GeoPT: Scaling Physics Simulation via Lifted Geometric Pre-Training
Wu et al.
What it does
Pre-trains a neural simulator on over a million off-the-shelf geometries, lifted with synthetic dynamics so the self-supervision is about how flow and deformation behave, not shape alone.
Why it matters
Reports 20–60% fewer labelled simulations and 2× faster convergence on car, aircraft, ship and crash benchmarks: a way around the cost of simulation data.
