A Constraint Settings Section node () is a special section that a feature with constraints uses. A feature always have this section when there is at least one constraint. Add this node when you want to include constraint settings although there is no constraints for the feature, or if you want to modify the content of the section. The section always contains a selectable input that allows a user to select the type of constraint. It also contain a check box for weak constraints when necessary. Similar to the Selectable Input node, Allowed Values subnodes defines the allowed values for the selectable input of this section. There can only be one Constraint Settings Section node for each physics feature.

To add a Constraint Settings Section first add a feature node (for example, a Generic Feature, Domain Condition, or Device Model Feature), then:

The Settings window has the following sections:

Under Supported options defined by child nodes, the Default value list can either be the First allowed value (the default) or Custom default. The latter allows you to enter an arbitrary default value as long as it is among the allowed values defined for the input.

In the Condition field, enter a common logical expression (for example, something like isActive(Property1.name) && Propery1.name='aa') for hiding the Use weak constraint check box. When the common expression is true, the constraint type logic decides what to display, but when the expression is false, the Use weak constraint check box is always hidden. You activate this option by selecting the Include common condition for allowing weak constraints check box.

The Default method list controls the default value for the constraint method setting in the Constraint Settings section for physics features that adds constraints. The options are Elemental (the default) or Nodal.

In the Category for hiding section list, choose among possible options to hide the section with respect to the global display settings Advanced physics options (the default), and Stabilization. The option None disables the hiding of this section; for None, select the Section is initially collapsed check box to make the section initially appear as collapsed instead of expanded.

From the Show exclude sections list, choose If added by any constraint or Always. The Add exclude sections list has the options All dimension below the feature dimension or Custom. If you choose Custom, add the applicable entity dimensions to the Restrict to entity dimensions list. The exclude selection functionality can be useful to avoid conflicting constraints in structural mechanics, for example.
