AI surrogate models replacing traditional simulation workflows
#1NVIDIA Modulus, PhysicsX, and academic groups (Caltech, MIT) are producing neural operator models (Fourier Neural Operators, DeepONet) that learn PDE solutions and generalize across geometries. These surrogate models are moving from research demos to production deployment — Rolls-Royce, Airbus, and Boeing have all disclosed ML-accelerated simulation programs. Inference times of milliseconds vs. hours for CFD are now demonstrated on production-relevant geometries.
