Optional parameters
- LINE
-
Set LINE=P to generate the nodes along a parabola. In this case the user must define an extra point, the midpoint between the two end points.
Set LINE=C to generate the nodes along a circular arc. In this case the user must define an extra point, the center of the circle.
If this parameter is omitted, the nodes will be generated along a straight line.
- NSET
-
Set this parameter equal to the name of a node set to which the nodes will be assigned. The two end nodes will also be included in the node set. Node sets created or modified with this option will always be sorted.
- SYSTEM
-
Set SYSTEM=RC (default) to define the extra node in a Cartesian coordinate system. Set SYSTEM=C to define the extra node in a cylindrical coordinate system. Set SYSTEM=S to define the extra node in a spherical coordinate system. See Figure 1.
Data lines to generate nodes incrementally
- First line
-
Number of the first end node (it must have been previously defined).
-
Number of the second end node (it must have been previously defined).
-
Increment in the numbers between each node along the line. The default is 1.
-
Number of the third node giving the extra point (if required; it must have been previously defined).
-
First coordinate of the extra point (if required).
-
Second coordinate of the extra point (if required).
-
Third coordinate of the extra point (if required).
- The following entries are used only for a circular arc equal to or larger than 180°:
-
First component of a normal to the circular arc.
-
Second component of a normal to the circular arc.
-
Third component of a normal to the circular arc.
-
Repeat this data line as often as necessary.
