OnlyDense: Reduced-Order Modeling for Lagrangian simulation
Researchers introduce OnlyDense, a machine learning framework that reduces computational costs for Lagrangian particle simulation methods like SPH and MPM by representing massive particle systems as functions in Hilbert space rather than discrete particle sets. The method achieves 0.99+ R² accuracy using just 32 basis functions on million-particle simulations, combining classical reduced-order modeling with deep learning.
