PHengLEI is a software platform of Computational Fluid Dynamics (CFD) developed by China Aerodynamics Research and Development Center (CARDC) with completely independent intellectual property rights. It has been widely used in China. As an important part of the national numerical wind tunnel system, PHengLEI are integrating the discipline physical models including helicopter rotor, aircraft icing, wind engineering, chemical reaction and combustion, virtual flight, high order method on both structured and unstructured grids. In order to meet the needs of integrated development of multi-disciplinary and multi-physical models and to adapt to the next generation of high-performance computer hardware, based on the existing work, the architecture and data structure of the next-generation PHengLEI software are further designed.
