/SET

Block Format Keyword Defines a general entity set which can be referenced by other entities.

The sets can be a combination of different types of entities such as elements, nodes, segments, or parts. Each entity type is defined by a Key followed by a list of item_ID. A different entity can be added by including a different Key and more item_ID. The item_ID_n lines can be repeated for the same Key entity.

Key: Description
PART: Add parts using the default extraction options.
PART_D: Remove part (all segments from solid parts, or all edges from).
PART_GA or PART_AG: Add a part (all segments and all edges) using the generation option.
SHELL_GO or SHELL_OG: Add shell element by generation and reverse the normal direction.

Comments

Multiple lines of item_ID can be entered for a defined KEY_OP. It defines that a block and entities extraction operations are done on this block. If the OP=E option is used, the external segments or edges are extracted from the entities defined in the block.
The set_ID cannot use the same identifier as any group IDs in /GRNOD, /GRElement, /SURF, /LINE, /GRPART.
The set_ID from the /SET can be referenced in any entity that references a /GRNOD, /GRElement, /SURF, /LINE, /GRPART. A few examples would be /IMPDISP, /CLOAD, /INTER/TYPE7, or /SECT.
Non-existing item_ID_i or box_ID_i will be ignored and a warning message is printed in the Starter output file.
For Key=BOX or OP=B, all nodes of an entity must be in the box for the entity to be included in the set. For Key=BOX2 or OP=C, at least 1 node of an entity must be in the box for the entity to be included in the set.
When a set is referenced by a keyword, the entities referenced (nodes, surface, line, or elements) are automatically extracted from the set. For example:
Solid elements: only external segments or external edges from 3D and 2D solid elements are extracted by default. Key option OP=A can be used to get all segments and edges.

Shell elements: all edges are extracted by default. Key option OP=E can be used to get only free edges.

Nodes: all nodes are extracted from the set by default. Key option OP=E can be used to get only the nodes from an external segment of solid elements or nodes from the free edge of shell elements.

Entities are automatically extracted as:

Required Set	Contents
Node set, /GRNOD	`OP`=A (Default) All nodes of the selected entities. `OP`=E Nodes from external faces of the solid elements defined in each `Key` block. Nodes from free edges of the shell elements defined in each `Key` block. All nodes for the other elements.
Element set, /GRelement	All elements of the selected entities.
Surface, /SURF	`OP`=E (Default) Only the external faces of the solid elements defined in each `Key` block. All segments from shells elements. `OP`=A All segments from solid elements (external and internal). All segments from shells elements.
Line, /LINE	Default Only edges from the external faces of the solid elements defined in each `Key` block. All edges from shells elements. All edges from beam, truss, and spring elements. `OP`=A All edges from solid elements (external and internal). All edges from shells elements. All edges from beam, truss, and spring elements. `OP`=E Only edges from the external faces of the solid elements defined in each `Key` block. Only free edges from the shell elements defined in each `Key` block. Free edges from beam, truss, and spring element.
