三维有限元数值模拟的研究

Study on three-dimensional finite element numerical simulation

有限元方法是一种工程问题的近似解的数值方法.从有限元解的收敛条件,四面体单元的形函数和四面体有限元格式等方面着手结合三维有限元数值模拟的基本原理进行研究.

Finite element method is an approximate solution of engineering problems of numerical methods. In this paper, the convergence of finite element solution conditions, the shape function of tetrahedral units and tetrahedral finite element format, such as combining aspects of three-dimensional finite element numerical simulation of a series of basic principles of research. The three-dimensional finite element numerical simulation of reservoir used in the quantitative prediction of crack to get good results.
