FLAC^(3D)前处理程序的开发及仿真效果检验

DEVELOPMENT OF PRE-PROCESSING PACKAGE FOR FLAC^(3D) AND VERIFICATION OF ITS SIMULATING EFFECTS

在FLAC3D软件提供的初始单元模型(primitive mesh)的基础上,采用Fortran语言编写了FLAC3D前处理程序,在工程实践中,实现更准确、快捷地建立复杂的FLAD3D计算模型;并探讨了其基本思路、计算方法以及该程序的突出特点;最后,以工程实例检验了此程序的处理功能和仿真效果。

FLAC3D (Fast Lagrangian Analysis of Continua in 3 Dimensions),developed by Itasca Consulting Group.Inc.,USA,is a widely used computational package in the world. Since FLAC3D is operated normally through commands,it takes considerable time to build complex computation models. The fundamental principles and characteristics of a pre-processing program for FLAC3D are discussed in detail based on the primitive meshes provided by FLAC3D. Meanwhile,in order to verify the program,an example of simulation procedures and results is given.
