Full-field prediction for engineering-scale three-dimensional aircraft with multigrid-hierarchical learning
Researchers introduce MHLF, a multigrid-hierarchical deep learning framework that accelerates computational fluid dynamics simulations for full-scale 3D aircraft by 3-8x while maintaining high-fidelity accuracy across subsonic, transonic, and supersonic flight regimes. This breakthrough addresses a critical bottleneck in aerospace design by enabling practical full-flow-field prediction for engineering-scale aircraft, moving beyond previous limitations of 2D or simplified models.
