摘要
Massive parallel computational fluid dynamics is a vital tool for the modern aviation industry. The parallel aerodynamics numerical simulation software based on unstructured mixed grid and cell-centered finite volume method (FVM) was presented in this paper, which was developed for the complicated configurations of industrial grade. The algorithms for parallel implementation with message passing interface (MPI), including compact numerical discrete schemes, grid partition method for multiprocessors and data transfer scheme, are discussed in detail. The validity of parallel computing is verified using a revolving model of relatively small grid. Then a large transport airplane configuration with hundred millions of grid elements is used for parallel testing, and the efficiency is preserved above 80% up to 18816 processors.
