Submodel Constraint dialog box (Abaqus)

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 one of the following types of coordinate systems or you can create one: Global Cyclic AnalysisThe global cyclic analysis coordinate system.Note: The Global Cyclic Analysis coordinate system is available only if it is defined in the FEM. ExistingThe coordinate system currently defined for the selected nodes or geometry. You can also create one of the following types of local coordinate systems: Cartesian, Cylindrical, or Spherical.
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.
Submodel Boundary ParametersNote: All submodel constraints in a given step must have the same global steps, increments, and scales. Therefore, the submodel boundary parameters, Step Number, Increment Number, and the Scale and Adjust the Time Variable for Driven Nodes Amplitude Functions check box must be the same across all submodel constraints in a step. The solver does not issue a warning if the parameters are different and it generates an input file. Note that parameters Absolute Exterior Tolerance and Exterior Tolerance can be different because the solver writes them to a separate *SUBMODEL card with the associated node sets.
Absolute Exterior Tolerance	Sets the amount by which a driven node of the submodel can lie outside the region of the elements of the global model.
Exterior Tolerance	Sets the fraction of the average element size in the global model by which a driven node of the submodel can lie outside the region of the elements of the global model. The default is 0.05.
Step Number	Sets the step of the global model history that is to be used for the driven variables in the current submodel analysis step.
Increment Number	Sets the increment number of the global model history that is to be used for the driven variables in the current submodel analysis step.
Scale	Sets the value by which the driven variables read from the global analysis are to be scaled.
Adjust the Time Variable for Driven Nodes Amplitude Functions	Scales the time variable of each driven node's amplitude function to match the submodel analysis step time.
Card Name	Displays the name of the solver card for the constraint.

Additional magnitude options for boundary conditions
You can define the magnitude with a constant value, expression, or field. You can:Type a constant value directly in the box.Type an expression directly in the box. As you begin to type the expression, tooltips provide hints about valid parameter names. If you type an invalid or incomplete expression, the warning icon appears next to the box.Click and select:
Expression	Opens the Expressions dialog box, where you can select an existing expression or create a new one.For more information about expressions, see Expressions.
For more information about other options in the list, see Additional magnitude options.
