Default Stent Crimping in ANSYS

I am trying to simulate the ‘crimping’ of a certain geometry which can be considered as an elementary part of a cardiac stent. The geometry is basically a ring with a uniform cross section – the outer surface of this geometry falls on the surface of a cylinder. I am applying the load as a pressure on the outer surface. What I expect is the entire ring to be compressed / ‘crimped’ to a smaller radius due to the external pressure. But when I run the simulation, the entire geometry seems to translate and move sideways. Can you tell me what I am doing wrong?

See attached for files and results screenshots.

hi, i'm trying to do the same simulation on the same type of stent, does it bother you to send me your project ? it's for a university project.
