题目内容：

请问各位ansys大神,如何查询得知一个体的具体情况?比如,我怎么知道我的v1定义的是那块体积?
是这样的,在进行了vsbv,1,2之后,是不是形成了新的体呢?也就是说,1-2之后的新体,是依然用1来表示,还是创造了一个新的体,叫做3?
这些东西用什么命令,或者在gui的哪里查看?还有,我在做一个薄膜的应力仿真,看别人写的命令流,是要不停的做wpro旋转工作平面,意义是啥?是从各种维度去划分体么?
还有一个事情是,我有个命令没看懂：CM,_Y,LINE 和CMSEL,_Y ,我看帮助,帮助说的也不太清楚,求解释.
CM
CM, Cname, Entity Groups geometry items into a component.
DATABASE: Components
MP ME ST PR PRN FL EM EH DY PP EME MFS
Cname
An alphanumeric name used to identify this component. Cname may be up to 32 characters, beginning with a letter and containing only letters, numbers, and underscores. Component names beginning with an underscore (e.g., _LOOP) are reserved for use by ANSYS and should be avoided. Components named “ALL,” “STAT,” and “DEFA” are not permitted. Overwrites a previously defined name.
Entity
Label identifying the type of geometry items to be grouped:

VOLU
?—?
Volumes.
AREA
?—?
Areas.
LINE
?—?
Lines.
KP
?—?
Keypoints.
ELEM
?—?
Elements.
NODE
?—?
Nodes.
cm 是将选择的多个线、面合成一个吗?
CMSEL,_Y ,
CMSEL
CMSEL, Type, Name, Entity Selects a subset of components and assemblies.
DATABASE: Components
MP ME ST PR PRN FL EM EH DY PP EME MFS
Type
Label identifying the type of select:

S
?—?
Select a new set (default).
R
?—?
Reselect a set from the current set.
A
?—?
Additionally select a set and extend the current set.
U
?—?
Unselect a set from the current set.
ALL
?—?
Also select all components.
NONE
?—?
Unselect all components.
Name
Name of component or assembly whose items are to be selected (valid only if Type = S, R, A, or U).
Graphical picking is enabled if Type is blank and Name = PICK (or simply “P”).
Entity
If Name is blank, then the following entity types can be specified:

VOLU
?—?
Select the volume components only.
AREA
?—?
Select the area components only.
LINE
?—?
Select the line components only.
KP
?—?
Select the keypoint components only.
ELEM
?—?
Select the element components only.
NODE
?—?
Select the node components only.
cmsel 是啥意思?

优质解答

你的问题比较多,我挑几个回答吧.
CM,_Y,LINE 和CMSEL,_Y ,第一个是建立一个component,第二个是选择这个component.有时候为了方便,常常把一些东西建立一个部件component.比如,你做车的分析,可以把轮子建立一个部件,把底盘建立一个部件等等.
不停旋转工作平面的话,这个是为了建模的方便而已,跟求解计算一般没有关系的.
