The method of minimizing the communication quantity between the majorzone and the minor zoneof overset-grid CFD parallel computing are introduced.In orderto minimize the communication quantity without changing the computingresult,the majorgrid points are classified into three types based on the maze algorithm.Then the overset relationship graph is brought forward to control the com-munication order of multi-level overset grids problem.The experimental results show that the communication optimization method of overset-grid CFD parallel computing can get good parallel efficiency.
