cad 图形导入ANSYS中的步骤
1、一般步骤
1)绘制好CAD图形,输出.SAT格式文件。
2)打开ANSYS文件,输入.SAT格式文件。
2、若CAD图形仅为线段组成,则如何输出.SAT格式文件。
2010版本CAD仅支持面域、实体或 ShapeManager
体的对象输出,对于线段则无法输出,需使用boundary命令形成面域,该面域性状可谓矩形,也可为异性。
CAD对需要生成面域的原始线段是有较高要求的,一般用矩形命令绘制的四边形才能形成面域。这时,在CAD中,我一般按如下步骤操作:
1)在CAD中建立不同图层,而且为需要生成面域的线段单独建立一个图层;
2)按不同图层建立完整的分析模型,打开面域图层,在整个模型上使用矩形命令临摹出很多矩形,便于后续生成我想要的面域。
3)关闭其他图层,打开面域图层,输出SAT文件。
3、打开ANSYS
FINISH ! Make sure we are at BEGIN level
/CLEAR,NOSTART ! Clear model since no SAVE found
~SATIN,zhuangtype1,sat,'..\cad picture\',SOLIDS,0
AOVLAP,ALL
4、导入失败案例解决方法
之前在ANSYS
14.5中曾成功导入二维面和线,使用的命令为:~SATIN,zhuangtype1,sat,'..\cad
picture\',SOLIDS,0。之后安装了 ANSYS
16.0,使用同样的命令则无法成功导入。查看HELP文件,发现将命令改为SATIN,zhuangtype1,sat,'..\cad
picture\',ALL,0即可成功。原因是需正确设置导入对象的类型,如SOLIDS、SURFACES、
WIREFRAME或ALL,当无法确认导入对象类型时,选ALL较为保险。

Transfers a
.SAT
file into the ANSYS program.
CAD Import
MP ME ST PR PRN <> EM DY PP EME MFS
Name
- The name of a valid
.SAT
file, created with a supported version of ACIS.
The first character of the file name must be an alphanumeric.
Special characters such as & - and * and spaces are not
permitted in the part name. See File
Names in the Command
Reference for more information about
ANSYS file naming conventions.
Extension
- The extension for the file. The default extension is
.sat.
Path
- The path name of the directory in which the file resides
enclosed in single quotes. The default path name is the current
working directory.
Entity
- Entity to be imported.
SOLIDS
|
— |
Solids only, imported as ANSYS volumes (Not implemented,
imports
All).
|
SURFACES
|
— |
Surfaces only, imported as ANSYS areas (Not implemented,
imports
All).
|
WIREFRAME
|
— |
Wireframe only, imported as ANSYS lines (Not implemented,
imports
All).
|
ALL
|
— |
All entities. Use this option when the file contains different
types of entities.
|
FMT
- The format in which ANSYS will store the model.
0
|
— |
Neutral format (default). Defeaturing after import is
restricted.
|
1
|
— |
Solid format; this allows defeaturing after import.
