RIGID SURFACE: D efine an analytical rigid surface.
This option must be used when defining the seabed for three-dim ensional 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
Type: Model data

SURFACE
Required parameters:
ELSET
Set this parameter equal to the nam e of the element set containing the IRS-type elements or the
three-dimensional drag chain elements that may interact with 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 equal to either the node number of the rigid body reference node or the name of
a node set containing the rigid body reference node. If the name of a node set is chosen, the node
set must contain exac tly 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.
