Introduction to Inquiry Functions [John Crawford]:
Here is just about everything I know about inquiry functions.
They are similar to *GET functions in usage, and have two
input arguments. Here's an example.
a=ndinqr(33,1)
In this case, "a" will be assigned a value of -1 if node 33
is
unselected, 0 if it is undefined, and 1 if it is selected.
This is an example of using an inquiry function to obtain
information about a specific entity, in this case node 33.
An alternative use of an inquiry function is to find more
generic data about a certain kind of entities. The following
example illustrates this.
a=ndinqr(0,14)
This will assign to parameter "a" the highest node number
defined in the model. Notice that the first argument is zero,
and the second argument is 14.
Here are the inquiry functions I am aware of.
ndinqr(node,key) node number or zero, and key number
elmiqr(elem,key)
kpinqr(keypoint,key)
lsinqr(line,key)
arinqr(area,key)
vlinqr(volume,key)
rlinqr(real,key)
gapiqr(gap element,key)
masiqr(master DOF,key)
ceinqr(constraint equation,key)
cpinqr(coupled set,key)
csyiqr(coord system,key)
etyiqr(element type,key)
foriqr(nodal force,key)
All of these work pretty much the same, with the first
argument used as either an entity ID number (for data about a
specific node, element, etc.) or a zero if the information is
about a class of element (number of selected nodes, etc.)
The key numbers are defined as follows.
key=1 return select status (for a specific entity)
key=12 return number of defined entities (KP's, nodes, etc.)
key=13 return number of selected entities
key=14 return the highest ID number in use
There a few other inquiry functions which have a slightly
different format.
mpinqr(mat,prop,key) material property table number, property
number, key additional key=3 for number of temps used in a
specific property
dget(node,idof,kcmplx) node number, displacement pointer,
complex key displacement pointers are...
1=ux, 2=uy, 3=uz, 4=rotx, 5=roty, 6=rotz, 7=ax, 8=ay 9=az,
10=vx, 11=vy, 12=vz, 19=pres, 20=temp, 21=volt, 22=mag,
23=enke, 24=ends, 25=emf, 26=curr
complex key=0 for real, 1 for imaginary
fget(node,idof,kcomplx) same definition as dget, but for
forces this time

Inquiry Functions for Sections [Grama Bhashyam]:
I have looked at the code and can confirm Tyllinen Juha's
observation. It will work in 5.5, 5.6, and not likely to
change.
"Quick testing seems to indicate that Section number would be
available with sn = elmiqr(n,-4), where n is the element
number. At least that is the way it worked in 5.5.1 with
Beam188 and Beam189."
Other possibilites for element characteristics
-1, material number
-2, element type
-3, real constant number
-4, Element Section ID number
-5, coordinate system number

Additional Inquiry Function [Juha Tyllinen]:
Some time ago I dug out one additional Key:
NUMS value for the entity:
ndinqr(0,25)
elmiqr(0,25)
kpinqr(0,25)
lsinqr(0,25)
arinqr(0,25)
vlinqr(0,25)
It is sometimes handy for use in macros.

不用搞得这么复杂，这个命令已经公布了吧，欧好像用过，就是ANSYS 查询函数（Inquiry Function）贴出来给大家看。

在ANSYS操作过程或条件语句中，常常需要知道有关模型的许多参数值，如选择集中的单元数、节点数，最大节点号等。此时，一般可通过*GET命令来获得这些参数。现在，对于此类问题，我们有了一个更为方便的选择，那就是查询函数 — Inquiry Function。
    Inquiry Function类似于ANSYS的 *GET 命令，它访问ANSYS数据库并返回要查询的数值，方便后续使用。ANSYS每执行一次查询函数，便查询一次数据库，并用查询值替代该查询函数。

NODE—ndinqr(node,key)
node—节点号，对于key=12,13,14为0
key—标识关于node的返回信息
=1， 选择状态
=12，定义的数目
=13，选择的数目
=14，定义的最大数
=-2，超单元标记
=-3，主自由度
=-4，激活的自由度
=-5，附着的实体模型
ndinqr(node,key)的返回值
对于key=1
=-1,未选择
=0，未定义
=1， 选择

ndinqr(node,key)
是一个函数，
比如ndinqr(0,13) 等于你当前所选择的节点的数目
