Source code for MetaOpenFOAM: LLM-assisted sensitivity analysis and optimization in CFD

This dataset provides the source code supporting the paper “Large Language Model-Assisted Sensitivity Analysis and Parameter Optimization in Computational Fluid Dynamics”, submitted to Theoretical and Applied Mechanics Letters.The repository contains the implementation of the OptMetaOpenFOAM framework, including the LLM-driven workflow orchestration, CFD simulation automation, post-processing, sensitivity analysis, and parameter optimization modules.All numerical results and figures reported in the paper can be reproduced by running the provided code with standard OpenFOAM tutorials or user-defined cases. Simulation data are not included, as they are generated deterministically through the executable workflow.
