Meshes are the input for computational fluid dynamics (CFD) analysis, whose size and quality have important impact on the simulation results. With the continuous advancement of high-fidelity CFD simulation, the scale of needed computational meshes has become larger and larger, which poses great challenges to the development of interactive mesh generation software. To address this issue, a parallel and distributed framework called PadMesh is proposed, which performs as the infrastructure for developing various interactive mesh generation software (e.g., structured, unstructured and Cartesian). First, the framework PadMesh is demonstrated, including the introduction of design principles, software architecture and key components, namely message-oriented middleware, client application, server application and parallel supporting module. Second, a parallel and distributed structured mesh generation software called PGridStar is developed based on PadMesh. Strategies are investigated on managing the visual data and distributed data for structured meshes. Finally, two functionalities of the preliminary PGridStar are presented, which validate the usability of PadMesh in developing interactive mesh generation software.

PadMesh：交互式网格生成软件的并行分布式框架

网格是计算流体动力学 (CFD) 分析的输入，其大小和质量对模拟结果有重要影响。随着高保真CFD仿真的不断进步，所需计算网格的规模越来越大，这对交互式网格生成软件的开发提出了很大的挑战。为了解决这个问题，提出了一种称为 PadMesh 的并行分布式框架，它作为开发各种交互式网格生成软件（例如，结构化、非结构化和笛卡尔）的基础设施。首先展示了PadMesh的框架，包括设计原理、软件架构和关键组件的介绍，即面向消息的中间件、客户端应用程序、服务器应用程序和并行支持模块。第二，基于PadMesh开发了并行分布式结构化网格生成软件PGridStar。研究了管理结构化网格的可视化数据和分布式数据的策略。最后，介绍了初步 PGridStar 的两个功能，它们验证了 PadMesh 在开发交互式网格生成软件中的可用性。
