FLAC3D常用命令总结

FLAC3D常用命令总结第一篇：FLAC3D常用命令总结1、模型建好如何检验所建模型是否有问题注意：第一步建模一定不要建太大的模型，可以建非常小的模型，确保模型的准确性，这样可以尽快开始后边的步骤，等后边计算分析步骤快速做完验证没有大问题，再将准确的模型建好换上，重新计算得到更加准确的结果。

2、如何检验应力边界、位移边界、加载速率等是否准确Plot add gpfix：看位移边界Plo add fap：看应力边界，看加载方向是否准确 Plot add vel：看速率，加载速率是否准确3、如何查看运算结果Plo con szz outline on：看z向应力云图，并显示边界网格 Plo add disp：看位移Plo con zdisp outline on magf 5：看z向位移云图，变形扩大5倍 Plo add bo ：添加边界 Plo blo state：看是否屈服Plo add stensor：查看大主应力方向Plo con smin：小主应力Plo con smax：大主应力Plo con ssi（shear strain increment）：查看剪切应变增量云图Plo bcont smin：查看单元小主应力4、如何做切面并查看切面结果在编辑“Edit“菜单中设置切面位置，在上述3命令后加上plane （pl）即可。

如：Plo con smin pl：查看切面小主应力5、后处理将模型导入到tecplot中做切面，加等值线等，对结果进一步处理，得到更漂亮的一些结果。

其他重要命令总结：1、如何在圆柱体四周如何施加约束条件？可以用fix...ran cylinder end1 end2 radius r1 cylinder end1end2 radius r2 not，其中r22、如何能把一个PLOT的图像数据导出来以便用其他软件绘图？答：用set log on 命令，把数据导出来，转到excel里处理一下，然后用surfer或者什么作图软件绘制就行了。

（完整版）FLAC3D命令流（整理版）

1、怎样查看模型？答：plot grid 可以查看网格，plot grid num 可以查看节点号。

可以查看节点号。

2、请问在圆柱体四周如何施加约束条件？答：可以用fix ... ran cylinder end1 end2 radius r1 cylinder end1 end2 radius r2 not ，其中r2<r1，其实就是选择range 的时候选两个圆柱的差，即得到边界。

命令流如下：差，即得到边界。

命令流如下：fix x range end1 1 0 0 end2 1 4 0 rad 1 end1 1 0 0 end2 1 4 0 rad 13、怎么能把一个PLOT 的图像数据导出来以便用其他软件绘图？答：用set log on 命令，把数据导出来，转到excel 里处理一下，然后用surfer 或者什么作图软件绘制就行了。

或者什么作图软件绘制就行了。

4、用命令建立模型后，如何显示点的坐标？答：使用plo blo gro gpnum on 命令命令5、关于gauss_dev 对性质进行高斯正态分布的问题？答：根据手册上的说明：下面的命令设定一个平均摩擦角为40度，标准方差是±5％。

则命令如下：prop friction 40 gauss_dev 2问题：请问gauss_dev 2中的2是如何计算的？如果把±5％改为±10％，则命令应如何写？40×5％＝26、 reflect 问题问：gen zone radbrick &p0 (0,0,0) p1 (10,0,0) p2 (0,10,0) p3 (0,0,10) &size 3,5,5,7 &ratio 1,1,1,1.5 &dim 1 4 2 fillplot surfgen zone reflect dip 0 dd 90 （对xy 面做镜像）面做镜像）gen zone reflect dip 90 dd 90 （对yz 面做镜像）面做镜像）（1）dd 表示y 轴正向顺时针到那条射线的夹角，dip 表示对称参照面与xy 平面的夹角，对称参照面与xy 平面的夹角在xy 平面的投影是一条射线。

FLAC3D命令流(挺实用)

1、怎样查看模型？答：plot grid 可以查看网格，plot grid num 可以查看节点号。

2、请问在圆柱体四周如何施加约束条件？答：可以用fix ... ran cylinder end1 end2 radius r1 cylinder end1 end2 radius r2 not，其中r2<r1，其实就是选择range的时候选两个圆柱的差，即得到边界。

命令流如下：fix x range end1 1 0 0 end2 1 4 0 rad 1 end1 1 0 0 end2 1 4 0 rad 13、怎么能把一个PLOT的图像数据导出来以便用其他软件绘图？答：用set log on 命令，把数据导出来，转到excel里处理一下，然后用surfer或者什么作图软件绘制就行了。

4、用命令建立模型后，如何显示点的坐标？答：使用plo blo gro gpnum on命令5、关于gauss_dev对性质进行高斯正态分布的问题？答：根据手册上的说明：下面的命令设定一个平均摩擦角为40度，标准方差是±5％。

则命令如下：prop friction 40 gauss_dev 2问题：请问gauss_dev 2中的2是如何计算的？如果把±5％改为±10％，则命令应如何写？40×5％＝26、reflect问题问：gen zone radbrick &p0 (0,0,0) p1 (10,0,0) p2 (0,10,0) p3 (0,0,10) &size 3,5,5,7 &ratio 1,1,1,1.5 &dim 1 4 2 fillplot surfgen zone reflect dip 0 dd 90 （对xy面做镜像）gen zone reflect dip 90 dd 90 （对yz面做镜像）（1）dd表示y轴正向顺时针到那条射线的夹角，dip表示对称参照面与xy平面的夹角，对称参照面与xy平面的夹角在xy平面的投影是一条射线。

FLAC3D与FLAC常见命令的整理

FLAC/FLAC3D常规问题的整理1．FLAC3D命令的FAQlakewater整理看到其它板块上都有这个FAQ，也就是常见问题问答，今天抽了时间进行了整理，想到了就写下来了，因为看到很多初学者费了很多的时间，但是还是没有将常用的命令掌握，所以这个也可以作为入门的初级教材，使大家能够快速的上手，而不用为了某个小命令到处求助。

1. FLAC3D是有限元程序吗？答：不是！是有限差分法。

2. 最先需要掌握的命令有哪些？答：需要掌握gen, ini, app, plo, solve等建模、初始条件、边界条件、后处理和求解的命令。

3. 怎样看模型的样子？答：plo blo gro可以看到不同的group的颜色分布4. 怎样看模型的边界情况？答：plo gpfix red sk5. 怎样看模型的体力分布？答：plo fap red sk6. 怎样看模型的云图？答：位移：plo con dis (xdis, ydis, zdis)应力：plo con sz (sy, sx, sxy, syz, sxz)7. 怎样看模型的矢量图？答：plo dis (xdis, ydis, zdis)8. 怎样看模型有多少单元、节点？答：plo info9. 怎样输出模型的后处理图？答：File/Print type/Jpg file，然后选择File/Print，将保存格式选择为jpe文件10. 怎样调用一个文件？答：File/call或者call命令10. 如何施加面力？答：app nstress11. 如何调整视图的大小、角度？答：综合使用x, y, z, m, Shift键，配合使用Ctrl+R，Ctrl+Z等快捷键12. 如何进行边界约束？答：fix x ran （约束的是速度，在初始情况下约束等效于位移约束）13. 如何知道每个单元的ID？答：用鼠标双击单元的表面，可以知道单元的ID和坐标14. 如何进行切片？答：plo set plane ori (点坐标) norm (法向矢量)plo con sz plane (显示z方向应力的切片)15. 如何保存计算结果？答：save +文件名16. 如何调用已保存的结果？答：rest +文件名；或者File / Restor17. 如何暂停计算？答：Esc18. 如何在程序中进行暂停，并可恢复计算？答：在命令中加入pause命令，用continue进行继续19. 如何跳过某个计算步？答：在计算中按空格键跳过本次计算，自动进入下一步20.

(总结452类)FLAC3D命令流挺实用

、怎样查看模型？答：可以查看网格，可以查看节点号。

、请问在圆柱体四周如何施加约束条件？答：可以用... ，其中<，其实就是选择的时候选两个圆柱的差，即得到边界。

命令流如下：、怎么能把一个的图像数据导出来以便用其他软件绘图？答：用命令，把数据导出来，转到里处理一下，然后用或者什么作图软件绘制就行了。

、用命令建立模型后，如何显示点的坐标？答：使用命令、关于对性质进行高斯正态分布的问题？答：根据手册上的说明：下面的命令设定一个平均摩擦角为度，标准方差是±％。

则命令如下：问题：请问中的是如何计算的？如果把±％改为±％，则命令应如何写？×％＝、问题问：() () () ()（对面做镜像）（对面做镜像）（）表示轴正向顺时针到那条射线的夹角，表示对称参照面与平面的夹角，对称参照面与平面的夹角在平面的投影是一条射线。

首先应该按照的方向大体确定这个面的朝向，指的是从轴正方向按顺时针（）方向转向所要确定面的法线方向在平面上的投影的夹角，然后再确定，指的是从平面转向所要确定的平面的角．（及轴负方向转过角度）（）命令：（根据法线和过一点建的面）最常用，至于实际使用过程中有人问道：与的区别，我试过两者的效果是一样的，没区别，虽然方向不同，但表达的是同一个面。

这个就是用里建立斜面镜像的。

有一点注意了，镜像的时候如果是模型镜像的话，相当于在建立一个模型，故，在的前面要加建模的关键字，……7、关于两种是否有区别？和答：是一样的，表示并列连接关系，及的意思。

8、的区别答：初始化命令，初始化计算应力状态，定义材料参数、重力等。

边界条件限制命令，如施加边界的力、位移等约束等。

用于设置计算的模式，控制计算过程。

施加的初始力在计算过程中是会变的，一般体力需要初始化，而施加的力、边界条件不会随着计算变化。

命令作用于整个网格(赋值全局变量)则初始化指定范围内网格点、域的偏移量。

初始应力不仅仅是重力引起的。

1）利用坐标指定一定的范围格式1：range z 0 1格式2：range z 2.9 3.1 x 1 2 y 1 22）利用分组来指定范围格式：range group 13）以上两种的复合格式：range z -0.1 0.1 group pile4）利用id 号来指定一定的范围格式：range id 0 10该命令后跟起始id 和结束id，这里的id 可以是实体单元、网格、结构单元、接触面和节点的编号。

例：model elastic range id 1 10 ;指定id 为1到10的单元为各向同性弹性本构。

5）命名一个范围（需要先命名这个范围）格式：range name <自己起一个名字> <范围> 示例：range name intersected_zones x 5 8 y 3 7 引用这个范围的格式：内容+range nrange <自己起的那个名字> 示例：range nrangeintersected_zone6）命名一个柱形范围格式：同4）示例1：range name bhole cylinder end10 0 0 end2 -9.14 0 0 rad 0.46示例2：range name interface1 cylinder end1 0 0 0 end2 0 0 -0.9 radius 0.36 &cylinder end1 0 0 0 end2 0 0 -0.9 radius 0.34 not 7）any 和notAny 跟在range 命令后表示“和”的意思，即使若干个定义的范围同时起效；not 跟在range后表示“除了”的意思，即除此之外的范围示例1：group wall range group 1 any group 2 any ;把组 1 和组 2 定义为新组，组名为wall示例2：group wall range group 1 not ;把除了组 1 之外的所有部分定义为新组，组名为wall.示例3：range name interface1 cylinder end1 0 0 0 end2 0 0 -0.9 radius 0.36 &cylinder end1 0 0 0 end2 0 0 -0.9 radius 0.34 not3. set 用来设置重力、收敛标准、给某些变量赋值1）设置重力格式：set gravity 0 0 -102）设置收敛标准格式1：set mech ratio <value> :用R 无量纲值确定收敛标准（默认10e-5）格式2：set mech force ＜value＞ ;绝对收敛标准，体系最大不平衡力小于某一临界值，此局限性较大。
