NSYM, Ncomp
, INC
, NODE1
, NODE2
, NINC
Generates a reflected set of nodes.
Ncomp
Symmetry key:
X | — | X (or R) symmetry (default). |
Y | — | Y (or θ) symmetry. |
Z | — | Z (or Φ) symmetry. |
INC
Increment all nodes in the given pattern by INC
to
form the reflected node pattern.
NODE1
, NODE2
, NINC
Reflect nodes from pattern beginning with NODE1
to NODE2
(defaults
to NODE1
) in steps of NINC
(defaults
to 1). If NODE1
= ALL, NODE2
and NINC
are
ignored and pattern is all selected nodes [NSEL]. If NODE1
=
P, graphical picking is enabled and all remaining command fields are ignored
(valid only in the GUI). A component name may also be substituted for NODE1
(NODE2
and NINC
are ignored).
Generates nodes from a given node pattern by a symmetry reflection. Reflection is done in the active coordinate system by changing a particular coordinate sign. Nodes in the pattern may have been generated in any coordinate system. Nodal rotation angles are not reflected.
Symmetry reflection may be used with any node pattern, in any coordinate system, as many times as desired. Reflection is accomplished by a coordinate sign change (in the active coordinate system). For example, an X-reflection in a Cartesian coordinate system generates additional nodes from a given pattern, with a node increment added to each node number, and an X coordinate sign change. An R-reflection in a cylindrical coordinate system gives a reflected "radial" location by changing the "equivalent" Cartesian (i.e., the Cartesian system with the same origin as the active cylindrical system) X and Y coordinate signs. An R-reflection in a spherical coordinate system gives a reflected "radial" location by changing the equivalent Cartesian X, Y, and Z coordinate location signs. Nodal coordinate system rotation angles are not reflected.
