TypeModel data
LevelPartPart instance
Abaqus/CAENot applicable; nodes are generated when you
mesh the model.
Optional parameters
 BIAS

Include this parameter to bias the spacing of the nodes being generated
toward one end of the line of nodes being generated. Set this parameter equal
to the ratio of adjacent distances between nodes along each line of nodes
generated, as the nodes go from the first bounding node set to the second. If
the BIAS parameter is less than one, the nodes are concentrated toward
the first bounding node set; if it is greater than one, the nodes are
concentrated toward the second bounding set. The value of the parameter must be
positive.
The BIAS and SINGULAR parameters are mutually exclusive.
 NSET

Set this parameter equal to the name of the node set to which the nodes
created by this operation (including the bounding nodes) will be assigned. Node
sets generated by this option are always sorted node sets.
 SINGULAR

This parameter applies only to
Abaqus/Standard
analyses.
Include this parameter for fracture mechanics calculations with secondorder
isoparametric elements to create a “quarter point” cracktip element and bias
the remaining elements. Set SINGULAR=1 or 2, depending on whether the first or the second bounding node
set represents the crack tip.
The BIAS and SINGULAR parameters are mutually exclusive.
 TWO STEP

This parameter is meaningful only if the BIAS parameter is used. When this parameter is included, the BIAS value is applied only at each second interval along the line;
therefore, the midside nodes of secondorder elements will be at the middle of
the two adjacent intervals.
Data lines to fill in
nodes between two bounds
 First line

Name of the node set defining the first bound of the region.

Name of the node set defining the second bound of the region.

Number of intervals along each line between bounding nodes.

Increment in node numbers from the node number at the first bound set end.
The default is 1.
Repeat this data line as often as necessary, one line per
region to be filled by this
option.
