怎么给ANSYS中模型的不同部分定义材料属性
选定需要修改材料属性的单元,然后按下述顺序找到GUI命令:
preprocessor--modeling--move/modify--element--modify Attrib
在出现的对话框中选择需要修改的属性,可以修改很多属性的.
选定修改材料属性的单元后,也可以使用EMODIF命令修改:
EMODIF命令的使用请参考ANSYS使用帮助.
用英文软件,正好可以锻炼一下E文,呵呵
EMODIF
EMODIF, IEL, STLOC, I1, I2, I3, I4, I5, I6, I7, I8
Modifies a previously defined element.
PREP7: Elements
MP ME ST PR PRN FL EM EH DY PP EME MFS
IEL
Modify nodes and/or attributes for element number IEL. If ALL, modify all selected elements [ESEL]. If IEL = P, graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI). A component name may also be substituted for IEL.
STLOC
Starting location (n) of first node to be modified or the attribute label. If n, modify element node positions n, n+1, etc. (n = 1 to 20). For example, if STLOC = 1, I1 refers to the first node, I2, the second, etc. If STLOC = 9, I1 refers to the ninth node, I2, the tenth, etc. Attributes are also modified to the currently specified values (use -n to modify only nodes and not attributes). If zero, modify only the attributes to the currently specified values. If MAT, TYPE, REAL, ESYS, or SECNUM, modify only that attribute to the I1 value.
I1, I2, I3, . . . , I8
Replace the previous node numbers assigned to this element with these corresponding values. A (blank) retains the previous value (except in the I1 field, which resets the STLOC node number to zero). For attributes, replace the existing value with the I1 value (or the default if I1 is zero or blank).
