Abstract

An AI system for computational fluid dynamics autonomously discovers physics corrections through vision-language verification and domain-specific code modification, outperforming general AI scientists in validity checking and scientific claim generation.

AI-generated summary

Recent LLM-based agents have closed substantial portions of the scientific discovery loop in software-only machine-learning research, in chemistry, and in biology. Extending the same loop to high-fidelity physical simulators is harder, because solver completion does not imply physical validity and many failure modes appear only in field-level imagery rather than in solver logs. We present AI CFD Scientist, an open-source AI scientist for computational fluid dynamics (CFD) that, to our knowledge, is the first to span literature-grounded ideation, validated execution, vision-based physics verification, source-code modification, and figure-grounded writing within a single inspectable workflow. Three coupled pathways cover parameter sweeps within a fixed solver, case-local C++ library compilation for new physical models, and open-ended hypothesis search against a reference comparator, all running on OpenFOAM through Foam-Agent. At the center of the framework is a vision-language physics-verification gate that inspects rendered flow fields before any result is accepted, rerun, or written into a manuscript. On five tasks under a shared GPT-5.5 backbone, AI CFD Scientist autonomously discovers a Spalart-Allmaras runtime correction that reduces lower-wall Cf RMSE against DNS by 7.89% on the periodic hill at Reh=5600; under matched LLM cost, two strong general AI-scientist baselines (ARIS, DeepScientist) execute partial CFD workflows but lack the domain-specific validity gates needed to convert runs into defensible scientific claims; and a controlled planted-failure ablation shows that the vision-language gate detects 14 of 16 silent failures missed by solver-level checks.

AICFDScientist is an open-source multi-agent framework for end-to-end CFD discovery built on OpenFOAM. The system combines literature-aware ideation, validated simulation setup generation, automated execution, mesh-independence checking, simulator source-code modification, VLM-based physics verification, reference-data alignment, and figure-grounded manuscript writing within a unified workflow.

The framework supports three pathways:

  1. Regular CFD experimentation and parameter sweeps
  2. Simulator source-code modification for custom physical models
  3. Open-ended discovery loops for iterative model exploration
