APDL Command: NORL

Rotates nodal coordinate systems perpendicular to line normal


Line number containing the nodes to be rotated. If ALL, applies to all selected lines (see the LSEL command). If LINE = P, graphical picking is enabled.


The area number containing the selected lines. The normal of the line(s) selected is supposed to lie on this area. Defaults to the lowest numbered selected area containing the line number.


Direction of the normal. If NDIR = -1, the nodal coordinate system is rotated in the opposite direction of the line normal. The default is the same direction as the surface normal.


The NORL command rotates the X-axis of the nodal coordinate perpendicular to the line normal. The rotated nodal coordinate systems may be displayed through the /PSYMB command. In case multiple lines are selected, there could be conflicts at the boundaries. If a node belongs to two lines that have a different normal, its nodal coordinate system will be rotated to the line normal with the lowest number. Keep the following in mind when using the NORL command:

If the nodal coordinate system is parallel to the global Cartesian system, it is not displayed through the /PSYMB command.

Previously specified rotation on the selected nodes are overridden.
