Define an enforced displacement constraint using components
The Components type lets you define an enforced displacement constraint in terms of a global or local coordinate system.
Choose Home tab→Loads and Conditions group→Enforced Displacement Constraint .
In the Enforced Displacement Constraint dialog box, select Components from the Type list.
In the Model Objects group, click Select Object and select the geometry or FE entity to which the enforced displacement constraint will be applied.
In the Direction group, select the coordinate system to use to define the constraint.
(Optional) If you set Coordinate System to a local type, in the Local list, choose the method for specifying the coordinate system. For more information, see CSYS dialog box.
In the Degrees of freedom group, define the enforced displacement constraint magnitude for each DOF in one of these ways:Select Expression to use a constant value or expression to define the magnitude. For more information, see Expressions. Select Field to define enforced displacement constraint magnitude that varies with frequency, time, or temperature. For more information, see Using fields and expressions to define boundary conditions.
(Optional) In the Distribution group, select the method for distributing the enforced displacement constraint.Select Constant to apply the magnitude as a constant value.Select Spatial to use a unitless field to map the magnitude to the nodes.
Click OK.The constraint is applied to the model.
