*Panel Sections,Auxiliary

Purpose

To specify the auxiliary panels that make up an auxiliary body.

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*ELEMENT,AUXILIARY, *AUXILIARY, *PANEL,AUXILIARY and *PANEL SECTIONS,AUXILIARY) keywords have effectively been superseded by the integrated vessel/body features which provide a range of standard vessel and subsea component profiles.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

A block of lines which define a group of auxiliary panels repeated as often as necessary. The block of lines starts with a line defining the body name and the panel colour. It is followed by either of two types of line defining the auxiliary panels, which can be mixed and repeated as often as necessary.

Line defining the body name and panel colour:

BODY=Vessel Name/Node Number [, COLOUR=Colour]

Two types of lines for defining auxiliary panels:

List of Panels

or

GEN=Start Panel, End Panel [, Panel Increment]

The list of panels can contain up to 20 panel numbers. Panel Increment defaults to 1. Vessel Name/Node Number can be NONE if no motions are to be applied to the auxiliary body. Colour is entered as an RGB value, either as a hexadecimal number (prefixed by #) or a decimal number. The default colour is silver.

Table Input

Notes

(a)This table allows you to group together auxiliary panels into named auxiliary panel bodies. You may also associate the auxiliary body with a vessel or a node of the finite element discretisation data. If this option is invoked, the auxiliary panels translate and rotate with the vessel/node during the course of an analysis or series of analyses (static and dynamic). When viewed in the dynamic display, the motions of the auxiliary body will be clearly visible.

(b)You do not need to explicitly assign all auxiliary panels to auxiliary panel bodies. An auxiliary panel not assigned to a panel body remains stationary throughout all subsequent analysis phases. For example, you might want to visually check for interference between a riser or hose and a nominally fixed structure.

(c)The optional Panel Colour column enables you to assign different colours to different parts of the auxiliary body. By default, an auxiliary body is silver throughout. The RGB value refers to the Red, Green and Blue colour model that is widely used in computer graphics. The table below shows 16 standard RGB values in hexadecimal and decimal formats. These values are based on the four numbers: #00, #80, #C0, #FF (0, 128, 192, 255), which are then concatenated in the hexadecimal format to build a total value.
