Define a spatial enforced displacement constraint normal to the model
The spatial type of enforced displacement constraint lets you map the field directly to a global or local coordinate system.
Choose Home tab→Loads and Conditions group→Enforced Displacement Constraint .
In the Enforced Displacement Constraint dialog box, select Normal – spatial 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 Magnitude group, select a method from the Specify Field list to apply an enforced displacement constraint that varies spatially. You can use an existing field or create a new field. For more information, see Using fields and expressions to define boundary conditions.
(Optional) Enter a Scale Factor for the field.
Click OK.The constraint is applied to the model.
