摘要/Abstract

摘要：

多物理场耦合分析是复杂工程产品设计与优化的重要工具，但在实际应用中，CAE软件与算法的增量替换面临诸多困难，如商业软件封闭性强、开源软件功能单一和自主开发算法集成复杂等。为解决这些问题，通过深入研究多物理场耦合方案，并基于增量集成式架构、非结构网格映射算法的松耦合方案，依托开源及自研CAE软件开发了全自动增量替换式的多物理场耦合平台。平台采用模块化设计，支持CPU/GPU异构并行计算，通过数据(Field)、模块(Module)、节点(Node)和场景图(SceneGraph)的多层次框架，实现了仿真流程的灵活管理与定制，基于插件系统实现了自定义算法快速集成。通过平台实现了流固耦合分析计算中数据传递算法、流体分析软件和结构分析软件的拓展开发，证明了该平台在多物理场分析的增量替换上具有更加简便的优势，可以满足实际工程仿真需求。

Abstract:

Multiphysics-field coupling analysis is an important tool for the design and optimization of complex engineering products. However, in practical applications, the incremental replacement of CAE software and algorithms faces many difficulties, such as the strong closed nature of commercial software, the limited functionality of open-source software, and the complexity of integrating self-developed algorithms. To address these problems, through in-depth research on the multi-physics coupling scheme and based on a loosely coupled scheme of the incremental integration architecture and an unstructured grid mapping algorithm, a fully automatic incremental replacement multi-physics coupling platform was developed relying on open-source and self-developed CAE software. The platform adopted a modular design and supported heterogeneous parallel computing of CPU/GPU. A multi-level framework of Field (data), Module, Node, and SceneGraph enabled flexible management and customization of the simulation process. Based on the plug-in system, it realized the rapid integration of custom algorithms. By implementing the extended development of data transfer algorithms, fluid analysis software, and structural analysis software in fluid-structure coupling analysis and computation on the platform, it was demonstrated that this platform possessed a more convenient advantage in the incremental replacement of multi-physics field analysis and could meet the actual engineering simulation requirements.

Key words: multi-physics field simulation, coupled solution algorithms, incremental replacement, open source software, software integration
