The complicated shape region is divided into many sub-regions. A new method of inner-boundary wind-proof coupling between multiple regions is developed to realize the smooth transition of the solution of adjacent sub-regions and the multi-region coupling to obtain the numerical value of the overall flow field solution. The numerical calculation of the two-dimensional airfoil transonic flow and the circular supersonic supersonic flow are carried out. The calculated results are compared with the single-zone calculation results and the experimental results. Parallel partitioning is introduced into the “first in, first out” synchronization control waiting mechanism to achieve high efficiency parallel computing, but also analyzes the main factors that affect the parallel efficiency.
