Thank you for your answer, but I explained it not clearly. I attached the figure to make it more clearly.

I already have a valid frictional contact between the two separate solids. But I want to define the gap (distance) between these surfaces. As I said, these surfaces are parts of two separate solids. What I want to do is include the mathematical distance between this surface. If the global deformation of the solids and their surfaces causes these two surfaces to come together by this defined distance, the contact after that will be active. But if the deformation is less than this distance, it will behave as non-contact.
