ANSYS 中的 等值参数 是什么意思?

SANYAN68

The ANSYS program's element library includes two basic types of area and volume elements: linear (with or without extra shapes), and quadratic. These basic element types are represented schematically in Figure 2.1. Let's examine some of the considerations involved in choosing between these two basic element types:
Basic area and volume types available in the ANSYS program

(a) Linear isoparametric
(b) Linear isoparametric with extra shapes
(c) Quadratic
----------------------------------------------------------------------------------------

(a)线性 等值参数

(b)有额外形状的线性 等值参数

(c)二次方


请教一下高手.....

等值参数 (isoparametric) 是什么意思?

简单来说，等参元就是就是采用等参变换的单元，即对单元几何形状和单元内的场函数采用相同数目的节点参数和相同的形函数进行变换而设计出的一种新单元。
如果想具体了解的话建议找一本有限元理论方面的书籍，任意一本都会比较详细介绍等参元方面的问题
