通过hypermesh生成的cdb文件,在里面设置接触。结果在ANSYS静力计算的时候,却出现了这个。什么原因呢,应该如何处理呢?

The value of UY at node 45250 is 552447533. 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.

*** MESSAGE CONTINUATION ---- DIAGNOSTIC INFORMATION ***
If one or more parts of the model are held together only by contact
verify that the contact surfaces are closed. Also make sure that
there are constraints (or friction) in the sliding direction even if
no load is applied in that direction. You can use the CNCHECK command
to check the initial contact status in the SOLUTION module.
