For Rigid Dynamics systems, you can specify a Contact Distance probe that produces a distance result, per time point, between the Contact and Target sides of a Contact Region.

Scoping

Scope this probe directly to an existing Contact Region (either manually or automatically created).

Output

The Contact Distance probe results are presented in the Graph and Tabular Data windows.

In addition, the application automatically inserts a tether (red line) between the contact sides. You can then animate the result to visually observe the change in contact distance over time, as illustrated below.
