计算水槽晃动模型提交报错

shuqi_chen

我在模仿帮助文档中水槽晃动的分析实例时总是会提示如下错误
Error in job ddddddddd: *CONTACT INCLUSIONS, ALL EXTERIOR has been used or a blank first surface name was specified under *CONTACT INCLUSIONS or *CONTACT EXCLUSIONS, but the model does not contain any 3D elements from which the contact domain can be constructed.
是接触错误
可是我在查看关键字时发现和例子中的接触设置是一致的
很头痛
