ITERATION 0
*** WARNING # 1955
Static Loadcase 1 has zero static force vector.
This typically produces zero solution and zero compliance.
(Scratch disk space usage for starting iteration = 5 MB)
WARNING: A constrained DOF is used as a response.
The value will always be specified by the SPC data.

是电脑太差？貌似在好点的电脑上Work directory: "F:/0507/" Free size 12.0 GB
显示的更大。谢谢大家！给看看咋回事！ 本帖最后由 xiaoxiaoliu 于 2012-5-8 09:32 编辑
下面我按斑竹说的把fem文件也附上 我是想优化一个梁的截面尺寸！如果谁有这方面资料麻烦分享下吧！
我看到官方网站有人问过*** WARNING # 1955

下面回复的
was this on block format? check if the skew was defined.
我不太懂
