Hybrid CFD acceleration

Goal

Accelerate a conventional solver without losing residual checks, conservation, or fallback.

Candidate methods

INC, Solver-in-the-Loop, PICT, NeuroSEM, neural-operator preconditioned Newton, and geometry-aware neural preconditioners.

Experimental protocol

• compare against the unaccelerated solver and classical preconditioners;
• use matched-error wall-clock and iteration counts;
• test unseen meshes, timesteps, and solver settings;
• report accepted learned steps, rejected steps, fallback cost, residual reduction, and conservation defects;
• include long-rollout turbulence statistics for unsteady cases.
