以ANSYS为平台的复杂模型到FLAC^(3D)导入技术

Technology of complex model to FLAC^(3D) with ANSYS platform

为了克服使用FLAC3D软件难以建立复杂的模型,而且容易出错的缺点,提出了一种快速建模方法,该方法用ANSYS建立复杂的有限元模型、分配材料属性、划分网格,然后采用Visual C++语言编写的ANSYS_TO_FLAC3D接口程序把复杂模型导入FLAC3D,从而实现在FLAC3D里建立复杂模型的目的。此外,通过两个具体实例的三维建模导入检验了该方法的有效性和可行性。结果表明:以ANSYS为平台的复杂模型到FLAC3D导入的结果另人满意,该方法在FLAC3D的复杂模型建立方面具有一定的参考价值。

In order to overcome the difficulty in building the complicated model, and easily making mistakes when using the FLAC^3D, a fast building model method is put forward, which is used to build the complicated numerical model of FLAC^3D by using ANSYS and distributes material property, meshing. Then leading the complicated model into the FLAC^3D by using the interface program of ANSYS_TO_FLAC^3D is compile with Visual C＋＋ language, thereby achieving the purpose of building the complicated model in FLAC^3D.Besides,this FLAC^3D model gives an example with the advantages of different programs. Then three-dimensional numerical models example are developed and the case study shows that the validity and feasibility. The result shows that complex model to FLAC^3D with ANSYS platform is satisfactory. This method in building model of FLAC^3D has some references value.
