我觉得也是约束的问题，我再仔细的检查一下，谢谢了啊 2# hyyfj
现在提示我出现以下的错误
There were 20 error messages during input processing.
The first message is repeated below:
***ERROR # 725 *** in the input data:
An invalid rigid element.
This RBE2 has rotational rigid body modes in all three derections.
RBE2 element id = 7487659
independent grid id = 1209440
Note: If this rigid element is also connected with other rigid elements,
then this error means that there is rigid body mode or mechanism remained
in this rigid element chain due to lack of connected structural elements.
请帮忙分析下问题，麻烦一下了 我的opt怎么不能求解啊 4# 雨沐枫
检查一下RBE2的主节点是否有足够的约束 - 它需要和结构其他部分连接，或者自己有SPC约束位移。 1# 雨沐枫
把位移约束删掉，重新定义。
你原来的模型中SPC卡片的的第3个字段(field#3)是0, 这是不对的，因为它定义的是节点编号(必须是>0的整数)。 详情可查看OptiStruct帮助文档中关于SPC卡片的介绍。
