建 模1、调用文件：①文件与工程在同一个文件夹，只写文件名即可：If the called file is located in the same folder as the FLAC3D project file, then only the file name need be entered with the CALL command. ②不在同一个文件夹，全路径：Otherwise, the file may be called by specifying its complete path (e.g., c:\myfolder\file.dat).Undo ;撤销上一条命令2、创建 旋转 缩放视图3、建模命令model mech mohr ;莫尔库伦模型 model mech elastic ;弹性模型set grav 0, 0, -9.81 ; 重力加速度 negative z-direction. （垂直向下！常用的）下面这代码，是沿着下面这代码，是沿着下面这代码，是沿着-y-y -y 方向的重力加速度，注意区别！！！！方向的重力加速度，注意区别！！！！方向的重力加速度，注意区别！！！！gen zone brick size 6,8,8 p0 -10, -10, -20 . ;省略号表示写不下后面继续p1 10, -10, -20 .p2 -10, 10, -20 .p3 -10, -10, 0 plot zonegen zone brick size 6,8,8 p0 -10, -10, -20 . ;不规则六面体 p1 10, -10, -20 p2 -10, 10, -20 . p3 -10, -10, 0 p4 10, 10, -20 . p5 -10, 10, 10 p6 10, -10, 0 . p7 10, 10, 10 plot current plot Plot01 plot clear plot zoneUndo ;撤销命令set logfile 127X1001.txt set log on truncateset log offlist zone prin range x 0 1 y 0 1 z 0 1 ;显示指定范围内各单元的主应力，结果如下Hist 命令： ① 命令编号按顺序从 1 开始：each history is numbered sequentially from 1 as it is entered via the HISTORY command. ②查找显示所有的 his 命令：Return to the Flac3D> prompt and typelist histfor a listing of the histories and their corresponding numbers.hist nstep 5 ;每 5 步记录 1 次。

（在 x-y 面上，从 y 的正方向开始沿顺时针方向计量），过 x-y 面上一点 （x=3,y=4,z=0）,在平面后加一个网格，垂直方向的应力 Qzz，最后给模型加轴 线，整体图形轮廓与添加图形相反，显示每个区域中心的应力计算值，每个区 域的颜色直接对应基本区域的应力，当键入 show,我们建立的图形被显示 Plot create Dispcont Pl add cont disp plane behind Pl add axes Pl show plot sketch ;绘出轮廓线 plot add vel ;添加矢量 plot add his 1 2 vs 3;绘出历史记录 n，actLoad ， p_sol cyc 15000plot Create Trench Add surface yellow Add axes black Showplot create szz_contour ;创建文件名为 szz_contour（z 方向的应力云图） plot set cent 4 4 5 ;视图的中。
