1 nodes lie on the axis of their cylindrical or spherical transformation systems. The local coordinate systems at these nodes are not well-defined.



These are the current coordinates if geometric nonlinearity is accounted for during the step (see Defining an analysis); otherwise, the array contains the original coordinates of the point.





Transformation of coordinates is defined for 73 nodes that have no translational or rotational degrees-of-freedom. The coordinate transformation will be ignored.
