Zero-Valued Boundary Constraint dialog box (Abaqus)

Type	Appears when you create the zero-valued boundary constraint at the step level (in the Simulation Navigator, under the active step, right-click Constraints→New Constraint→User Defined Constraint).Select Zero-Valued Boundary to apply a constraint to one or more DOFs.
Destination Folder
Constraint Container	Specifies the folder in the Simulation Navigator in which to store the boundary condition. 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 listing 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 geometry or FE entities on which to apply the constraint. Use the Excluded options to remove individual entities, such as edges, from your selection.
Stacked Smart Selector Methods	Opens the Smart Selector Methods dialog box where you can specify a progression of smart selection filters.For more information, see Smart Selector Methods dialog box.
Direction
Displacement CSYS	Sets the coordinate system that the software uses to apply the constraint. You can select the global cyclic analysis (Global Cyclic Analysis) or the coordinate system currently defined for the selected nodes or geometry (Existing), or you can create one of the following types of local coordinate systems: Cartesian, Cylindrical, Spherical.Note: The Global Cyclic Analysis coordinate system is available only if it is defined in the FEM.
Local	Lets you create or select a local coordinate system.
Degrees of Freedom
DOF1 through DOF6	Defines the magnitude of the enforced displacement for each of the six degrees of freedom (DOF).FixedAllows no movement in the DOF (degree of freedom).FreeAllows free movement in the DOF.Note: When the 2D Solid Option is set, the DOF1–DOF3 options are specific to an axisymmetric analysis on the axisymmetric plane and rotational axis.DOF1 is the radial direction.DOF2 is the normal direction.DOF3 is the axial direction.
All Free	Sets all DOF to free.
All Fixed	Sets all DOF to fixed.
Fix DOFs at their Final Values
Fixed	Abaqus Structural analyses onlyKeeps the specified DOFs fixed at their final values from the last General analysis step and uses the values for the start of the next step.
Card Name	Displays the name of the solver card for the constraint.
