Enforced Displacement Constraint dialog box (Abaqus)

Type	Specifies how the enforced displacement constraint is defined.ComponentsLets you define a constraint by specifying a magnitude for the individual degrees of freedom (DOF1 and DOF2) that are available on the axisymmetric XY plane.Magnitude and DirectionLets you define the constraint by specifying the magnitude of the displacement in a single direction. NormalLets you define the constraint by specifying a displacement magnitude and a positive or negative (+/–) direction that is normal to the selected geometry or element faces.Components – SpatialLets you define the constraint as a constraint magnitude for the translational degrees of freedom only.
Destination Folder
Constraint Container	Specifies the folder in the Simulation Navigator in which the boundary condition is stored. The list includes the root container and existing folders that you created using the New Folder command. Examples of a root container include Load Container, Constraint Container, and Simulation Object Container.
Folder Manager	Displays a hierarchical list of existing folders. To create a new folder, right-click any level of the hierarchy and choose New Folder.
Model Objects
Group Reference	Lets you apply the constraint to a group.For more information, see Group Reference options.
Select Object	Lets you select the objects to apply the constraint to. ExcludedLets you remove individual entities from within your selected object.
Magnitude
Displacement	Appears when Type is set to Magnitude and Direction or Normal. Lets you define the magnitude of the enforced displacement. For more information, see Additional magnitude options.
Specify Field	Appears when Type is set to Components – Spatial. Defines how the enforced displacement constraint is distributed over the nodes or elements in the selected area. Use the Scale Factor option to apply a uniform scale factor to the magnitude of the enforced displacement at each DOF.
Direction
Displacement CSYS	Appears when Type is set to Components or Components – Spatial. Sets the coordinate system used to apply the constraint. You can use the Existing coordinate system currently defined for the selected nodes or geometry, or select one of the following local coordinate systems: Cartesian, Cylindrical, or Spherical.
Specify Vector	Appears when Type is set to Magnitude and Direction.Lets you select or create a vector that defines the direction to apply the constraint to.
Reverse Direction	Appears when Type is set to Magnitude and Direction.Reverses the direction of the vector.
Degrees of freedom
DOF1 through DOF6	Appears when Type is set to Components.Defines the magnitude of the enforced displacement for each of the DOF. For more information, see Additional magnitude options.Note: When the 2D Solid Option is set, the DOF1–DOF2 options are specific to an axisymmetric analysis. The displacement and rotation degrees of freedom in axisymmetric elements are referred to as follows:DOF1 is the r-displacement.DOF2 is the z-displacement direction.
Scale Factors
DOF1 through DOF3	Appears when Type is set to Components – Spatial. Lets you apply a uniform scale factor to the magnitude of the enforced displacement at each degree of freedom.
