*RIGID SURFACE
17.19 *RIGID SURFACE: Definean analytical rigid surface.
This option must be used when defining the seabed for three-dimensional drag chain elements in
ABAQUS/Standard analyses. For all other cases the preferred options for defining analytical rigid surfaces
are the *SURFACEand the *RIGID BODY options.
Product: ABAQUS/Standard
Type: Model data
Level: Part, Part instance

Required parameters:
ELSET
Set this parameter equal to the name of the element set containing the IRS-type elements or the
three-dimensional drag chain elements that may interact withthe rigid surface being defined.
The ELSET and NAME parameters are mutually exclusive.
NAME
Set this parameter equal to a label that willbe 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 equal to either the node number of the rigid body reference node or the nam e of
a node set containing the rigid body reference node. Ifthe n ame of a node set 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 planefor planar
models or in the planefor axisymm etric models by defining connected line segments.
