See attached zip folder. Contained within is an mp4 movie file. Of course, I didn't include all combinations, but you get the idea where this could lead.

You have a choice: 1. attempt to simulate pipes sliding around on top of these structures, or 2. make them stick to the structure and ensuring what happens between the structures works for the pipe.

What's truly secured to the structure doesn't care about structure displacements.

The secondary models won't be used to simulate temperature, friction, accelerations, or displacements.

You will INSTRUCT CAESAR what those displacements are to be.
