Abstract:

In order to impove the parallel efficiency in the CFD software,the RANS equation and Menter's kOmega SST twoequation model,a multigrid technology and the general data transfer method,a region of the load balancing method will be used.The software has passed the test on the Galaxy of Stars system,which was in the Research Center of Supercomputing Application of NUDT.More than 2048 CPUs were used to computing the wing/body configuration with 100 million cells,and the parallel efficiency has  achieved 48%.So this research improves the efficiency in the massively parallel computation of accurate force coefficients,and benefits to the massively parallel computation applications in engineering.

Key words: structured grid;massively parallel;load balance;numerical simulation
