We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi,
Compression only support works by creating a frictionless contact with a rigid surface. This rigid surface is not modelled geometrically. 
So, the surface scoped for compression only support can be assumed to be in a frictionless contact with a rigid body. It can slide and separate, but not go through the rigid surface.

If you select the walls of the hole for this support, it will be modelled as if a rigid pin with zero tolerance is inserted inside the hole.

More information on compression-only support can be found in the following links:
17.6.3.6. Compression Only Support
Structural Boundary Conditions | Ansys Innovation Courses
compression only and bearing support

I hope this helps.

Regards,
Harshvardhan
