本文对ADINA的前后处理进行二次开发,采用FORTRAN语言编写了一套ADINA非线性有限元软件的前后处理系统接口的软件包,其主要功能是采用非结构网格技术,建立能真实反映地球特性(包括断层的坐标、走向、以及断层的倾角、断层深度,以及地形和岩性等数据)的三维地球动力学模型;通过后处理接口程序,能进行三维问题的库伦破裂应力分析;同时我们研制了一套打分程序,能定量的判断计算和观测的GPS数据和最大主压应力的相符程度。此ADINA前后处理的二次开发,大大的提高ADINA的使用效率和进行地球动力学数值实验的效率,具有很大的必要性和现实意义。
In this paper, we develop the interface of ADINA nonlinear finite element software packages by using FORTRAN language, its main function is using unstructured grid technology to establish three dimensional geodynamic model which can reflect the real features of the earth structure (including the fault coordinates, direction, and fault dip, fault depth, and topography, and lithology data); by post-processing interfaces, we can analyze the three-dimensional problem of Coulomb failure stress; at the same time, we developed a scoring procedure to judge consistent of the calculated and observed data including GPS data and the largest principle compressive stress. This secondary development greatly improve the numerical simulating efficiency, especially for the geodynamic problems. It has great practical significance and necessity.
