Required parameters
 ELSET

Set this parameter equal to the name of the element set containing the IRStype elements or the threedimensional 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 exactly one node.
This parameter is relevant only when the NAME parameter is used.
 TYPE

Set TYPE=SEGMENTS to create a twodimensional rigid surface in the $\left(X,\u2006Y\right)$ plane for planar models or in the $\left(r,\u2006z\right)$ plane for axisymmetric models by defining connected line segments.
Set TYPE=CYLINDER to define a threedimensional rigid surface by providing connected line segments and then sweeping them along a specified generator vector.
Set TYPE=REVOLUTION to define a threedimensional rigid surface by providing connected line segments, which are given in an $\left(r,\u2006z\right)$ plane and are rotated about an axis.
Set TYPE=USER to define a rigid surface via user subroutine RSURFU.
Optional parameters
 FILLET RADIUS

This parameter can be used with TYPE=SEGMENTS, TYPE=CYLINDER, or TYPE=REVOLUTION to define a radius of curvature to smooth discontinuities between adjoining straightline segments, adjoining circulararc segments, and adjoining straightline and circulararc segments. It has no effect on rigid surfaces defined with TYPE=USER.
No data lines are needed for TYPE=USER
