基于MATLAB与ANSYS的三维地质建模技术

The technology of building 3D geological model based on MATLAB and ANSYS

在数值仿真计算中,三维模型的建立是整个计算过程的基础,特别是对于复杂的地形地貌,建模难度较大。本文首先提取出等高线中点的三维坐标,利用MATLAB的插值函数,绘制出地表的三维网格图,并将其导入到ANSYS中,建立相应的三维计算模型。为三维地质建模提供了一个简单有效的方法。

Building 3D- model is the base of numerical analysis,and it is difficult to describe complex topography.Firsdy,this paper extracts 3D coordinates of the contour’s point and draws 3D grid map on the earth’s surface by using MATLAB interpolation function.Secondly,the map is imported into ANSYS and the 3D numerical model is established accordingly.The method on building 3D geological model is simple and effective.
