| 摘 要： | 为了扩大边界元多域分析的计算规模,对边界元子域并行算法进行了研究,针对不同的使用情况研制了不同的算法。算法引入分块技术以解决内存不足的矛盾,引入选主元或局部选主元技术以提高数值稳定性。特别是发展了多机一域算法,可以灵活解决不均匀子域划分的负载平衡问题。数值试验结果和实际工程应用都表明算法是有效的。

| Abstract: | To enlarge the computing scale of boundary element multi-region analysis,the boundary element sub-region parallel algorithms are investigated,and each algorithm is employed for the individual situation.The block technique is introduced to solve the lack of core problem,and the pivot technique to improve the numerical robustness.Especially,the multi-region one processor algorithm enables to flexibly solve the problem of load imbalance of nonuniform region division.The numericl tests and engineering application show the effectiveness of the algorithms. |
