RIGID SURFACE: Define an analytical rigid surface.
This option must be used when defining the seabed for three-dimensional drag chain elem ents in
ABAQUS/Standard analyses. For all other cases the preferred options for defining analytical rigid surfaces
are the
*
SURFACE and the
*
RIGID BODY options.
Product: ABAQUS/Standard

SURFACE
Required parameters:
ELSET
Set this parameter equal to the name of the element set containing the IRS-type elem ents or the
three-dimensional drag chain elements that m ay interact w ith the rigid surface being defined.
The ELSET and NAME parameters are mutually exclusive.
NAME
Set this parameter equal to a label that will be used to refer to the rigid surface being created. This
surface name is used to define contact interaction with another surface through the
*
CONTACT
PAIR option.
The ELSET and NAME parameters are mutually exclusive.
REF NODE
Set this parameter equa l to either the node number of the rigid body reference node or the name of
a node set containing the rigid body r eference node. If the name of a node se t is chosen, the node
set must contain exactly one node.
This parameter is relevant only when the NAME parameter is used.
TYPE
Set TYPE=SEGMENTS to create a two-dimensional rigid surface in the
plane for planar
models or in the
plane for axisymmetric models by defining connected line segments.
