Reply To: How to apply Compression-only Support?

[Harshvardhan]

 

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:

compression only and bearing support

I hope this helps.
