基于SURPAC的ANSYS三维复杂模型的构建方法

摘要

对大型数值分析软件FLAC3D、ANSYS进行了对比，发现ANSYS在对不规则模型进行网格划分方面优于FLAC3D ，并针对FLAC3D、ANSYS在建立不规则复杂模型时存在耗时耗力等问题，提出了基于SURPAC的ANSYS复杂模型的构建方法：采用JAVA语言编写了SURPAC⁃ANSYS接口程序，将SURPAC模型的点线面数据转换成ANSYS识别的数据格式，从而实现SURPAC模型到ANSYS模型的构建。最后，通过新城金矿V＃矿体的工程实例，解决了SURPAC模型到ANSYS的转换以及模型难重构等问题。结果表明：此构建方法可行且高效。%After comparison of numerical analysis software FLAC3D with ANSYS, it was found that ANSYS is preferable than FLAC3D in mesh generation for an irregular model. As for the difficulty in the establishment of irregular and complex model with FLAC3D and SNSYS, it was proposed to build a complex model with ANSYS based on SURPAC model. With a SURPAC⁃ANSYS interface program in JAVA language, the data of points, lines and surfaces for the model in SURPAC were transferred into the data identified and used in the software ANSYS, resulting in a mode reconstruction in ANSYS. The orebody V# in Xincheng Gold Mine was taken as an example to testify such model construction method, verifying its effectiveness and feasibility.
