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.
