摘要

分析了船舶设计领域中基于有限元求解的大规模数值计算问题.在广州超算中心先导系统基础资源环境下对开源有限元求解器Calculix进行基于消息传递接口的并行化改造和移植.在兼容商业有限元分析软件前后处理文件格式的条件下，计算部分在超级计算机上采用多工况多结点并行计算完成.基于C/S模式搭建了船舶疲劳强度分析并行计算系统，实际算例和测试结果表明，同等条件下该Calculix并行化改造方法大大降低了船舶设计中数值分析部分的时间开销.

Abstract

This paper analyzes the status of open source finite element solver and commercial finite element solver. Aiming at the problem of large scale numerical computing and analysis in ship design field

a parallel transforming and transplanting mechanism of Calculix based on message passing interface (MPI) is proposed. Combined with high-performance computing capabilities of supercomputer

an efficient and rapid technological solution is found. On the condition of matching the pre and post processing files analyzed by other commercial finite element software

computational analysis uses the method of multi-state and multi-node parallel computation on supercomputer. Hence a ship fatigue strength parallel computation analysis platform is established

and the practical testing examples and results show that the parallel mechanism greatly reduces the computation time.
