Researchers have developed M$^3$ (Multi-scale Morton Measure), a new framework designed to improve the training of neural surrogate models for physical simulations. This method addresses issues of uneven supervision and spatial inconsistencies by partitioning space based on physical variation and distributing supervision across multiple scales. When tested on large-scale industrial datasets, M$^3$ demonstrated significant improvements, achieving up to 4.7 times lower error in volumetric cases and outperforming models trained on higher-resolution data by reducing physics-weighted relative L2 error by 3-4 times.
