upcoord 命令帮助的一点补充
-------------------------------------------------------------------------------------------------------------------------------------------------------------------UPCOORD, FACTOR, Key
Modifies the coordinates of the active set of nodes, based on the current displacements.
FACTORScale factor for displacements being added to nodal coordinates. If FACTOR = 1.0, the full displacement value will be added to each node, 0.5, half the displacement value will be added, etc. If FACTOR = -1, the full displacement value will be subtracted from each node, etc.
KeyKey for zeroing displacements in the database:
OFF
— Do not zero the displacements (default).
ON
— Zero the displacements.

以上是ANSYS帮助手册里关于upcoord命令的解释。但是应该注意该命令在后处理模块/post1里是无效的...因此，以后应用该命令，一定要切换到/prep7或/solu模块执行....
[ 本帖最后由 snrit 于 2007-12-2 11:17 编辑 ] 我想问一下这个factor是根据什么来定义怎么定义 我看过很多例子有的factor为0.001
还有就是我想问一下这个factor如果像上面说的为0.5意思就是在先前分析得到的变形缩小一半 但是如果先前的特征值屈曲分析提取了不止一个模态那么施加初始缺陷时这个0.5应该考虑用在哪个模态上
谢谢了
