*SLIDE LINE
18.19 *SLIDE LINE: Specify slide line surfaces on which deformable structures may
interact.
This option is relevant only for slide line and tube-to-tube contact elements. It is used to define the slide line
and to specify which set of contact elements interacts with it.

Required parameters:
ELSET
Set this parameter equal to the name of the element set containing the slide line or tube-to-tube
contact elements that interact with the slide line being defined.
TYPE
Set TYPE=LINEAR to define a slide line made up of linear segments. This parameter should be
used when first-order elements make up the model.
Set TYPE=PARABOLIC to define a slide line made up of parabolic segments. This parameter
should be used when second-order elements make up the model. In this case the slide line should
consist of an odd number of nodes, where the odd nodes on the slide line are associated with the
ends of parabolic segments.
Optional parameters:
EXTENSION ZONE
Set this parameter equal to a fraction of the end segment length by which either end of an open slide
line is to be extended to avoid numerical round off errors associated with contact modeling. The
value given must lie between 0.0 and 0.2. The default value is 0.1.
GENERATE
Include this parameter to allow incremental generation of node numbers along a slide line.
