Your Simulation Runs but Solves the Wrong Physics: PDE-Grounded Intent Verification for LLM-Generated Multiphysics Simulation Code
Researchers present a method to verify that LLM-generated simulation code solves the intended physics equations, not just that it executes successfully. They introduce Intent Fidelity Score (IFS) to structurally compare generated PDEs against user intent, and demonstrate on 220 multiphysics cases that execution-only validation misses 39-40% of cases solving incorrect physics.
