SURFACE
2. Face or edge identifier label (see “Defining element-based surfaces,” Section 2.3.2 of the
ABAQUS Analysis U ser’s Manual, for the face and edge identifiers for various elements) or
the “word” EDGE (optional).
Repeat this data line as often as necessary to defin e the surface.
Data lines to define a surface using nodes or node sets when the TYPE=NODE parameter is used:
First line:
1. Node set name or node number.
2. Cross-sectional area or distributing weight factor. In ABA QUS/Standard contact calculations,
the default is the area specified in the associated
*
SURFACE INTERACTION option if the
surface is defined in a contact pair; otherwise, a unit area is used. In A BAQ US/Explicit the
cross-sectional area used for contact pair calculations for node-based surface nodes is always
set to 1.0 regardless of the value specified here. If the surface is used in a
*
COUPLING or
*
SHELL TO SOLID COUPLIN G definition, the default distributing weight factor is zero.
Repeat this data line as often as necessary to defin e the surface.
Data lines to define a surface using a plane cutting through the given element sets when the
TYPE=CUTTING SURFACE parameter is used:
First line:
1. X-coordinate of a point on the cutting plane in the initial configuration.
2. Y-coordinate of a point on the cutting plane in the initial configuration.
3. Z-coordinate of a point on the c utting plane in the initial configuration.
4. X-component of a normal to the cutting plane in the initial c onfiguration.
5. Y-component of a normal to the cutting plane in the initial configuration.
6. Z-component of a normal to the cutting plane in the initial configuration.
Second line:
1. List of elements or element set labels to be cut by the cutting plane to generate an element-based
surface that is an approximation to the cutting plane. A blank data line can be specified to
generate a surface by cutting the whole model.
Repeat this data line as often as necessary. Up to 16 entr ies are allowed per line.
No data lines are n eeded for TYPE=USER.
Data lines to define surfaces created with TYPE=SEGMENTS:
First line:
1. The “word” START.
2. Global X-coordi nate or r-coordinate of the starting point of the line segments.
