Short entity identification labels to distinguish between the various geometry and mesh components in the study.
For a meshed Midplane or Dual Domain model, for example, the most common identifiers are "N" for node, and "T" for triangle.
Many modeling, meshing, and mesh repair dialogs contain input boxes for selecting specific entities in the model. As you select entities in the model by using the mouse, you will see the selected entities being listed with their identifiers, for example, N23 meaning node 23. You will also see entity identifiers used in a number of other places, for example on the Query Entities dialog in the Modeling menu or when defining selection lists.
The following table provides a complete list of identifiers:
| Identifier | Entity type |
|---|---|
| B | Beam element, a 2-noded element, for example, cold runner, cooling channel |
| C | Curve |
| N | Node |
| NBC | Nodal boundary condition, for example, injection location applied to mesh |
| R | Region |
| STL | STL body |
| S | IGES surface |
| SBC | Surface boundary condition, for example, loads applied to triangles |
| T | Triangle element, a 3-noded element in a Midplane or Dual Domain mesh |
| TE | Tetrahedral element, a 4-noded element in a 3D mesh |
| BD | CAD body |
| F | CAD face |
