一种提高现有有限元求解器速度的方法

Performance improving of existing equation solvers for finite element analysis with unrolling strategies

静力方程求解器是有限元分析程序的核心。随着求解规模的增大 ,求解器往往成为其工作的瓶颈。目前大量有限元程序采用的是一维变列高存储格式的直接法求解器 ,在这种求解器中引入循环展开 (loop- unrolling)技术以改进其工作性能。算例表明 ,求解速度得到很大提高。

Large scale equation solver is a key technique in finite element programs.It is often the bottleneck with respect to computer time and storage.The direct solver with skyline storage scheme is adopted by many current finite element programs.A method to incorporate the loop unrolling strategy to improve its efficiency is proposed.
