controls how the projection onto the obstacle element (or node patch) is
performed.

- NORM or 1
- The projection of node GA (or slave
node for CONTACT) to the obstacle B is
performed along the normal to the surface of the
obstacle (a patch of nodes or an element face). If such
normal projection falls outside the patch of nodes or
element face (within 5% tolerance), an error message is
issued for GAPG elements, while no
contact element is created on the
CONTACT interface.
- SHORT or 2
- The node GA (or slave node for
CONTACT) is projected onto the
obstacle B along the shortest distance. For cases where
the normal projection falls within the bounds of the
obstacle, this coincides with the NORM
option. For cases where the normal projection falls
outside the obstacle, this option will choose the point
on the obstacle that is nearest to GA
or slave node.
