摘要
探讨有限元求解器Calculix在广州超级计算中心TH-1-GZ先导系统环境下的实现原理,提出适用于TH-1-GZ先导系统高性能计算环境的Calculix并行化分析实现方案。针对船舶设计过程中船体疲劳强度分析计算的实际需要,建立船舶疲劳强度分析与数字化水池示范应用平台。对船体构件疲劳强度的分析测试结果充分表明:Calculix并行化分析可极大提高计算速度,有效提升工作效率。平台通过Web方式对外提供免费服务、接口简单、使用方便,实践证明该平台为船舶设计人员使用Calculix提供了一种新的有效方法。
In this paper we discuss the realisation principle of the finite element solver Calculix in Guangzhou Supercomputing Centre＇s TH-1-GZ pilot system environment, and propose the implementation scheme of parallelised analysis of Calculix suitable for the high-perform- ance computing environment of TH-I-GZ pilot system. Focused on the actual needs of hull fatigue strength analysis and calculation in the process of ship design, we establish a ships fatigue strength analysis and digitising pool demonstration application platform. It is fully demon- strated by the results of analytical test on the fatigue strength of hu｜l components that the Calculix parallelisation analysis can greatly improve the computing speed and effectively raise the operation efficiency. The application platform offers free services through the WEB interface, which is simple and easy to use. Practice has proved that the platform provides a new effective way for ship designers in using Calculix.
