Application Study of Parallel Algorithm for Meshless Method in CFD
Abstract:In this paper, parallel algorithm for three-dimensional meshless method proposed by Batina was studied detailedly. According to the calculation characteristics of meshless method in CFD,we mostly discussed parallel searching of satellite points in the Pre-processing stage and parallel algorithm in the stage of the main calculation, and gave the program flow chart of parallel algorithm for meshless method in the application of CFD and authentication example. We got the speedup and parallel efficiency of parallel algorithm, the results showed that meshless method has a unique parallelism and parallel efficiency.
Keywords: meshless method parallel algorithm parallel efficient CFD
