Understanding Structure Constraint Sets
Every constraint you add in the software is part of a constraint set. A constraint set is a collection of constraints that act together, and at the same time, on your model. Constraint sets cannot contain loads. For more information, see Guidelines for Structure Constraint Sets.
You can manage your constraint sets with the Constraint Sets dialog box in Structure and FEM mode Structure. When you click Home > Constraints > Constraint Sets, this dialog box opens with the following buttons:
New—Opens the Constraint Set Definition dialog box. Enter a name and optional description for the new constraint set.
* You can also access the Constraint Set Definition dialog box by clicking the New button in the Member of Set area on the Constraint and Symmetry Constraint dialog boxes.
Copy—Opens the Copy Constraint Set dialog box to enable you to enter a name for the copy, or accept the default name. When you click OK, the copy is added to the list in the Constraint Sets dialog box. The new constraint set includes copies of the same constraints as the original constraint set.
Edit—Opens the Constraint Set Definition dialog box to enable you to modify the information that you used to specify the highlighted constraint set.
Delete—Removes the highlighted constraint set.
Description—Displays the optional description you entered when you created the constraint set.
If you want the flexibility of treating each of your constraints separately, use a unique name and unique set name for each constraint. Remember, however, that an analysis can only access one constraint set.
Load and constraint sets provide a logical means of organizing your modeling entities so that you can define analyses effectively and clearly. A carefully considered approach to load and constraint set creation simplifies load and constraint selection when defining your analyses. Although the software permits you to create each load and constraint as a separate load set or constraint set, you can greatly reduce the number of selections you need to make for analysis definition by grouping your loads and constraints into sets.
