tb， 材料表（定义塑性、超弹性等）

*dim,rr,array,3，2 定义数组rr为3行2列

k,1,X，Y，Z 定义KEYPOINT1坐标

LSTR，1，2 由1、2点生成线

lesize 划分网格，尺寸定义

NUMMRG,KP, , , ,LOW 压缩节点号

asel ， 选择面

r， 定义实常数

wpro,,-90, 旋转工作平面

esln,s 选择与节点相关的单元

emodif,all,real,i 修改单元实常数

amesh 对面划分网格

type,2
mat,2
real,1
esys,0 （或 aatt） 激活单元类型2，材料号2，实常数1，单元坐标系

vsweep,all,,, 扫掠网格
.
/prep7
numstr,kp,100 !define the following keypoint number start with with the 100
l,1,2,4 !如果CSYS=0则生成直线,如果CSYS=1则生成弧线,这个命令与当前的坐标系统有关而楼上师兄的 LSTR 则始终生成直线.

lsel , !取线
wprof,,12 !移坐标
alsv !拾取一选定实体上的所有面
nsla !同理,拾取一选定面上的所有节点
aatt,1,1,1 !等效于楼上的 MAT,1 TYPE,1 REAL, 1对面定义属性

mshke,0
!网格格划分进行限定:采用FREE进行划分;网格形状为 四 边形或六面体
mshape,1,2d
vmesh ,2 !划分实体网格,后面的参数是实体编号如:2
/solu !进入求解过程
antype,static !选择求解类型为静力分析

d,all,uy,,,,,roty,rotz !对选定的面上的所有节点施加UY ROTY ROTZ 的对称约束.
allsel !恢复全部选择等效于:ASELL,ALL ESEL,ALL NSEL,ALL
asel,s,,,1
sfa,all,1,press,1000 !对选定的面1施加均布力1000
allsel
/stat,slou !显示求解状况

BEGINNER'S GUIDE TO ANSYS COMMANDS
The symbol '*' corresponds to the following:

* --> k, l, a, v, e, n, cm, et, mp, r where ==>
k --> Keypoints
l --> Lines
a --> Area
v --> Volumes
e --> Elements
n --> Nodes
cm --> component
et --> element type
mp --> material property
r --> real constant
$ --> d, f, sf, bf, ic, where ==>
d --> DOF constraint (ux... in Structural, Temp in thermal,
f --> Force Load ( Heat in thermal)
sf --> Surface load on nodes
bf --> Body Force on Nodes

More Commands can be generated by sensible combinations of " $* " family of commands. See the following list of $* possible options

$* --> dk --> DOF constraints on KP (Vx,Vy,Pres... in CFD)
dl --> DOF
constraints on Lines
da --> DOF constraints on Areas
fk --> Force on Keypoints
sfl --> Surface load on Lines
sfa --> Surface

ansys命令流中文翻译以及常用命令的介绍

load on Areas
sfe --> Surface load on element faces
bfk --> Body Force on Keypoints
bfl --> Body Force on Lines
bfa --> Body Force on Area
bfv --> Body Force on Volumes
bfe --> Body Force on Elements
ic --> Initial Conditions ",

p" --> If ",p" was issued at the end of the Command(in Input Window) the GUI based picking menu will be activated. Useful for listing, plotting, meshing, deleting, etc..

**********************************************************

1. Listing of picked Entities:
COMMAND SYNTAX: *LIS,p & $*LIS,p
A few Combinations of this command are:

klis,p --> List KP
llis,p --> Lists Lines
alis,p --> Lists Areas
vlis,p --> Lists Volumes
elis,p --> Lists Elements
nlis,p --> Lists Nodes
cmlis,p --> Lists components
cslis,p --> Lists user created local co-ordinate systems
dlis,p --> Lists DOF constraints specfied on nodes
dalis,p --> Lists DOF constraints applied on Areas
flis,p --> Lists force on Nodes
sfllis,p --> Lists Surface Load on lines
bfalis,p --> Lists body force load applied on Areas
iclis,p --> Lists Initial condition on Nodes

If ",p" was not issued, all entites currently selected will be listed.
For certain commands ",p" cannot be issued. See the below mentioned commands

etlis --> Lists the different element types defined
mplis --> Lists whatever Material properties
rlis --> Lists whatever real constants
cslis --> Lists all co-ordinate systems
cmlis --> Lists all components

*********************************************************

2. Plotting of Entities: COMMAND SYNTAX: *plo KPLO / LPLO / APLO / VPLO / EPLO / NPLO / CMPLO /

**********************************************************

3. deleting of Entities:
COMMAND SYNTAX: *DEL,p & $*DEL,p
KDEL,p / LDEL,p / ADEL,p / VDEL,p / EDEL,p / NDEL,p / CMDEL,p / DDEL,p /
DKDEL,p / DADEL,p / FDEL,p / SFDEL,p / SFEDEL,p / SFADEL,p / SFLDEL,p /
BFADEL,p / ......
The syntax for this command is very similar to LISTING command.

**********************************************************

4. distance between two entities:
COMMAND SYNTAX: *DIS,p
ndis,p --> Distance between two nodes
kdis,p --> Distance between two KPs

**********************************************************

5. Meshing of geometries:
COMMAND SYNTAX: *MES,p
KMES,p / LMES,p / AMES,p / VMES,p
