What is difference between Gap tool (in Contact tool under Post Processing) compared to the Relative Displacement (ACT extension)? When should one be using one or the other?

      Contact Gap tool measures gap between contact and target faces provided the maximum gap is less than the Pinball Radius. If Pinball Radius is smaller than the gap, it is not stored in the results file to save the space. Relative Displacement extension can be used in case of large deformation leading to gaps larger than the Pinball Radius. It must be noted that if there is an initial gap between the contacts, relative displacement at any location would be (final gap – initial gap).
