摘要
有限元网格的区域划分是影响有限元并行计算效率的关键因素,介绍了几类有限元并行计算的图剖分方法,并在此基础上提出了一种改进的划分方法,经过验证这种方法是有效的,在负载均衡度相同的情况下,能有效地减少并行计算的通信量。
The domain decomposition of the mesh for Par-FEM calculation is a critical factor influencing the computing efficiency. Different types of graph partitioning methods were introduced herein, and an improved partitioning method was proposed. The case study shows that the improved method is effective and can reduce the communication eo.s.t of parallel computation on the condition of same load balance.
