Named entities are entities which are given a name but are not collected or organized into containers. Examples of named entities include materials and properties. Some named entities also have a display state, on or off, which control the display of that entity in the graphics area. The display state of named entities can be controlled using the Model browser. All named entities have active and export states. The active state of a named entity controls the display state of the named entity and the listing of the named entity in the Model browser and any of its views. The export state of a named entity controls the export of that entity to a solver deck. The active and export states of named entities can be controlled using the Entity State browser.
