基于Gocad-surfer-犀牛-ansys的flac3d建模步骤

1、基于Gocad-surfer犀牛-ansys的flac3d建模步骤QQ：以专业地质建模软件gocad为基础，416730183借助ansys的强大建模能力，为Flac3d的建立复杂的三维地质模型。Gocad-xyz把拟合好的各地层面输出成散点，把excel中的xyz值做成txt格式。I*H13LCwi同血一L比*a中百¥通：；淳力.春Rp3Ulijacciaiij工,.,乌K|TnJhL*;ri+d二|也!C闻,同旦一宜1*工Km弋FvroraL«vtDF.Mor«tEJLjm±e与帽二：-鼻裳安EB口IcprlE4r但黎闻nMID面冷博由的巾i；3安包

4、功能不如ansys强大，不规则体的自由划分网格有时候难以实现。如果ansys用的比较熟练，不用在midas中做数据准备，这一步可以直接在ansys中完成。NVFtCE；侬I狂；几的Hl网幅的«Sll£!）甘沛STfll）THtD吉口的帆®）片口d,二±:第EM&，凰氏由0B./:与£百里遇土二人里一匹曳阿|岬I=I而ICiMMAKJT*H嘟纳jJHAMIliiaMS%./4口口中O&#宕®已0/门口AEi陋h抬4唯pprrVa/乂t»工一t布京O；1X回2融灰0Q由*B3己-Ml1|j恒>4!*I|B第
