi-spatiotemporal-scale Generalized PDE Modeling
Paper arXiv 2209.15616PDF
Compares ResNet, FNO and U-Net surrogates on 2D fluid problems, brings modern U-Net designs from image generation to PDEs, mixes FNO blocks into U-Nets, and conditions one model on PDE parameters and time step.
