基于AutoCAD与ANSYS建立双曲拱坝三维计算模型方法分析

Three-dimensional Calculation Method Research of the Establishment of Vaulted Dam Based on AutoCAD and ANSYS Software

选择AutoCAD软件作为双曲拱坝的三维处理平台,以图形交换文件SAT和DXF为基础,采用FORTRAN或Visual C++高级语言来读取、分析、处理数据文件,可以快速形成包括上、下游面结点坐标,溢流堰、分层廊道和基岩等的三维实体模型数据文件。将其通过ANSYS高级接口导入,对模型进行局部的修改和调整,便快速、准确地完成了复杂双曲拱坝三维模型的建立,提高了拱坝数值分析中建模的效率。

Choosing AutoCAD software as vaulted dam＇ s 3d processing platform, taking graphic exchange doeuments SAT and DXF as a base, using FORTRAN or Visual C ＋ ＋ high-level language to read, analyze, and process data files can rapidly form the three-dimensional entity model including the upstream and downstream side face node overflow weir, coordinate, corridor and rock. After getting vaulted dam analysis from data files and importing the Data files into ANSYS, to partly modify and adjust the model, the complex vaulted dam model uas quickly and accurately built and so as to enhance the efficiency of numerical analysis of the arch in model building.
