没懂你的意思 终于有人回贴了,我的意思就是定义实常数的时候,我怎么知道定义给了哪个材料? <P>实常数编号,需要指定.</P> <P><BR>R只是定义实常数编号,Real命令是制定实常数编号与单元编号相关,Set number relates to that defined with the element [<a href="mk:@MSITStore:D:\Program%20Files\Ansys%20Inc\v80\commonfiles\help\en-us\ansyshelp.chm::/Hlp_C_REAL.html" target="_blank" ><B>REAL</B></A>]. Note that the GUI automatically sets this value<BR>可能是使用了默认值</P> <P>谢谢楼上的了 ,我想也是这个意思!</P>
