摘要

在当前空气动力学研究中，各类求解计算程序缺乏与其配套的前后处理平台，容易降低研究人员的工作效率和软件的实用性。针对这一问题，NNW集成框架系统作为国家数值风洞项目（NNW）中数值模拟软件平台的重要组成部分，将前处理软件、求解计算程序、后处理软件集成于统一的集成环境，针对未来E级高性能计算的特点，以中间件为框架核心，按照一定的工作流模型集成多种功能模块，通过过程集成的方式，实现数据集成、计算集成、分析集成。同时，NNW集成框架系统支持对各类求解器的调度、作业管理、实时监控，为用户提供自动化多学科计算平台。通过在实际计算环境下运行计算案例，表明该集成框架系统能够为用户提供完整的计算工具链，快速定制一套或多套网格，并将与之配套的前处理和后处理计算结果可视化。

Abstract

In the current aerodynamic research

various solving calculation programs lack the pre- and post-processing platforms that are compatible with them. This shortage easily reduces the work efficiency of researchers and the practicability of software. In response to this problem

the NNW integrated framework system

as an important part of the numerical simulation software platform in the National Numerical Windtunnel Project (NNW)

integrates the pre-processing software

solving calculation program

and post-processing software into a unified integrated environment. The system considers the characteristics of high-performance computing with middleware as the core of the framework

integrates multiple functional modules according to a certain workflow model

and realizes data integration

calculation integration

and analysis integration through process integration. Moreover

the NNW integrated framework system supports scheduling

job management

and real-time monitoring of various solvers

providing users with an automated multi-disciplinary computing platform. By running the calculation case in an actual calculation environment

it is shown that the integrated framework system can provide users with a complete calculation tool chain

quickly customize one or more sets of grids and visualize the matching pre-processing and post-processing calculation results.
