The MetaOpenFOAM repository is an application that automates the setup and execution of OpenFOAM CFD simulations using a multi-agent system powered by Large Language Models (LLMs). It integrates the MetaGPT framework to define specialized agents (Architect, TaskDivide, InputWriter, Runner, Reviewer) that collaboratively interpret user requirements, generate OpenFOAM input files, run simulations, and review results. Additionally, it incorporates the active_subspaces library for parameter optimization and sensitivity analysis in the `OptMetaOpenfoam.py` workflow. The system processes OpenFOAM tutorials to build retrieval-augmented generation (RAG) vector databases, enabling the LLM agents to access relevant case information when generating simulation inputs. Configuration and path management are handled via a centralized YAML configuration, and the application relies on external dependencies including OpenFOAM-10, Conda, and LLM APIs (OpenAI or DeepSeek). While the project demonstrates a sophisticated integration of CFD simulation, LLM agents, and sensitivity analysis, it is marked as deprecated in favor of a successor tool (sim-cli).
