陈育民《FLAC3D基础与工程实例》全部命令流

FLAC-命令流及其解释⼤全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. Fish是什么东西？答：是FLAC3D的内置语⾔，可以⽤来进⾏参数化模型、完成命令本⾝不能进⾏的功能21. Fish是否⼀定要学？答：可以不⽤，需要的时候查Mannual获得需要的变量就可以了22. FLAC3D允许的命令⽂件格式有哪些？答：⽆所谓，只要是⽂本⽂件，什么后缀都可以23. 如何调⽤⼀些可选模块？答：config dyn (fluid, creep, cppudm)后注：这个⼯作很繁琐，需要的时间很多，希望⼴⼤⽹友能够将⾃⼰曾经遇到的常见问题在后续跟贴，也为了将这个FAQ进⾏很好的充实。

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。

2. range(缩写：ran)通过range功能，可以使命令作用在一定指定范围的目标上；如果一个命令没有使用range来确定范围，则命令对整个模型有效。

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。

1、何如查看模型？之阳早格格创做问：plot grid 不妨查看网格，plot grid num 不妨查看节面号.2、请问正在圆柱体四里怎么样施加拘束条件？问：不妨用fix ... ran cylinder end1 end2 radius r1 cylinder end1 end2 radius r2 not，其中r2<r1，本去便是采用range的时间选二个圆柱的好，即得到鸿沟.下令流如下：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的图像数据导出去以便用其余硬件画图？问：用set log on 下令，把数据导出去，转到excel里处理一下，而后用surfer大概者什么做图硬件画造便止了.4、用下令建坐模型后，怎么样隐现面的坐标？问：使用plo blo gro gpnum on下令5、关于gauss_dev对于本量举止下斯正态分集的问题？问：根据脚册上的证明：底下的下令设定一个仄稳摩揩角为40度，尺度圆好是±5％.则下令如下：prop friction 40 gauss_dev 2问题：请问gauss_dev 2中的2是怎么样估计的？如果把±5％改为±10％，则下令应怎么样写？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 （对于xy里搞镜像）gen zone reflect dip 90 dd 90 （对于yz里搞镜像）（1）dd表示y轴正背顺时针到那条射线的夹角，dip表示对于称参照里与xy仄里的夹角，对于称参照里与xy仄里的夹角正在xy仄里的投影是一条射线.最先该当依照dd的目标大概决定那个里的往背，dd 指的是从y轴正目标按顺时针（clockwise）目标转背所要决定里的法线目标正在xy仄里上的投影的夹角，而后再决定dip，dip指的是从xy仄里转背所要决定的仄里的角．（及z轴背目标转过角度）（2）下令：reflect normal xyz origin xyz （根据法线战过一面建的里）最时常使用，至于本量使用历程中有人问道：normal -1 0 0 与normal 1 0 0的辨别，尔试过二者的效验是一般的，出辨别，虽然目标分歧，但是表黑的是共一个里.reflect dd a dip b origin xyz 那个便是用里建坐斜里镜像的.有一面注意了，镜像的时间如果是模型镜像的话，相称于正在建坐一个模型，故，正在reflect的前里要加建模的关键字，gen zone reflect……7、关于二种fix是可有辨别？fix z range z -0.1 0.1fix x range x -0.1 0.1 any x 1.9 2.1 anyfix y range y -0.1 0.1 any y 1.9 2.1 any战fix z range z -0.1 0.1fix x range x -0.1 0.1fix x range 1.9 2.1fix y range y -0.1 0.1fix y range y 1.9 2.1问：是一般的，any表示并列对接关系，及and的意义.8、initial apply set 的辨别问：initial 初初化下令，初初化估计应力状态，定义资料参数、重力等；apply鸿沟条件节造下令，如施加鸿沟的力、位移等拘束等；set 用于树坐估计的模式，统造估计历程.Ini 施加的初初力正在估计历程中是会变的，普遍体力需要初初化，而apply施加的力、鸿沟条件不会随着估计变更.set下令效率于所有网格(赋值局部变量),ini则初初化指定范畴内网格面、域的偏偏移量.初初应力不但是仅是重力引起的.9、Tension-p shear-p tension-n shear-n表示的含意问：正在估计的循环内里,每个循环中,每个zone 皆依据failure criterion 处于分歧的状态,shear战tension 分别表示果受剪战受推而处于塑性状态.n 表示now,p表示previous,即分别表示正在当前战往日的循环核心处于塑性状态.10、history保存数据，print隐现正在过失的下令流中“”文献中惟有：“Step 1 Y-Displace”而不保存下数值，怎么回事？尔怎么才搞赢得table中的数据？输进'print tabel n'能得到table中的数据（粗确）hist gp ydisp 0,0,0hist zone syy 0,1,0hist zone syy 1,1,0step 3000hist write 1 file 本面位移.dathist write 2 file 中部单元应力.dathist write 3 file 边沿单元应力.dathist write 1 table 1hist write 2 table 2hist write 3 table 3hist write 2 3 vs 1 file 单压.dat（过失）hist gp ydisp 0,0,0hist zone syy 0,1,0hist zone syy 1,1,0hist write 1 file 本面位移.dathist write 2 file 中部单元应力.dathist write 3 file 边沿单元应力.dathist write 1 table 1hist write 2 table 2hist write 3 table 3hist write 2 3 vs 1 file 单压.datstep 300011、plot隐现x、y坐标图hist n 1hist gp ydisp 0,0,0hist ax_strhist gp xdisp 1,1,0step 1500plot hist 2 vs -1 ;axial stress vs axial disp.plot hist 3 vs -1 ; circumferential disp. vs axial disp问：那2是不是代表hist gp ydisp 0,0,0，而-1 指得是hist gp ydisp 0,0,0为什么不是1而是背值？1) 正在plot hist m vs n的形式里,m代表y轴,n代表x轴(不管m,n的正背);2) "-"表示对于其值做"mirror",如果大家使用AUTOCAD的话便明黑"mirror"的含意了,比圆上头的 hist 1 gp ydisp的值是0~100,那么vs -1便形成-100~0.以此类推.3) 要那样搞主假如为了切合岩土工程的习惯需要,比圆桩载荷考查直线,重落直线等皆不是画正在第一象限内.12、关于water.fis的下令注释（树坐天下火位）问：（1）water.fis的功能是树坐天下火位里，正在二维估计中，通过water table下令即可树坐火位线，正在三维估计中由于天下火位是里，果此需要做一些插值运算，以便产死火位里.那个FISH步调包罗三个函数parm,aux1战aux2.parm用去设定火位的边值，即树坐火位的天区，aux1插值估计等值线的面，aux2调用aux1的估计截止，使用FLAC3D 下令产死火位里.（2）最先树坐参数值，而后定义一个table.def parmnptab1=7nprof=10endparmtable 1 (12 0) (18.25 12.5) (25 17) (35 21) (50 24) (75 25) (150 25)爆收table1，包罗7组数据面.3) 正在阐明的二个FISH函数之前，对于table,xtable,ytable做一些总的证明.water.fis步调反复使用了那三个变量，明黑了那三个变量的含意，water.fis那段步调便办理了大半问题了.Itasca 的所有硬件皆使用了相共的数据结构储藏数据，称之为链表结构，类似于关系型数据库中的数据链接要领.如果罕见据结构的知识，大概掌握关系型数据库的SQL 谈话，那三个变量的含意便不易明黑了，只不过那个支配与真真的数据库支配相比，惟有二个数据变量x,y.尔用数据库的术语做阐明：table 便是爆收一个“表”，xtable,ytable的效率便是爆收一个新表(Create)以及对于表中的数据举止与出(Select)、拔出(Insert)、替换(Update)支配.4）FISH函数aux1的效率是正在table 1的前提上爆收出其余个table，table的ID 从11到17，每个table有10个数据集.alfa的估计要领是为切合(fit)直里而采与的坐标面算法.def aux1loop n(1,nptab1)rr=xtable(1,n)zz=ytable(1,n)loop k(1,nprof)case_of kalfa=0.5*(pi+.1)*float(k-2)/float(nprof-2)xtable(n+10,k)=rr*cos(alfa)ytable(n+10,k)=rr*sin(alfa)case 1xtable(n+10,k)=rrytable(n+10,k)=-40.0case 2xtable(n+10,k)=rrytable(n+10,k)=0.0end_caseend_loopend_loopendaux1当真止那个FISH函数后，死成(nptab1+10,nprof)组数据，那些数据为Aux2调用.注意：本段步调爆收的数据是为那个特定的直里边坡创造的，不是一个general purpose的LIB5）FISH函数aux2的效率是使用WATER TABLE face下令爆收火里，把table 1的ytable值动做z坐标，aux1爆收的数据动做x,y坐标.def aux2commandset grav 0 0 -10water dens 1000end_commandloop n(1,nptab1-1)loop k (1,nprof-1)xx1=xtable(n+10,k)yy1=ytable(n+10,k)zz1=ytable(1,n)xx2=xtable(n+10,k+1)yy2=ytable(n+10,k+1)zz2=zz1xx3=xtable(n+11,k+1)yy3=ytable(n+11,k+1)zz3=ytable(1,n+1)xx4=xtable(n+11,k)yy4=ytable(n+11,k)zz4=zz3commandWATER TABLE face xx1,yy1,zz1 xx2,yy2,zz2 xx3,yy3,zz3WATER TABLE face xx1,yy1,zz1 xx3,yy3,zz3 xx4,yy4,zz4end_commandend_loopend_loopendaux213、 FLAC截止数据的导出pl set back white ;树坐背景set plot bitmap size (800,510) ;树坐图片大小plot set caption size 37 ;
