inverse isoparametric mapping

基本解釋

There is no explicit formulation of inverse mapping about the isoparametric element, so inverse mapping is avoided in finite element analysis.

Geometric dichotomy method is innovated and used for inverse isoparametric mapping in linear finite element, of which a property is proved and served as the foundation.
在證明線性等參單元的一個幾何特性的基礎上，提出了線性等參單元逆變換的幾何二分法。
The displacement boundary values of the small model use the results of the large model, which are obtained by interpolating with numerical inverse isoparametric mapping.
