Bulk Data Entry Defines parameters that control connectivity and
configuration checks for gap elements (CGAP and
CGAPG). Most of these parameters also affect contact elements that are
automatically created on CONTACT interfaces - see individual descriptions
for details.

Comments
- The GAPPRM entry
changes the default settings of control parameters for the gap elements connectivity
and checks for configuration errors. None of the parameters of this entry are
required.
- The gap alignment check controlled by the
default value of CKGPDIR = ERR applies correctly
to the most typical situations wherein there is an initial opening between bodies A
and B, and the gap element is used to enforce non-penetration condition. For cases
of overlapping meshes (combined with a prescribed coordinate system), the
REV value is appropriate - it allows both aligned and reversed
gap directions (respective to the gap axis defined by the prescribed system).
- This card is represented as a control card
in HyperMesh.
