摘要
Fluent软件是目前国际上比较流行的通用CFD软件包,用于模拟从不可压缩到高度可压缩范围内的复杂流动,对大规模问题可用并行多重网格方法进行求解.为了找出Fluent软件的最佳解题规模和并行粒度,以期最大限度地发挥软件和硬件的效能,对Fluent软件采用的多重网格并行算法进行了理论分析,通过实验,重点讨论了在并行求解过程中,不同的多重网格循环方法、区域分裂方法、解题的规模和计算节点数对并行性能的影响.结果证明,Fluent软件采用V循环的并行性能最好,HPCC还有很大的升级空间.
Fluent is a popular CFD software package now, it can model complicated fluxion question from incondensability to the highly condensability. It can use parallel multi-grid method to solve the largescale problems. In order to find out the suitable scale and parallel granularity of the Fluent software while it makes the solution, and make the best of the software and the hardware, it analyses the multi-grid method and domain decomposition method of the FLUENT software and tests again and again. It mainly discusses the influence of the different multi-grid cycle method, domain decomposition method, the scale of sample and the number of computing nodes on parallel efficiency. The results from the theories analysis and the experiments show that the Fluent software has favorable parallel performance and the PEM Fuel Cell Model and HPCC could have better performance by upgraded well.
