Required parameters
- REF NODE
-
Set this parameter equal to either the node number of the reference node or
the name of a node set containing the reference node. If the name of a node set
is chosen, the node set must contain exactly one node.
Optional parameters
- ALPHA
-
Set this parameter equal to the thermal expansion coefficient.
- ORIENTATION
-
Set this parameter equal to the name given to the
ORIENTATION definition (Orientations)
that specifies the initial orientation of the local system in which the
constrained degrees of freedom are defined.
Data
lines to specify the nodes and degrees of freedom to be
constrained
- First
line
-
Node number or node set label.
-
First degree of freedom constrained. See
Conventions
for a definition of the numbering of degrees of freedom in
Abaqus/Standard.
If this field is left blank, all degrees of freedom will be constrained.
-
Last degree of freedom constrained. If this field is left blank, the degree
of freedom specified in the second field will be the only one constrained.
Repeat this data line as often as necessary to specify
constraints at different nodes and degrees of freedom. When the ORIENTATION parameter is specified, the degrees of freedom are in the
referenced local system in the initial configuration; otherwise, they are in
the global system. In either case these directions will rotate with the
reference node in large-displacement analyses (when the NLGEOM parameter is included on the
STEP
option).
