- 通过多模态代理提取图文输入中的结构化建模信息。
- 自验证代码生成机制确保模拟结果物理有效且可执行。
- 适合希望自动化仿真流程的工程师或科研人员使用。
有限元分析(FEA)是现代工程设计的核心,但其流程复杂且高度依赖专业知识。尽管近期已有将大语言模型(LLM)引入FEA的研究,现有方法在处理多模态输入和执行复杂任务方面仍存在局限。为此,我们提出VFEAgent——一个端到端的多智能体系统,可直接从输入图像和问题描述中自动完成有限元建模与仿真。该方法包含两个核心组件:(1) 基于ReAct驱动推理的多模态视觉-语言多智能体管道,用于从异构输入中提取结构化的FEA规格;(2) 验证优先的代码生成框架,集成稳健的自调试与回退机制,确保代码可执行性与物理合理性。我们在多种工程力学场景下系统评估了该系统,结果显示VFEAgent在生成完整且物理有效的仿真方面成功率高,优于基于LLM的基线方法,在可靠性和正确性上表现更优。这些发现验证了自动化完整FEA工作流的可行性,凸显该框架解放工程师、减少手动分析负担的潜力。
原文摘要 · Abstract (English)
Finite Element Analysis (FEA) serves as the cornerstone of modern engineering design. However, its workflow is inherently complex and relies heavily on domain expertise. Although recent efforts have integrated Large Language Models (LLMs) into FEA, existing approaches face limitations in handling multimodal inputs and executing complex tasks. To address these limitations, we propose VFEAgent, an end-to-end multi-agent system designed to automate FEA modeling and simulation directly from input images and problem descriptions. Our methodology integrates two core components: (1) a multimodal vision-language multi-agent pipeline that employs ReAct-driven reasoning to extract structured FEA specifications from heterogeneous inputs and (2) a verification-first code synthesis framework, incorporating robust self-debugging and fallback mechanisms to ensure executability and physical validity. We systematically evaluated the system across various engineering mechanics scenarios. The results demonstrate that VFEAgent achieves a high success rate in generating complete and physically valid simulations, outperforming LLM-based baseline methods in reliability and correctness. These findings validate the feasibility of automating the complete FEA workflow, highlighting the framework's potential to liberate engineers from tedious manual analysis.
