High order scheme zone divided parallel algorithm study in CFD

HOU Zhong xi WANG Zheng hua WANG Cheng yao (National University of Defense Technology, Changsha , 410073, China)  
Combined high order WENO scheme with zone divided parallel method, the high order zone divided parallel computation was realized on COWs and MPP systems based on MPI platform. High order scheme has good characters including high order at continuous zone and high resolution at discontinuous zone, but also bring more cost of calculation. Zone divided method can efficiently divide the CFD problem into sub problems which can interactively and paralleled execute. It can accelerate speed of calculation. Through the typical computation, it can be found that this algorithm not only maintain the advantages of high order scheme, but also decrease the wall time of program running.
