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).

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）
下下面面这这代代码码，，是是沿沿着着--yy方方向向的的重重力力加加速速度度，，注注意意区区别别！！！！！！！！
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 zone
gen 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 zone
Undo ;撤销命令
set logfile 127X1001.txt set log on truncate
set log off
list 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 type list hist
for 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1次 hist add ratio ; 记录maximum unbalanced force ratio hist 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,enter The 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 logic is specified
ini xdis 0 ydis 0 zdis 0 ;位移归零 solve
save trench ; 保持计算结果的文件 “TRENCH.F3SAV” 不需要后
缀
4、group命令(注意新版本的区别 ，group zone)
gen zone brick size 6 6 6
group zone Tunnel range x 1 6 y 0 6 z 1 5 ;设置group
model mech mohr ; 莫尔库伦模型 model mech null range group Tunnel ;
group zone Tunnel range cylinder end1 100 105 100 end2 100 95 100 radius 3 group zone Matrix range group Tunnel not
