摘要
本文认为所谓高性能有限元方法是一种特殊的低价位移算法 ,在理论和计算方面 ,它有以下优势 :1 )近似满足原数学 ,物理模型的全部特性 ;2 )它可以有效地满足工程中数值模拟的需要 ,具有粗网格高精度 ,对网格畸变敏感度低 ,不发生 Locking不收敛现象。基于以上两点看法 。
The paper holds that the so called finite element method of high performance is a particular lower order displacement scheme that offers the following theoretical and computational advantages:1/Preserving all mathematical and physical characteristics of the original problem;2/As a result,it is robust and efficient for the applications to numerical simulations based on engineering.By this standpoint,two kinds of locking free methods,developing in computational structure mechanics and CFD,are reviewed in the paper.
