How to make two boundary lines move in parallel?

Hi,
I want to know how to make two boudnary lines (or two components) move in parallel. In the model attached, one line (domain 1) is fixed, and I want to keep the other line (domain 12) parallel to the fixed line.
I cannot find any built-in features suitable for this problem. Is it possible to use weak constraints to solve the problem? And how?
Thanks in advance for your help.
With regards, Zhaozhen

use a Prescribed Displacement condition for your domain 12, then enter the constraints that will ensure it remains parallel to domain 1.

I cannot see any attached model, but it sounds a bit similar to this example, where two boundaries are parallel, but at a distance determined by the solution (the criterion is zero force resultant).
