Manifold Learning for Aerodynamic Shape Design Optimization
Problem
The high computational cost of iterative CFD-based aerodynamic shape design under modern complex design requirements.
Why it matters
Excessive CFD computation time and cost constrains aircraft design cycles and integrated design workflows.
What the AI did
A reduced-order model framework (LLE+COGA) with an active manifold auto-en/decoder compressed the large design space, and fast mesh deformation cut the cost of applying geometry changes to fine CFD meshes.
