Create a selection recipe for multiple nodes or elements

The Label Range strategy described here lets you select multiple nodes or elements as identified by their labels. Alternative ways to select multiple nodes or elements include:

• Adding related element and node adapters to a single-node strategy in a stacked selection recipe.

• Using multiple single-node strategies in a stacked selection recipe.

• Using a proximity strategy to select all nodes near a particular point, mesh point, curve, or polygon edge or face.

• Using a bounding volume strategy to select nodes, elements, or both within or outside of a defined area.

Note:

If you add adapters to a stacked selection recipe, the selection recipe might select other types of entities, such as curves, edges, faces, or vertices.

1. in the Simulation Navigator, right-click the Selection Recipes node.To create a single-strategy selection recipe, choose New Selection Recipe.To create a stacked selection recipe that can include additional strategies or adapters, choose New Stacked Selection Recipe.

2. In the Name box, type a unique name for the selection recipe.

3. From the Strategy list, select Label Range.

4. If you are creating a stacked selection recipe, click Add .

5. From the Input Filter list, select the option that indicates where the nodes or elements that you want to select exist.For example, if the same node IDs exist in two different assembly FEM components, you might select Component to select the nodes from a particular component.

6. If you selected Mesh or Component from the Input Filter list, in the Input Filter subgroup, click Select Object and then select the appropriate object.

7. From the Entity Type list, select the type of entity that you want to select (Node or Element).

8. In the box in the Labels group, type the range of node or element labels to include in this selection recipe.Separate individual numbers with a space or comma, and contiguous numbers with a hyphen or colon. For example, to select node 100 and nodes 115–120, type 100 115-120 or 100, 115:120.If you click Add Label Selection , the specified labels no longer appear in the Label Range Strategy dialog box. To view them, as well as to edit, cut, copy, or paste the labels, click Edit Label Selection .Tip: You can select nodes or elements in the graphics window by clicking to open the Target Selection dialog box.

9. (Optional) If you are creating a single-strategy selection recipe and want to highlight the selected entities in the graphics window, click Show Result . To stop highlighting the entities and activate the options in the dialog box so that you can change the selection recipe as needed, click Undo Result .If you are creating a stacked selection recipe, you can highlight the selected entities after you click OK in the Label Range Strategy dialog box.Tip: To see interior entities, choose View tab→Visibility group→See-Thru All .

10. Click OK.If you are creating a single-strategy selection recipe, the Create Selection Recipe dialog box closes, and the selection recipe appears under Selection Recipes in the Simulation Navigator.If you are creating a stacked selection recipe, the Label Range Strategy dialog box closes, and the Create Stacked Selection Recipe dialog box reappears.Tip: If you are creating a stacked selection recipe and 0 appears in the Count column in the strategy list table, the selection recipe is not selecting any entities. You might have specified a range that does not exist in the model or the selected mesh or component FEM. To modify the strategy, right-click the strategy in the list and choose Edit.When you edit a label range strategy, you cannot change the input filter. However, you can select a different mesh or component, or type a different label range.To use a different input filter, you must delete the existing strategy. To do this, right-click the strategy in the list and choose Delete. Then repeat steps 4–10 to create a new strategy.

11. (Optional) To narrow or widen the scope of your selection, select another strategy or an adapter from the Strategy list, click Add , and then complete the displayed dialog box (if any).For example, you might select Bounding Volume to limit the selected nodes to those within a defined area, or select Related Elements to select all of the elements connected to the specified nodes.

12. Click OK in the Create Stacked Selection Recipes dialog box.The selection recipe appears under Selection Recipes in the Simulation Navigator.
