load displacement, shells are not parallel

Altair Forum User

Hallo ，

I have a question.

I loaded the displacement, but I don't know, why the upper and lower shells are not parallel ？

the contact has no problem.   

How can I fix it?

 

Thank you very much!

you should constrain the rigids on top and bottom plates also in rotational degrees of freedom (DOF 4-6).
