Mapdl.nrotat(node1='', node2='', ninc='', **kwargs)

Rotates nodal coordinate systems into the active system.


node1, node2, ninc

Rotate nodes from NODE1 to NODE2 (defaults to NODE1) in steps of NINC (defaults to 1). If NODE1 = ALL, NODE2 and NINC are ignored and all selected nodes [NSEL] are rotated. 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).


Rotates nodal coordinate systems into the active coordinate system. Nodal coordinate systems may be automatically rotated into the active (global or local) coordinate system as follows: Rotations in Cartesian systems will have nodal x directions rotated parallel to the Cartesian X direction. Rotations in cylindrical, spherical or toroidal systems will have the nodal x directions rotated parallel to the R direction. Nodes at (or near) a zero radius location should not be rotated. Nodal coordinate directions may be displayed [/PSYMB]. Nodal forces and constraints will also appear rotated when displayed if the nodal coordinate system is rotated.

ANSYS LS-DYNA (explicit dynamics) does not support the NROTAT command. If you have rotated nodes in the implicit phase of an implicit-to- explicit sequential solution, you must rotate the nodes back to the global Cartesian direction before switching from implicit to explicit elements (ETCHG,ITE). Use the EDNROT command in the explicit run to maintain the same displacement constraints as were used on rotated nodes in the implicit run.

Note:: : When the nodal coordinate systems are defined, they remain parallel to the global Cartesian system unless subsequently rotated.

Previously specified rotations on the specified nodes are overridden.

See the NMODIF, NANG, and NORA commands for other rotation options.
