Surface to Surface (SFSF)
The surface to surface constraint consists of a surface on one body rolling and sliding on the surface of a second body. Each of the surfaces are required to have a unique contact point. The surface to surface joint constrains the two surfaces as follows: the surfaces have exactly one contact point, and the normal at the contact point for each is anti-parallel.
- Two reference surface entities (created using the Surfaces panel ).
- Two markers that belong to Body 1 and Body 2 of the joint and are located appropriately so that the surface entity can be meaningfully described as belonging to the coordinate system of the reference marker.
