Purpose

To add subsea components to the structural animation for enhanced visual appeal.

Theory

Refer to Auxiliary Bodies for further information on this feature.

Keyword Format

A block of lines defining a structural body. The block begins with a mandatory pair of lines defining the body name and its physical location. This is followed by an optional line associating the body with a node of the finite element discretisation. This is then followed by additional optional lines associating a predefined profile with the body. The entire block may then be repeated for subsequent bodies.

Mandatory pair of lines defining the body name and its physical location:

BODY=Body Name

LOCATION=X, Y, Z

Optional line associating the body with a node of the finite element discretisation:

[NODE=Node (Number or Label)]

Mandatory line associating a predefined profile with the body:

PROFILE=Profile Type

If the profile type is user-defined, then another mandatory line immediately follows:

FILE=File Name

Optional line defining overall dimensions for the body:

[DIMENSIONS=Height, Length, Width]

If you specify a node label rather than a node number, it must be enclosed in { } brackets. Profile Type may be BOP, CALMBUOY, PLET, ROV or USER. If a file name or any part of its path contains spaces then it should be enclosed in double quotation marks. If dimensions are not explicitly defined, some generic dimensions are applied automatically to the body.

Table Input

Input:	Description
Body Name:	A descriptive name for the body.
X, Y, Z:	The global X, Y, & Z coordinates of the centre of the body at solution initiation.
Node:	The node (number or label) whose motions govern the movement of the body. If you specify a node label rather than a node number, it must be enclosed in { } brackets.
Profile:	The profile type used to represent the body. You may choose from a range of standard profiles, or opt to use a customised profile.
User Profile:	If you are using a customised profile, this input defines the location of the profile file. See Note (a).
Height, Length, Width:	The overall dimensions of the profile in the global X, Y and Z directions. If dimensions are not explicitly defined, some generic dimensions are applied automatically to the body.

Notes

(a)The profile is defined in XML format, and several sample profiles are available in your local Flexcom installation directory, under the sub-folder ‘StandardProfiles’. Each profile file contains a range of input data, capable of defining standard shapes such as boxes, cylinders etc., as well as arbitrary shapes defined by a series of points about which a mesh is constructed. All locations within the profile file are defined with respect to a local origin (0, 0, 0). The location of this origin in the global axis system is then defined by the X, Y, & Z coordinates of the body centre. Should you require any assistance in creating your own customised profile, feel free to contact sw.support@woodplc.com and our support team will discuss the format of the XML information in more detail.
