Purpose

To define auxiliary nodal coordinates in the global Cartesian coordinate system.

Theory

Refer to Auxiliary Bodies for further information on this feature.

Note also that the old auxiliary body keywords (*NODE,AUXILIARY, *ELEMENT,AUXILIARY, *AUXILIARY, *PANEL,AUXILIARY and *PANEL SECTIONS,AUXILIARY) keywords have effectively been superseded by the integrated vessel/body features which provide a range of standard vessel and subsea component profiles. Refer to *VESSEL,INTEGRATED and *BODY,INTEGRATED for further information.

Keyword Format

One type of line repeated as often as necessary.

Node, X Co-ordinate, Y Co-ordinate [, Z Co-ordinate]

Table Input

Input:	Description
Node:	The number of the auxiliary node being defined.
X Coordinate:	The nodal coordinate in the global X-direction.
Y Coordinate:	The nodal coordinate in the global Y-direction.
Z Coordinate:	The nodal coordinate in the global Z-direction. This defaults to a value of 0.

Notes

(a)Auxiliary nodes, elements and bodies allow you to include objects in your model that are not part of the finite element discretisation, but which are included for illustrative purposes only. Outline vessel models are the most common example of such objects.

(b)Auxiliary nodes and structural nodes (nodes that are included in the finite element discretisation) cannot use the same node number. Each node in the model must be assigned a unique node number irrespective of whether it is a structural node or an auxiliary node.
