CONSTRUCT SET

   

This command is used to group entities for use in further commands.

CONSTRUCT SET has the following sub-commands:

2.3.8.1 CONSTRUCT SET [Set_name] APPEND - Append to a set

2.3.8.2 CONSTRUCT SET CLOSE [Set_name] - Close a set

2.3.8.3 CONSTRUCT SET Set_name COMPLEMENT - Generate the complement of two sets

2.3.8.4 CONSTRUCT SET Set_name INTERSECT - Generate the intersection of two sets

2.3.8.5 CONSTRUCT SET OPEN [Set_name] [TYPE] - Open a new set

2.3.8.6 CONSTRUCT SET [Set_name] REMOVE - Remove from a set

Closing a set
The checks that are performed when a set is closed will depend on how the set was first opened. Sets that have been created with the default options will be automatically completed, so that all parts used in the definition of higher order parts will be added to the set. Thus, if a body is added to a set, then when the set is closed all the surfaces, lines and points that make up the body are also added to the set.

Sets that have been initially opened with the LIST or LOOP keywords will be checked and modified so that they contain only parts of the given type and will be checked for validity. The parts in these sets do not need to be given in topological order.

Sets that have been initially opened with the INCOMPLETE keyword are not completed or checked.

Ordering of parts
From highest to lowest, the order of parts is Bodies, Surfaces, Lines and Points.

Set types
FEMVIEW sets may be either element or node based. When operating on the contents of a set, the operation is mapped if necessary to be consistent with the set type, ie, element operations are converted to nodes and node operations are converted to elements.
