Summary

Physics-Audited Agentic SciML (PA-SciML) introduces a verification-first workflow for discovering surrogate models in scientific machine learning, addressing the limitation where low error metrics do not guarantee physics compliance. This workflow fixes a scoring evaluator before search, derives machine-checkable physics requirements, and checks each trained candidate's outputs. It also searches prescribed input ranges for high-violation cases, reporting a surrogate as verified only under stated checks. Optionally, it adds advisory numerical probes and tests isolated modeling changes. In computational-solid-mechanics examples, PA-SciML selected models with lower validation error that passed linear-elastic and causality checks, unlike error-only baselines which failed stricter physics tests.

Key takeaway

For Machine Learning Engineers developing surrogate models in scientific machine learning, prioritize physics-audited verification over relying solely on error metrics. Your models must satisfy critical physics constraints like boundary conditions or causality, which error-only approaches often miss. Implement a verification-first workflow to ensure discovered models are robust and physically sound, especially in critical applications like computational solid mechanics.
