# Sets

Set entities define and store lists of entity IDs for entities, sets of sets, or lists of set IDs.

Sets can only be generated for certain entity types.

Sets do not have a display state in the modeling window.

## Abaqus Cards

User Comment blocks are supported for all sets, and will be preserved during the import and export of the Abaqus input deck.

Sets using the GENERATE parameter can be expanded upon import by enabling the Expand sets defined by range option from the File Options dialog, which opens when you import a solver deck. This option is useful when node/element IDs are renumbered during import.

*EMBEDDED ELEMENT Specify an element or a group of elements that lie embedded in a group of “host” elements in a model.

When reading input decks that were not created in Engineering Solutions, an attempt is made to create two sets for each set found: one containing elements and one containing nodes. You can delete the unnecessary set. Sets that are created are maintained as node or element sets by using the $HMSET comment cards.

The sets can be composed of grids, elements, design variables, MBD entities, mode numbers, frequencies or times for reference by other input definitions. In addition to the definition of entity sets through the explicit selection of the constituents, it is possible to define a set of nodes or a set of elements through a combination of formulaic expressions. Sets that are created in Engineering Solutions are maintained on I/O by using the$HMSET comment cards.
