ML flow initialisation

Using a surrogate to start a transient CFD run

Paper title Accelerating Transient CFD through Machine Learning-Based Flow Initialization

Sharpe et al. (NVIDIA) · Aero & CFD

Paper arXiv 2503.15766PDF

Uses a DoMINO prediction as the initial field of an unsteady CFD run instead of uniform or potential flow: inside the region where the surrogate is trustworthy its field is used, and outside it is blended with uniform flow or a potential-flow solution. The solver itself is unchanged.
