Answer:
The fastest way to create a contact solid between two surfaces is to first copy the original surface by using the Step Links option.
In the new Step Links tab, select the "Link surfaces with solid" option.
Select the template for this solid to be a standard Solid Type.
After copying and creating the new elements, select the Solid type to be a Contact. In the new tab, define the Contact Solid Type (for example, Full force transmission). Additionally, you will be able to select a pair of surfaces to have this contact. A list of available surfaces is generated automatically.
After defining the Contact Solid, it’s possible to change the side Surfaces to the type Without Thickness.
