工程中复杂力学问题的数值模拟与计算是先进制造技术和虚拟现实技术的重要组成部分,相应的建模与高精度方法成为该方向的技术关键,对其地位及国内外发展现状进行了评述,指出了新型高精度单元建模的思路和涉及的关键问题。

Numerical simulating and high-accuracy computing of complex engineering problem are playing an important role in the advanced manufacture technology and the virtual reality. Therefore the modeling and high-accuracy computing will become a focus. From the point of element modeling, the paper aims to review the state of the art in these aspects. The contents cover the h-version, r-version, p-version, combined h-p version, combined r-p version, and error estimating . Also the strategy and procedure of the high-accuracy numerical analysis and the adaptive methods are discussed. The related ideas and key aspects to develop new element modeling with high-accuracy are pointed.
