1、建 模1、调用文件: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 needbe entered with the CALL command. 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:myfolderfile.dat).Undo ;撤销上一条命令2、创建 旋转 缩放视
2、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.

4、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: 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.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。默认是 10 步记录
5、1 次hist add ratio ; 记录 maximum unbalanced force ratiohist add gp zdisp 4 4 8 ;记录节点的位移model null range x=2,4 y=2,6 z=5,10 ;To excavate the trench,enterThe dimensions of the excavation region (i.e., the null material) are defined by the x-, y- and z-coordinate range.set large ; 设置大变形 large-strain logi
