在计算过程中，出现如下警告：
（1）网格划分单元有警告不必理会
（2）出现一系列类似警告，请教各位如何改正
The value of TEMP at node 70664 is 1986951.63.It is greater than the
current limit of 1000000.This generally indicates rigid body motion
as a result of an unconstrained model.Verify that your model is
properly constrained.

自己顶，希望有经验的提些修改意见

我也不会，斑竹给看看，帮帮忙啊

xpypeipei 发表于 2010-5-26 09:16:24

我的也出现这个情况，是不是不收敛了，我在想

sd9366 发表于 2010-7-4 12:59:13

看看，感谢分享
