Hi, 

Try refreshing or reopening the mechanical and see if that fixes this issue. It would be best if you did not use the rigid solid block instead you can use the shell with nominal thickness with rigid behavior something like the *RIGIDWALL feature offered in the LSDYNA. 

Based on image 2, please check if you have defined the right material properties and behaviors corrected. 

Using the velocity boundary is not advisable, use the initial velocity conditions to enforce the velocity to the cage. 

Cheers, RamÂ
