【讨论】接触问题请教?
我做橡胶和刚体的接触,总是出下面的错误不知道该怎么改No element connection for node 864 direction 3
No element connection for node 865 direction 3
No element connection for node 866 direction 3
No element connection for node 867 direction 3
No element connection for node 868 direction 3
No element connection for node 869 direction 3
No element connection for node 870 direction 3
No element connection for node 871 direction 3
No element connection for node 872 direction 3
No element connection for node 873 direction 3
No element connection for node 875 direction 3
Nodal degrees of freedom without element
connection have been fixed for ADINA input data.
There may still be degrees of freedom without
stiffness - see documentation.
*.in文件附在下面,如果里面还有什么样的问题请多多指教

关掉 Z向平移自由度试试回复: 【讨论】接触问题请教?
谢谢,上面的问题我用“约束”解决了,但是我即使设置刚体位移为0也会出现如下问题,那位大侠帮我看看
