Abstract: This paper analyzes the challenge of developing parallel numerical simulation software based on the programming framework, which is used for high-performance numerical simulation. Then, on the basis of this analysis, this paper designs and develops a graphical programming tool for parallel numerical simulation based on the JAUMIN (J adaptive unstructured mesh application infrastructure) framework. The graphical programming tool uses a programming scheme based on the structured flow chart, which can hide the programming interface of JAUMIN, and can help users without the experience of programming framework to develop parallel application software based on JAUMIN quickly. Results from practice application show that this tool can significantly improve the development efficiency of parallel application software and reduce the difficulty of programming. Meanwhile the code generated by the programming tool is standard and normal, which makes the software maintenance efficiency be enhanced.
