有限元求解器Calculix预处理并行优化方法
The Parallel Optimization of Preconditioning for the Finite Element Solution Calculix
摘要
Abstract
Aiming at the problems of large scale numerical computing and analysis in ship strength fatigue analysis,this paper presents an improved mechanism with optimized pretreatment of linear equation group iteration at open-source finite element solver Calculix in National Supercomputing Center in Guangzhou.It can resolve the multi-row double threshold incomplete decomposition based on column pivoting and the incomplete LU decomposition proves to proceed.Hence the prototype system has been developed in the center.And the practical experiments and testing results show that the computing time of ship strength fa-tigue analysis can be reduced effectively.关键词
